Python insert tuple to list

Add Tuple to List in Python

Tuples and Lists are two of the most commonly used collection objects in Python. They both can store multiple elements and provide access to these elements using their indexes. There are a few differences associated with them as well.

Tuples are immutable, which means that once created they cannot be changed. Due to this, they require less memory and provide faster access to elements. Lists on the other hand are mutable and dynamic. They require more memory and access to elements is comparatively slow.

We will now discuss how to add tuple to list in Python.

Ways to Add Tuple to List in Python (adding the Tuple as An Element)

In this section of the article, we will discuss how to add a tuple as an element to the list.

Using the insert() Function to Add Tuple to List in Python

The insert() function can be used to add elements to a list at some specific position. We can provide the desired element along with the index in the function.

To add tuple to list in Python, we will provide the tuple as the element within the function.

In the above example, we had a list of tuples, and we added a tuple to this list using the insert() function.

Using the append() Function to Add Tuple to List in Python

The append() function is used to add elements towards the end of the list. We can specify the element within the function. In our example, we will add tuple to list in Python by specifying the tuple within the function.

Ways to Add Tuple to List in Python (adding the Tuple’s Elements to A List)

In this section of the article, we will insert the elements of a tuple into a given list. Several methods are discussed below.

Using the extend() Function to Add Tuple to List in Python

The extend() function accepts an iterable and adds its elements to the end of a list. We can specify the tuple in the function to add tuple to list in Python.

In the above example, we add the elements from the tuple to the list using the extend() function.

Using the += Operator to Add Tuple to List in Python

The += operator is termed as the concatenation operator that can combine elements from two iterables. We can add tuple to list in Python using this operator.

Remember that this operator only works for non-local objects (A variable that is not global nor local to a particular function).

Conclusion

To conclude, we discussed how to add tuple to list in Python. This was discussed in two sections.

In the first section, we discussed how to add a tuple as an element to the list. For this, we used the insert() function that can add elements at a given index in a list and the append() function that adds elements to the end of a list.

In the second section, we discussed how to add the tuple’s elements to a given list, essentially combining them both. The first method involved the use of the extend() function and we used the concatenation operator ( += ) in the second method. Both perform the same function without much time difference.

That’s all about how to add tuple to list in Python.

How To Append A Tuple To A List In Python

In this article, we will explain to you how to Append a tuple to a list in Python, like using the append() method, extend() method, += operator , and using insert() method. Hopefully, through this article, you can easily find an easy way to do that.

To Append a tuple to a list in Python

Using the append() method

Firstly, the best way is to use the append() method to append a tuple to a list in Python. This method will add the element to the end of the list.

Code Example

Let’s see the code example below.

myList = [] myTupple = ('Ronaldo', 'Messi', 'Neymar', 'Benzema') # Using the append() method to append a tuple into a list myList.append(myTupple) print("After appending myTupple into myList: ", myList)

After appending myTupple into myList: [('Ronaldo', 'Messi', 'Neymar', 'Benzema')]

Using the extend() method

The following way is using the extend() method to do it. This method will iterate over an integrable and then add each element to the end of the list.

myList = [] myTupple = ('Ronaldo', 'Messi', 'Neymar', 'Benzema') # Using the extend() method myList.extend(myTupple) print("After appending myTupple into myList: ", myList)

After appending myTupple into myList: ['Ronaldo', 'Messi', 'Neymar', 'Benzema']

Using the += operator

The next way is to use the += operator to append a tuple to a list in Python.

In this example, we will use the += to add the myTupple to the last index in a list.

myList = [] myTupple = ('Ronaldo', 'Messi', 'Neymar', 'Benzema') # Using the += operator to append a tuple into a list myList += myTupple print("After appending myTupple into myList: ", myList)

After appending myTupple into myList: ['Ronaldo', 'Messi', 'Neymar', 'Benzema']

Using the insert() method

The last way is using the insert() method. This method will insert the value to the specified position into the list.

Syntax: list.insert(i, ele)

• i: is the index you want to add the value to a list.

• ele: is an element you want to add to the list.

In this example, we will use the insert(1, myTupple) to add the myTupple to the first index in a list.

myList = [] myTupple = ('Ronaldo', 'Messi', 'Neymar', 'Benzema') # Using the insert() method to append a tuple to the first index of a list myList.insert(0, myTupple) print("After appending myTupple into myList: ", myList)

After appending myTupple into myList: [('Ronaldo', 'Messi', 'Neymar', 'Benzema')]

Adding Tuples to Lists in Python

Python is a very versatile language offering us various data structures. While programming in Python, we often work with lists and tuples. Both seem quite similar at first, but we can easily point out the differences with a closer look. According to what our program requires, we can make a fitting pick.

When working with lists, we might also come across a situation where we need to add a tuple to a list. There are two ways to execute it. We’ll be dealing with both ways in this article.

What are List and Tuple?

A list is a built-in data type in Python. It is a collection of ordered elements. It is used to store multiple items in a single variable, such as numbers or strings.

We should keep in mind that lists are mutable, meaning you can modify the elements in a list even after it has been created. You can also add or delete elements in a list. Lists are created by enclosing a sequence of elements in square brackets and separating them with commas. Here’s an example:

In this example, my_list is a list containing four elements: 1, 2, a, and b.

A tuple is also a built-in data type in Python. It is a collection of ordered and unchangeable (immutable) elements.

A tuple is very similar to a list, but the key difference is that while lists are mutable by nature, tuples aren’t. Once created, we cannot modify, add or delete the elements in a tuple. Tuples are declared by enclosing a sequence of elements in round brackets separated with commas. Here’s an example:

Now that we’ve looked into lists and tuples, let’s understand how to add a tuple to the end of a list.

Using the append() method

We can add a tuple to a list is by using the append() method. It is a built-in method of the list object. It is used to insert an element at the end of an existing list. When using append, an element gets added to the old list instead of a new list is returned. In this case, our element is a tuple.

The append() method adds a tuple to a list. It is a built-in method of the list object. It’s used to add an element to the end of an existing list. Rather than returning a new list when using append, an element is added to the existing list. Our element, in this particular case, is a tuple.

a = [1, 2, 3] b = (4, 5, 6) a.append(b) print(a)

Output of the above code:

In the above code, we have a list ‘a’ and a tuple ‘b’. We use the ‘append()’ to add ‘b’ to the end of ‘a’. We then print ‘a’.

Appending a tuple to a list using the concatenate operator

The concatenate operator can also be used to add a tuple to a list. We use the ‘+’ operator to combine two objects, such as two strings, two lists, or a list and a tuple.

The concatenate operator can be used to append a tuple to a list as shown below:

a = [1, 2, 3] b = (4, 5, 6) c = a + [b] print(c)

Output:

In this example, we create a new list called ‘c’ by concatenating list ‘a’ with the tuple ‘b’. The resulting list contains the original elements of list ‘a’ followed by the tuple ‘b’.

Which Method to Use When Adding a Tuple?

While both the approaches demonstrated above to produce the same result, there are some differences between the two methods that we should be aware of.

Firstly, the original list is modified when using the append() method, whereas, with the concatenate operator, a new list is created. With append() method, since the original list is modified, any reference to the list will also see the change. On the other hand, with the concatenate operator, since a new list is created, the original list remains unchanged.

Secondly, the append() method is more efficient than the concatenate operator when you only need to add one or two elements to the list. The append() method modifies the list itself, meaning it does not need to create a new list. On the other hand, the concatenate operator needs to create a new list, which can be slower if the list is large.

Thirdly, the concatenate operator is more versatile than the append() method. The + operator can concatenate two objects of any type, including lists, tuples, and even strings, whereas the append() method can only add elements to the end of a list.

Versatility of the concatenate operator:

a = [1, 2, 3] b = (4, 5, 6) c = "Hello" new_list = a+[b]+[c] print(new_list)

Output:

In this example, we combine list ‘a’, tuple ‘b’, and string ‘c’ using the concatenate operator. The new list contains all the elements in the order they were concatenated.

We are now familiar with two methods for appending a tuple to a list. While the concatenate operator creates a new list and is considerably more versatile, the append() technique alters the original list and is more effective when adding only a few elements. We can choose which method to work better for our code based on our need.

Python List insert() Method

The insert() method doesn’t return anything; returns None. It only updates the current list.

Example 1: How to Use np.insert() Method

GoT = ['Daenerys', 'Jon', 'Tyrion'] GoT.insert(1, 'Varys') print(GoT) 

Example 2: Inserting a Tuple (as an Element) to the List

To insert a tuple in List in Python, use the list.insert() method. We can also add a Tuple as an element to the specified position.

GoT1_list = ['Daenerys', 'Jon', 'Tyrion'] Friends1_tuple = ('Rachel', 'Monica', 'Phoebe') GoT1_list.insert(2, Friends1_tuple) print(GoT1_list)

So, it inserts an element at a given position. The first argument is the element index before which to insert, so a list.insert(index, element) inserts at the front of the list.

Example 3: AttributeError: ‘str’ object has no attribute ‘insert’

If we try to insert anything in a string because the string doesn’t have attribute insert().

# AttributeError string = "192111" string.insert(10, 1) print(string)

AttributeError: 'str' object has no attribute 'insert'

Example 4: Insert in a List Before any Element

listA = [11, 21, 19, 46, 18] # Element to be inserted element = 20 # Element to be inserted before 3 beforeElement = 46 # Find index index = listA.index(beforeElement) # Insert element at beforeElement listA.insert(index, element) print(listA)

Example 5: Adding an Element to the Beginning of a List

data = ['bmw', 'audi', 'mercedez'] data.insert(0, 'jaguar') print(data) 

Example 6: Inserting Dictionary into a List

main_dict = [, ] new_dict = main_dict.append(new_dict) print(main_dict)
