Print on single line python

How to print in one line in Python

In this post, we are going to learn how to How to print in one line in Python. by default print() statement print output in a newline.But In python3+ extra argument end=”” is introduced for print() function to print output without Newline.Instead of printing without a newline, we can add a special character or string with the help of the end=” parameter. To print a number without a newline or space, we have to pass end=” at end of the print() statement with or without space

1. Python2.X print without Newline

To print without newline in Python2.x We use comma(,) at end of the different print statements. Let us understand with the below example.

print "Hi there! Welcome", print "to devenum.com", print "Thanks For Visiting"

Hi there! Welcome to devenum.com Thanks for Visting

2. Python3.X print in one-line

In Python3.x print() function extra end parameter is introduced that helps to print without a newline. Instead of printing without a newline, we can add a special character or string with the help of the end=”” parameter. Let us understand with example. The end=”” parameter helped us print without a new line, but there is no space between the output strings. We can add special character space ” ” to get space between different string output.

import sys sys.stdout.write("Hi there!") sys.stdout.write("Welcome to devenum.com.Thanks for visting US")

Hi there!Welcome to devenum.Thanks for visting US

5. How to print numbers in one line without space Python

In this example we are printing number 1 to 10 in one line without space by using the end parameter of print statement.

num = int(input("Please Enter the value of n:")) for i in range(num): print(i, end="")

Please Enter the value of n:10 0123456789

6. How to Print a list without a newline in Python

Sometimes we have to print all elements of a list in one line in python. We have already understood the end=”” parameter in print statement. Now let us use it to print python list.

list = ["C#", 3, "Java", 6, 9,12,17] print('list elements :') for item in list: print(item, end=" ")

list elements : C# 3 Java 6 9 12 17

Summary

In this post, we have learned How to print in one line in Python with examples in python 3.x and python2.x.

How to Print in Same Line in Python?

Printing in the same line in Python can be achieved in several ways, including using the «end» parameter in the print() function to set it to an empty string, the sys.stdout.write() function to write to standard output without a newline character, or the «sep» parameter in the print() function to concatenate strings and print them without a separator. The most common way in Python 3 is to use the «end» parameter. Choose the method that best suits your specific use case and Python version.

Print without Newline in Python 2.x

In this section, we will be looking at how to print in the same line in the Python2.x version. Lets us understand this section using code.

The above code is written in Python2.x, in the code, we just print the strings using print statements, and at the end of each print statement, , is used to print all the print lines in the same line.

Note:
As mentioned the above code is written in Python2.x, but as per today’s date( 17 July 2022 ), we are working in Python3.x version, so if we write the Python2.x code in Python3.x, so it might not work. So, before writing the above code in Python, make sure that one should first installs Python2.x installer, and then run the above code.

Print without Newline in Python 3.x

Switching from Python2.x to Python3.x , we saw some minor changes appear in our print statement and Python3.x it becomes a more user-friendly and easy way to write syntax.

As it is predefined in the print statement, for every print statement it will automatically switch to a new line. But in this case, we must understand how to print in the same line.

So, for printing in the same line, we need to add a parameter in the print statement, that will help us to print in the same line.

• variable:
  Enter the variable that you want to print.
• end:
  It is an optional parameter. It specifies the last character after printing the string. By default, the end character is end = «\n» , i.e., a new line character. So, by default, it will always go to a new line after calling the print() function.

As mentioned, it is an optional parameter, so we can change it like if end = «-» , then the last character will be — .

To not want to introduce a new line, replace the end with a space ” “ .

Print without Newline in Python 3. x without Using «for» Loop

In this section, we will see how to print the content in a single line without using a for a loop. As far as we know that in a for loop, the print command runs for n times, then every time it will print the content in a new line, but if we use end = » » , then we print the content in a single line, but also we are using for loop in that case.

Now, without using for loop and end = » » , we will see how to print the content in the same line.

Note:
* is a positional argument that helps print your data in a raw format. We can use other methods to remove commands and brackets from the array, but using * is simpler and can solve the problem of unpacking them.

Print on the Same Line with Space Between Each Element

In the above, we have printed the strings in a single with a space between every string.

We know that in the print() statement, we have a parameter end , which specifies the last character after printing the variable content. So, if we pass the space » » , in the end, parameter, it will separate our string value with a space after every string.

Print on the Same Line without Space Between Elements

In the above, we have printed the strings in a single one with no space between every string.

We know that in the print() statement, we have a parameter end , which specifies the last character after printing the variable content. So, if we pass the empty string «» , in the end, parameter, it will separate our string value with an empty character after every string.

Print on the Same Line with Some Sign Between Elements

In the above, we have printed the strings in a single one with no space between every string.

We know that in the print() statement, we have a parameter end , which specifies the last character after printing the variable content. So, if we pass the hypen sign «-» , in the end, parameter, then it will separate our string value with a hyphen after every string.

Python print() Function by Default Ends with a Newline

As far now we have seen different cases of using print statements, and we have seen the end parameter also. end parameter explains the last character after printing the variable content.

By default, the end parameter has character \n which represents the new line character.

Conclusion

• To print in the same line, use the «end» parameter in the print() function and set it to an empty string.
• Use the sys.stdout.write() function to write to standard output without a newline character.
• Use the «sep» parameter in the print() function to concatenate strings and print them without a separator.

Python Print Without New Line – Print on the Same Line

Zaira Hira

The print function is an important function in Python, as it is used to redirect output to the terminal. The output can also be redirected to a file.

The print function, by default, prints on a new line every time. This is due to the definition of print() in the Python documentation.

Why does Python’s print function print on a new line by default?

In the snippet below, we can see that by default the value of end is \n . This means that every print statement would end with a \n . Note that \n represents a new-line character.

Let’s see an example of the print function.

Code Example:

# using Print with default settings print("This will be printed") print("in separate lines")

In the example above, lines would be printed separately due to the definition: end=’\n’ .

How to print on the same line in Python

Sometimes, we need to print strings on the same line. This is specially useful when we are reading files in Python. When we read files, we get a blank between lines by default.

Let’s see an example. We have a file named rainbow.txt with contents shown below:

fhand = open('rainbow.txt') for line in fhand: print(line) 

In the code above, we have used a file handler fhand to access the file. Next, we iterate through the lines using a for loop.

When we print the contents, the results are like this:

The extra blank line is due to the presence of \n at the end of each line in the file which moves the cursor to the next line. Finally the blank line gets added due to print function’s behavior as discussed in the last section.

Let’s say we want to remove these. To do that, we can make some changes. For this, we need to change the default behavior of print . We’ll see how to do that in detail in the coming sections.

Option #1 – How to modify the value of end in a print function

Let’s customize the value of end in the print function. We’ll set it to ‘ ‘ which is a space.

Code Example:

# Customizing the value of 'end' print("This is string 1 same line", end=' ') print("This is string 2 different line") 

Now we can see that instead of a new line (\n) we are telling the print function to add a blank character at the end.

We can also provide another character instead of a blank like this:

# Customizing the value of 'end' with a custom separator print("This is string 1 same line", end=';') print("This is string 2 different line") 

Usage: The above example is just a way to print on the same line with the separating character of your choice.

Let’s see another example. We can iterate through a list of items and print them on the same line with end = ‘ ‘ .

# iterating lists list_fruits = ['red','blue', 'green', 'orange'] for i in list_fruits: print(i, end = ' ') 

Option #2 – Remove whitespace using rstrip() in files

We can remove certain characters around a string using strip() . By default, every line in a file has «\n» at the end. As we are concerned with only the character on the right, we will use rstrip() which stands for right-strip. We’ll discuss an example of rstrip() next.

You can learn more about the strip() method in this blog post.

Back to our file printing example

Remember, we discussed a file printing example where extra lines were being printed:

Let’s modify the code a bit using rstrip() .

print("1. Removing extra blank line") fhand = open('rainbow.txt') for line in fhand: line=line.rstrip() print(line) print("\n") print("2. Printing all in the same line") fhand = open('rainbow.txt') for line in fhand: line=line.rstrip("\n") print(line, end = ' ') 

Output

First, we have removed the extra whitespace with rstrip() . In the next step we have removed the trailing line again with rstrip(«\n») and end=’ ‘ to get the output in a single line.

Wrapping up

We have seen how we can print in Python without a new line. We have also seen how we can print lines in a file without extra trailing lines. I hope you found this tutorial helpful.
