Python new line:

In programming, it is a common practice to break lines and display content in a new line. This improves the readability of the output. Apart from that, you would frequently come across the new line character a lot while working with files.

Hence it is quite important that you understand how to add a new line and familiarise yourself with how the new line character works. This tutorial is aimed to do the same.

Newline character in Python:

In Python, the new line character “\n” is used to create a new line. When inserted in a string all the characters after the character are added to a new line. Essentially the occurrence of the “\n” indicates that the line ends here and the remaining characters would be displayed in a new line.

Code and Explanation:

str_1 = "Hire the top \n1% freelance developers" print(str_1) ‘’’Output - Hire the top 1% freelance developers’’’ 

As aforementioned, the character after the new line character is printed in a new line.
Different ways to implement this would include either adding it to string directly, or concatenating it before printing it. A common question that beginners have while learning how to apply a new line is — since we are adding it to a string — Why doesn’t Python print “\n” as it is? And how does it know that a new line must be added?

Well, the backslash (“\”) in the new line character is called an escape sequence. Escape sequences are used to add anything illegal to a string. This way Python understands that the following character is not a part of a string and executes it.

Multiline Strings:

Multiline strings are another easy way to print text in a new line. As the name suggests the string itself spans over multiple lines. These strings can be assigned by using either 3 double quotes or 3 single quotes. Python understands that the string is a multiline string and prints it as such.

Code and Explanation:

str_1 = """Hire the top 1% freelance developers""" print(str_1) '''Output - Hire the top 1% freelance developers''' 

In the above example, the string is printed in the same way as the information was passed.

Closing thoughts — Python new line:

Although both methods can be used in Python to add new lines I would recommend using the first method as it is the most commonly accepted method. Also, given Python has an in-built character that facilitates this it is best to utilize it.

However, please feel free to explore and understand how the multiline method works.

Print Newline in Python – Printing a New Line

Shittu Olumide

Working with strings or text data in programming frequently involves printing a newline. The end of a line is indicated by a newline character, which also advances the cursor to the start of the following line. Using the escape character \n , we can print a newline in Python.

Other programming languages may have different rules for printing newline characters. While some languages may have a built-in function or method to print a newline, others might use a different escape sequence.

In this article, we will explore the different ways to print a newline in Python. We will also discuss some interesting research findings about the usage of newline characters in code and its impact on readability and maintainability.

By the end of this article, you will have a better understanding of how to print a newline character in Python and how to write code that is easy to read and maintain.

How to Print a Newline Using the \n Escape Sequence

The simplest and most common way to print a newline character in Python is by using the \n escape sequence. For example, the following code will print two lines of text, with a newline character between them:

While using the \n escape sequence is straightforward and widely understood, it may not always be the best choice for improving code readability and maintainability. In particular, using multiple \n characters can make code harder to read and maintain, especially when dealing with long blocks of text.

How to Print a Newline Using the print() Function with the End Parameter

Another way to print a newline character in Python is by using the print() function with the end parameter.

By default, the print() function adds a newline character at the end of the output. But we can change this behavior by specifying a different string to be used as the end parameter.

For example, the following code will print two lines of text with a newline character between them, using the print() function:

print("Hello", end='\n') print("World") 

Code readability can be enhanced by using the print() function with the end parameter, which makes it clearer where the newline character is being added.

On the other hand, it might also make the code verbose and more challenging to read, particularly when working with lengthy blocks of text.

How to Print a Newline Using the join() Method with the split() Method

A more advanced way to print a newline character in Python is by using the join() method with the split() method.

The split() method is used to split a string into a list of substrings, based on a specified separator. The join() method is used to join the elements of a list into a single string, using a specified separator.

By splitting a string on the newline character and then joining it back together with a newline character separator, we can print multiple lines of text.

For example, the following code will print two lines of text with a newline character between them, using the join() method with the split() method:

text = "Hello\nWorld" lines = text.split('\n') print('\n'.join(lines)) 

By making the code clearer and more concise by combining the join() and split() methods, this improves code readability. But when printing multiple lines of text, especially when dealing with lengthy blocks of text, this may not always be the most effective or performant method.

How Does Using Newline Characters Affect Code?

Several studies have investigated the impact of newline characters on code readability and maintainability.

One study found that code with consistent and predictable newline characters was easier to read and understand, especially for novice programmers. Another study found that excessive use of newline characters, or inconsistent use of indentation and whitespace, could make code harder to read and understand.

It is important to use newline characters in a consistent and predictable way, based on the conventions and guidelines of the programming language.

Conclusion

In this article, we checked out three different ways we can print newline in Python, and also mentioned the importance of having well-formatted code using the newline character.

Python New Line and How to Python Print Without a Newline

Estefania Cassingena Navone

Welcome! The new line character in Python is used to mark the end of a line and the beginning of a new line. Knowing how to use it is essential if you want to print output to the console and work with files.

In this article, you will learn:

• How to identify the new line character in Python.
• How the new line character can be used in strings and print statements.
• How you can write print statements that don’t add a new line character to the end of the string.

Let’s begin! ✨

🔹 The New Line Character

The new line character in Python is:

It is made of two characters:

If you see this character in a string, that means that the current line ends at that point and a new line starts right after it:

You can also use this character in f-strings:

🔸 The New Line Character in Print Statements

By default, print statements add a new line character «behind the scenes» at the end of the string.

This occurs because, according to the Python Documentation:

The default value of the end parameter of the built-in print function is \n , so a new line character is appended to the string.

💡 Tip: Append means «add to the end».

This is the function definition:

Notice that the value of end is \n , so this will be added to the end of the string.

If you only use one print statement, you won’t notice this because only one line will be printed:

But if you use several print statements one after the other in a Python script:

The output will be printed in separate lines because \n has been added «behind the scenes» to the end of each line:

🔹 How to Print Without a New Line

We can change this default behavior by customizing the value of the end parameter of the print function.

If we use the default value in this example:

We see the output printed in two lines:

But if we customize the value of end and set it to » «

A space will be added to the end of the string instead of the new line character \n , so the output of the two print statements will be displayed in the same line:

You can use this to print a sequence of values in one line, like in this example:

💡 Tip: We add a conditional statement to make sure that the comma will not be added to the last number of the sequence.

Similarly, we can use this to print the values of an iterable in the same line:

🔸 The New Line Character in Files

The new line character \n is also found in files, but it is «hidden». When you see a new line in a text file, a new line character \n has been inserted.

You can check this by reading the file with .readlines() , like this:

with open("names.txt", "r") as f: print(f.readlines())

As you can see, the first three lines of the text file end with a new line \n character that works «behind the scenes.»

💡 Tip: Notice that only the last line of the file doesn’t end with a new line character.

🔹 In Summary

• The new line character in Python is \n . It is used to indicate the end of a line of text.
• You can print strings without adding a new line with end = , which is the character that will be used to separate the lines.

I really hope that you liked my article and found it helpful. Now you can work with the new line character in Python.
