Do you know what the use of python new line is? Python newline characters are used to indicate the end of a line and the beginning of a new line. It is important to know how to use it if you want to output the output to the console and work with the file.
In this article, you will learn the following how to identify a newline character in Python, how to use newline characters in strings and print statements. How to write a print statement that does not add a newline character to the end of the string. Let’s get started!
Newline character
The newline characters in Python are:
It consists of two characters:
- Backslash
- The letter n.
If you see this character in the string, it means that the current line ends at this point and a new line starts shortly thereafter.
You can also use this character in fstrings:
>>> print (f "Hello \ nWorld!")
A print statement newline character
By default, the print statement adds a new “behind-the-scenes” line character to the end of the string.
So:
This happens for the following reasons according to the Python documentation:
The default value of the end parameter of the built-in print function is \ n, so a newline character is added to the string.
Tip: Add means “add at the end”.
This is the definition of the function. Did you see what the value of the end is? It is of
is \ n. Therefore, this is added to the end of the string.
If you use only one print statement, you won’t notice because only one line is printed.
However, if you use multiple print statements per line in your Python script:
\ n has been added, so output Will be on separate lines “Behind the scenes” at the end of each line:
How to Print without line breaks
This default behaviour can be changed by adjusting the value of the end parameter of the print function.
If you use the default value in this example:
The output will be displayed in 2 lines:
However, if you adjust the value of the end, (end and set it to " ")a space will be added at the end of the string.
You can add a newline character \ n so that the output of two print statements is displayed on the same line:
You can use this to print a sequence of values on one line, as in the following example:
The output is:
Tip: Add a conditional statement to prevent the comma from being added to the last digit in the sequence.
Similar to iterable values can be printed on the same line:
Output is:
File line feed character
The newline character \ n is also in the file, but it is “hidden”. When a new line appears in the text file, the newline character \ n is inserted.
You can check this by reading the file with <file>.readlines(), like this:
with open("names.txt", "r") as f:
print(f.readlines())The output is:
As you can see, the first three lines of the text file end with a newline \ n characters that work “behind the scenes”.
Tip: Note that only the last line of the file does not end with a newline.
Conclusion
The newline character in Python is \ n. This is used to indicate the end of a line of text. You can print a string without adding a line break with end =.
Thus, this is the character used to separate the lines. We hope you loved reading this article and found it of some use. Now you’re ready to work with newline characters in Python. You can always contact us in case of any other doubts on our website.
