How to Print a Blank Line in Python?


Have you ever needed to print a blank line in your Python program? If so, you may be wondering how to do it. The good news is that it’s actually pretty straightforward!

We will go over the various ways to do this and discuss the pros and cons of each method.

There are four ways to print a blank line in Python:

1. Using the print() function with an empty string:

This is the most straightforward way to print a blank line. You simply call the print() function with an empty string as an argument, like this:

print("")
Code language: PHP (php)

The only downside to this method is that if you’re using it in a script, it will insert a blank line at the end of the output when the script is run.

2. Using the print() function with no arguments:

This is similar to the first method, but you don’t pass anything into the print() function, like this:

print()
Code language: PHP (php)

The advantage of this method over the first one is that it doesn’t insert a blank line at the end of the output when used in a script. However, it does insert a space instead of a blank line, which may or may not be what you want.

3. Using sys.stdout.write():

This method doesn’t actually use the print() function at all. Instead, it uses sys.stdout.write(), which writes a string to standard output without adding any trailing newline characters (like print() does). So, to print a blank line, you would use it like this:

sys.stdout.write("\n") # prints a blank line sys.stdout.flush() # forces stdout to flush so the blank line is printed immediately
Code language: Python (python)

This has the advantage of not inserting any unwanted spaces or newlines at the end of your output when used in a script, but it’s more complicated than either of the previous two methods.

4. Using multiple newline characters:

This is probably the easiest way to print a blank line, but it’s also less versatile than any of the other methods since you have to put as many new lines as you want between whatever you’re printing and where you want your blank line(s) to appear:

print("Hello world! ") # prints "Hello world!" followed by three blank lines
Code language: PHP (php)

This can be useful if you need to put multiple blank lines between things for visual purposes (e.g., for formatting), but if you only need one blank line, then any of the other methods would be better choices since they’re simpler and more flexible.

Conclusion:

There are four ways to print a blank line in Python: using the print() function with an empty string; using the print() function with no arguments; using sys.stdout.write(“\n”); or multiple newline characters. Each method has its own advantages and disadvantages, so choose whichever one best suits your needs! Thanks for reading!
