Python Syntax

Python Syntax Execute Python Syntax As we learned in the previous page, Python syntax can be executed by writing directly in the Command Line:

>>> print("Hello, World!")
Hello, World!
Or by creating a python file on the server, using the .py file extension, and running it in the Command Line:

C:\Users\Your Name>python myfile.py

Python Indentation Indentation refers to the spaces at the beginning of a code line.

Where in other programming languages the indentation in code is for readability only, the indentation in Python is very important.

Python uses indentation to indicate a block of code.

ExampleGet your own Python Server

if 5 > 2:
    print("Five is greater than two!")

Python will give you an error if you skip the indentation:

Example Syntax Error:

if 5 > 2:
    print("Five is greater than two!")

The number of spaces is up to you as a programmer, the most common use is four, but it has to be at least one.

Example

if 5 > 2:
    print("Five is greater than two!")
if 5 > 2:
        print("Five is greater than two!")

You have to use the same number of spaces in the same block of code, otherwise Python will give you an error:

Example Syntax Error:

if 5 > 2:
    print("Five is greater than two!")
        print("Five is greater than two!")
