bookIndentation

Python is easy about rules, but indentation is one of the few rules Python requires to observe.

All lines in a simple Python program should start at character 0 in every line (no tabs or spaces before code).

HOWEVER, certain blocks of code should use Indentation. The most common blocks that require Intentation are: conditional statements, functions and loops (more on this in the following chapters).

Example of a valid code:


              
123

            
#Example of valid code:
print("Hello, world!")
print("What a beautiful day!")
copy

Below is example of invalid code, it will throw on error (feel free to try). When you try to execute this program you will see error "IndentationError: unexpected indent", this means you broke the Indentation rules and need to fix it to execute the program.


              
123

            
#Example of invalid code:
print("Hello, world!")
	print("What a beautiful day!")
copy

Please note that empty lines are simply ignored. Use empty lines to separate code into blocks (make it more readable).
