Specification code:

Python uses forced indentation to make the code readable. Programs written in Python language do not need to be compiled into binary code. Python's author designed a very strict grammar, so that bad programming habits (such as the next line of a statement is not indented to the right) cannot be compiled. One of the most important items is Python's indentation rules.

One difference from most other languages (such as C) is that the boundary of the module is completely determined by the position of the first character of each line (while C uses a pair of curly braces to clearly define the boundary of the module, regardless of the position of the characters).
