1. Single Leading Underscore: _var
The underscore prefix is meant as a hint to another programmer that a variable or method starting with a single underscore is intended for internal use. This convention is defined in PEP 8.
  
2. Single Trailing Underscore: var_
In summary, a single trailing underscore (postfix) is used by convention to avoid naming conflicts with Python keywords. This convention is explained in PEP 8.

3. Double Leading Underscore: __var
A double underscore prefix causes the Python interpreter to rewrite the attribute name in order to avoid naming conflicts in subclasses.
