Indentation in Python 

Indentation is a Whitespace at the beginning of a code line.
·         Python does not know which statement to execute next or belongs to which block.
·         Without proper indenting the Python generating Indentation Error and the code will not get

            compiled.
·         Indentation telling to Python interpreter that the group of statements belongs to a particular block

            of code.
·         A block is a group of statements for a specific purpose, In  C, C++, Java uses braces { } for this.
·         All statements with the same distance to the right belong to the same code block.

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