Indentation

Indentation.

• Python uses indentation to define block of code , unlike other programming languages. Most of the programming languages like C, C++, Java use braces { } to define a block of code.
• A code block (body of a function, loop etc.) starts with indentation and ends with the first unindented line. It must be consistent throughout that block, otherwise it will give indenting error or may give a different result.

Example 1
This will result an indentation Error.

a_var=1

print  ‘Heading’.

If  a_var==1:

print  ‘Value is One’

else:

     print ‘Value is Not One’

Result

Example 2
Here Indentation is proper and It will not generate any Indentation Error.

a_var=1

print  ‘Heading’.

If  a_var==1:

     print ‘Value is One’

else:

     print ‘Value is Not One’

Result
