Leading white space at the beginning of the logical line is called indentation.

Indentation

• Leading white space at the beginning of the logical line is called indentation.

• Python programs get structured through indentation, i.e. code blocks are defined by their indentation.

• All statements with the same distance to the right belong to the same block of code, i.e. the statements within a block line up vertically.

• If a block has to be more deeply nested, it is simply indented further to the right.

• For example –

age = int(input('How old are you? '))

if age < = 2:

print(‘Infant’)

Here the line is indented that means this statement will execute only if the if statement is true



String Operations

• String is collection of characters.

  In python it is possible to perform the concatenation and repetition operations on strings using the operators like + and *.

For example

>>>str1="Hello"

>>> str2="friend"

>>> str1+str2 'Hellofriend'

>>> "welcome"*2

'welcomewelcome'
