Python if,elif and else conditional statements

Conditional statements allow to execute logic based on a logic.If is used for defining conditional statements in Python.

It is defined using the keywords:

• if
• elif
• else

Following is a sample if statement

if True:
 print('this will print')
elif False:
 print('this will print')
else:
 print('this will not print')

notice that we have used indentation for nesting the blocks in the if and elif blocks

we normally use conditional expressions using operators in the if statement for comparison as:

x=1
if x==1:
 print('this will print')
elif  x==2:  
 print('this will print')
else:
 print('this will not print')

Commonly used Python conditional operators are:

• ==  equality
• != not equal
• > greater than
• < less than
• >= greater than equal to
• <= less than equal to

there are logical operators

• and
• or
• not
