    statement_2
    .....

In Python if .. else statement, if has two blocks, one following the expression and other following the else clause. Here is the syntax.

Syntax :

if expression :
    statement_1
    statement_2
    ....
  else : 
   statement_3 
   statement_4
   ....

>>> a=10
>>> if(a>10):
	print("Value of a is greater than 10")
else :
	print("Value of a is 10")
