Explain nested if—–else statement

Answer»

There may be a situation when you want to check for another condition after a condition resolves to true. In such a situation, you can use the nested if construct. In a nested, if construct, you can have an if…elif…else construct inside another if…elif… else construct. 

Syntax:

The syntax of the nested if…elif…else construct may be:

if expression1:

statement(s)

if expression2:

statement(s)

elif expression3:

statement(s)

else

statement(s)

elif expression4: statement(s) else:

statement(s)

Example:

# !/usr/bin/python if var < 200:

print “Expression value is less than 200”

if var==150:

print “=150”

elif var = =100:

print “=100”

elif var ==50:

print “=50”

elif var < 50 :

print “Expression value is less than 50”

else :

print “Could not find true expression”
