It is perfectly all right if we write an entire if...else
construct within either the body of the if statement or the body of an else statement. This is called ‘nesting’of ifs.
Nested if...else
statements has ability to control program flow based on multiple levels of condition.
if expression1: statement(s) if expression2: statement(s) elif expression3: statement(s) else: statement(s) elif expression4: statement(s) else: statement(s)
var = 10 if var < 20: print "value is less than 20" if var == 15: print "Value is 15" elif var == 10: print "Value is 10" elif var == 5: print "Value is 5" elif var < 5: print "value is less than 5" else: print "Bye" print "Good bye!"
value is less than 20 value is 10 Good bye!
