if else Statement

Like other languages, Python features an else statement that can be paired with an if statement. The else statement identifies a block of code to be executed if the conditional expression of the if statement resolves to a false Boolean value. The syntax is what you expect:

if expression:
    expr_true_suite
else:
    expr_false_suite

Now the obligatory usage example:

>>> username = "john"
>>> password = "123"
>>> if username == "john" and password =="123":
    print "Hello john"
    print "welcome to python"
else:
    print "access denied"

    
Hello john
welcome to python
>>> if username == "john1" and password =="123":
    print "Hello john"
    print "welcome to python"
else:
    print "access denied"

    
access denied
