Conditional Statements

Conditional expressions and conditional constructs are features ofa programming language, which perform different computations or actions depending on whethera programmer-specified Boolean condition evaluates to true or false.

If Statements

Syntax:

if expression:
 statement(s)

Example:

x=15

if x>0:

 print('Positive Value..")

If-else Statements

Syntax:

if expression:
     statement(s)
else:
     statement(s)

Example:

age=27
if age>18:
 print('You can drive')
else:
 print('you can not drive)

If-else if-else Statements

Syntax:

 if expression:
           statement(s)
    elif expression:
           statement(s)
    else:
           statement(s)

Example:

X=15
ifx>0:
     print('Positive Value..')
elif x<0:
     print('Negative Value..)
else:
      print('value is zero')

Nested if Statement

Syntax:

if expression:
      statement(s)
      if expression:
             statement(s).
       else:
             statement(s)
else:
       statement(s)

Example:

x=15
If x>0
          print(Positive Value)
         if 10:
                    print("Value is less then 10)
          else
                    print(Value is more than 10)
elif x<0
          print('Negative Value)
else:
          print('value is zero')
