Conditional Statement

Conditional Statement

• Conditional statement are used to execute a block of statement on the basis of some condition.

Python supports the usual logical conditions from mathematics:-

• Equals: a == b 
• Not Equals: a != b 
• Less than: a < b 
• Less than or equal to: a <= b 
• Greater than: a > b 
• Greater than or equal to: a >= b

1. If Statement

Example :-

             a = 33

             b = 200

             if  b > a:

                    print("b is greater than a") 

     

2. Elif Statement

• The elif  keyword is python way of saying "if the previous conditions were not true, then try this condition".

 Example :-

  

       a = 45

       b = 45

       if  b > a:

              print("b is greater than a")

       elif a==b:

              print("a and b are equal")

3. Else Statement

The else keyword catches anything which isn't caught by the preceding conditions.

Example :-
     
         a =  56
         b = 45
         if  b > a:
                print("b is greater than a")
         elif  a==b:
                print("a and b are equal")
         else:
                print("a is greater than b")
