Conditions

if-else statements use True and False to determine whether a requirement has been met and then produce an output based on the result. The if keyword checks the requirements are met and then produce an output for example:

Input:

a = 20

b = 30

if  b > a:

     print("b is greater than a")

output:

b is greater than a

The elif keyword will try another condition if the previous conditions were not met, for example:

Input:

a = 20

b = 20 

if b > a:

    print("b is greater than a")

elif a == b:

    print("a and b are equal")

Output:

a and b are equal

The else keyword catches anything which isn't caught by the preceding conditions for example:

Input:

a = 50

b = 20

    print("b is greater than a")

elif a == b:

    print("a and b are equal")

else 

    print("a is greater than b")

Output:

a is greater than b
