Basic Structure of Python program

BASIC STRUCTURE OF A PYTHON PROGRAM

#addition of two number

a = 10

b = 20

c = a + b

print(c)

print(“Addition=“,c)

#check greater number between two

if a>b:

 print(“The value of a is greater”)

else:

 print(“The value of b is greater”)

Output:-

30

Addition=30

The value of b is greater
