Basic Programs

1) Hello Python

​

​

This is the most basic Python program. It specifies how to print any statement in Python.

In old python (up to Python 2.7.0), print command is not written in parenthesis but in new python software (Python 3.4.3), it is mandatory to add a parenthesis to print a statement.

2) Python program to do arithmetical operations

​

The arithmetic operations are performed by calculator where we can perform addition, subtraction, multiplication and division. This example shows the basic arithmetic operations i.e.

  • Subtraction

# Store input numbers:  

num1 = input('Enter first number: ')  

num2 = input('Enter second number: ')  

  

# Add two numbers  

sum = float(num1) + float(num2)  

# Subtract two numbers  

min = float(num1) - float(num2)  

# Multiply two numbers  

mul = float(num1) * float(num2)  

#Divide two numbers  

div = float(num1) / float(num2)  

# Display the sum  

print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))  

  

# Display the subtraction  

print('The subtraction of {0} and {1} is {2}'.format(num1, num2, min))
