Example:

for example, open any of your text editor(notepad/notepad++), then copy the code below

a = 9
b = 4
#Addition of numbers
add = a + b 
#Subtraction of numbers
sub = a - b 
#Multiplication of number
mul = a * b 
#Division(float) of number
div1 = a / b 
#Division(floor) of number
div2 = a // b 
#Modulo of both number
mod = a % b 
#Power
p = a ** b 
print results
print(add) 
print(sub) 
print(mul) 
print(div1) 
print(div2) 
print(mod) 
print(p) 

Save this file with test.py, then search your Command Prompt (.cmd) in your windows, open it, then type: python test.py, or python3 test.py.
