My background is C - system programming. Switching to Python with so much libraries and functionalities make it a little over whelming. I wrote a simple calculator that rhythms with code we normally write with C.
First I wrote a simple calculator function, very straight you can practice by changing if to switch statement
import os
def Calculation(a, b, operation):
if(operation=='+'):
return(a+b);
if(operation=='-'):
return(a-b);
if(operation=='*'):
return(a*b);
if(operation=='/'):
return(a/b);
Below is the similar to the main program of 'C'.
while(1):
print('Welcome to Sam''s Calculator \n')
print('Press Q any time to exit the calcultaor \n')
a = input('Please enter the first input = ')
b = input('Please enter the second input = ')
op= input('Please select the operation to be performed = ')
if(a=='Q'or a=='q' or b=='Q' or b=='q' or op=='Q' or op=='q' ):
print('Thank you for using Sam''s Simple calcultaor. Calculator is now exiting \n')
break
a = int(a)
b = int(b)
result= Calculation(a,b, op)
print("Result of the operation ",op," = ",result)
