CALCULATOR

This post shows a simple calculator using python(2.7).It uses function for doing operations.

an example:for addition - def addition(x,y):

"This Function For Addition"

return x+y.

                                              This function reads 2 values from the main and returns the sum to 'c'..

   def addition(x,y):

"This Function For Addition"

return x+y

def substraction(x,y):

"This Function For Substraction" 

return(x-y)

def multiplication(x,y):

"This Function For Multiplication"

return(x*y)

def division(x,y):

"This Function For Division"

return(x/y)

print "Select A Operation"

print "1-> Addition"

print "2-> Substraction"

print "3-> Multiplication"

print "4-> Division"

choice=int(input("Enter A Choice(1,2,3,4):"))

#Main Program

if choice>4:

print "Sorry..... Please Enter A Valid Input (1,2,3,4)"

else:

a=float(input("Enter 1st number:"))

b=float(input("Enter 2nd number:"))

if choice==1:

c=addition(a,b)

print a,"+",b,"Is=",c

elif choice==2:

d=substraction(a,b)

print a,"-",b,"is =",d

elif choice==3:

e=multiplication(a,b)

print a,"*",b,"is =",e

elif choice==4:

f=division(a,b)

print a,"/",b,"is =",f
