Python - How to take user input and use that in function

Question

Please help me why on executing the below program an error coming on m variable

x=int(input("Enter first number"))
y=int(input("Enter second number"))

def multiplication():
 m=x*y
print("Multiplication result"m)

Have you followed any basic Python tutorial? – Ajeet Shah Jun 18 '16 at 06:26 — Ajeet Shah, Jun 18 '16 at 06:26

In Python 2, you should accept user inputs with raw_input(): Check this.

x=int(raw_input("Enter first number"))
y=int(raw_input("Enter second number"))

Please follow a proper indentation plan with python:

Also, you did not accept the variables while defining your function, and learn how to use print:

def multiplication(x, y):
    m = x * y
    print "Multiplication result: %d" % m

Finally, to call this function, use:

multiplication(x, y)

Thanks alot for your respobse! We can't take any user input and use that data in operation of function – Vaibhav Agrawal Jun 18 '16 at 06:43

I am actually to create a calculator. – Vaibhav Agrawal Jun 18 '16 at 06:58
I edited my answer, yes, you can take user input and pass it to function. In my answer, I am passing user inputs `x` and `y` to the function `multiplication`. Does that clarify your issue? – Ajeet Shah Jun 18 '16 at 06:59
Thanks a lot Now I got it the issue was with ' input' and when I replaced it with 'raw_input' it is working fine – Vaibhav Agrawal Jun 18 '16 at 07:06
`def multiplication(x, y): m = x * y print "Multiplication result: %d" %m ` In this `%d `is placeholder for numeric or decimal values but what is the use of `%m`?? Because when I am using only m it is showing error? – Vaibhav Agrawal Jun 18 '16 at 07:39
Please check the link i provided for `print` in python. Python accepts list of arguments in a tuple followed by `%` – Ajeet Shah Jun 18 '16 at 07:54
`% (m, n, o, etc)` or just for one argument, you can use `% m`. – Ajeet Shah Jun 18 '16 at 07:56

x=int(raw_input("enter first number"))
os=raw_input("Enter the sign of what you wanna do +,-,/,*")
y=int(raw_input("enter second number"))

You might consider editing your answer and add at least one line about what your program does. Also, you can write what your problem was in your question and how you solved your problem. You can also accept your own answer. – Ajeet Shah Jun 18 '16 at 14:48
Okay I am edited and will remember this forever Thankyou! – Vaibhav Agrawal Jun 18 '16 at 15:27
Better, you do rollback, earlier one was better. – Ajeet Shah Jun 18 '16 at 15:33

You can also do like this if you want to keep it in functions.

def input_function():
    x = int(raw_input("Enter first number"))
    y = int(raw_input("Enter second number"))
    return x,y


def multiplication():
    x,y = input_function()
    m = x * y
    print "Multiplication result", m

multiplication()

Or like this, in one function. But it doesn't look so pretty.

def multiplication(x,y):
    m = x * y
    print "Multiplication result",m


multiplication(int(raw_input('Enter first number')),int(raw_input('Enter second number')))

def r():
    v = int(input("voltage: "))
    i = int(input("current: "))
    resistance = v*i
    return(resistance,'ohms')

While this code may solve the question, [including an explanation](//meta.stackexchange.com/q/114762) of how and why this solves the problem would really help to improve the quality of your post, and probably result in more up-votes. Remember that you are answering the question for readers in the future, not just the person asking now. Please [edit] your answer to add explanations and give an indication of what limitations and assumptions apply. – Dharman Jul 22 '20 at 12:19
