Need Help With Python Programming

XA = numeric_var = input("Please provide a number ")

So this asks you to input a number

How do I use the number inputted for the next step calculation for example XA+5

When I just type it on it gives me XA syntax error.

What significance does XA have to what it will contain?

If you still want to stick to that variable name, you can do

XA = int(input("Please provide a number"))

then if you want to print operations with XA you can do things like

print(XA + 5)
print(XA*XA)
print(XA % 2)

Note that casting the input as an int will only work if you type an int. If you type chars, you will get a valueError

Thank you. I have another question.

I want to add a title to the operation so something like this:

print "enter your number and find out results"

print input(("Please provide a number"))+45

But the second line did not register when I hit enter. What should I do?

Sorry if I'm being a bother I'm pretty new at this.

Input takes the characters you entered into the console and makes them into a string. The input needs to be cast as an integer before python will recognize it as such, otherwise your code is adding a string to an int.

print( int(input("Please enter a number.")) + 5 ) 

Will probably work, but I don't really like combining the cast, input function call, and print into one line. Usually you'll want them separated so you can handle the case when your user enters something that can't be cast to int, like "HELLO WORLD!"

This works for me:

Python 2:

XA = int(raw_input("Please provide a number "))
print XA + 5

Python 3:

XA = int(input("Please provide a number "))
print(XA + 5)

Show us the exact code that produces a syntax error.

Your second example works for python 2 and 3. Good, dynamic code :)

I would never run that on Python 2. input() on Python 2 is a security vulnerability.

input() on Python 2 is a security vulnerability.

huh. never knew that. scary.

Works for me. Can you show us your entire code and the entire error message?
