Updating Variable from User Input

Question

I am trying to make a program which the user enters contact information which is than stored in a Google Sheets document. The user enters their input, through the phrase:

def add_phone():
    contact_phone = input("Please enter the contact's phone number: ")

I use this to set the contact_phone variable, which is defined at the top of the document by contact_phone = ''. The problem is that when I try to send this information to the Google Sheets document

def store_info(contact_phone):
    worksheet.append_row(contact_phone)

It says

Traceback (most recent call last):
  File "/Users/user/PycharmProjects/contactList/main.py", line 46, in <module>
    add_contact()
  File "/Users/user/PycharmProjects/contactList/main.py", line 19, in add_contact
    store_info()
TypeError: store_info() missing 7 required positional arguments: 'contact_fname', 'contact_lname', 'contact_phone', 'contact_email', 'contact_address', 'contact_birthday', and 'contact_notes'

As you can see I am using more variables than just contact_phone but the same problem applies with all variables used (contact_fname, contact_lname, etc.) I was wondering if there was any way to update the variable from '' to the inputted variable (phone number) before I reach this step, without stopping the code.

I have tried setting the variable to itself after the input is inputted by the user (contact_phone = contact_phone), but I have had no success.

Answer 1

I figured out the answer. I started by defining global variables in my input functions: global contact_phone (as suggested by user: martineau).

This didn't fix all of my problems though. I had one function that had all the steps, including the input functions and my function which sends/saves the information to the Google Sheet document. I realized that the variables wouldn't update until the function finished so I removed the Google Sheets function (which read the inputted variables) from the main function and called it on its own after I called my main function:

add_contact()
store_info()

This lets the variables update to what the user inputted when the function would end. Then my next function (store_info) would be able to read the inputted variables and send these updated variables to the Google Sheet document, allowing them to be whatever is inputted by the user.
