Can you use the same variable in different functions?
Even though the same variable name is used in both functions, it holds a different value. That’s because variables in C are local to their functions: One function cannot change the value of a variable in another function, even if both variables sport the same type and name.
There are two easy ways to do this:
- Use a text editor, like Notepad, to paste the clipboard contents into a new document (or, say, into an email that you’re writing to someone)
- Paste the clipboard contents directly into a Lister (Edit / Paste) to create a new text file.

How can I share a variable between functions in Python?
But global variables should be avoided as much as possible. Since a is defined outside the function scope and before the functions are defined, you do not need to feed it as an argument. You can simply use a. Python will first look whether the variable is defined in the function scope, and if not, it looks outside that scope.

What happens when you assign a variable to a list in Python?
If you make your own variable called list, you won’t be able to access the builtin one anymore. Read up the concept of a name space. When you assign a variable in a function, you only assign it in the namespace of this function.
