Python: Create a global variable from a string?

Question

Is there a way to create a global variable from a string? I know that you can make a variable from a string like so:

    string = 'hello'
    val = 10
    vars()[string] = val

Thus making hello a variable equal to 10. I do not know how to make that user input variable global however, this does not work:

    string = 'hello'
    val = 10
    vars()[string] = val
    eval("global " + string)

Answer 1

You can use the globals() function:

name = "hello"
globals()[name] = 10
