What keyword must be used within a function to modify a global variabl...
To modify a global variable from within a function, the keyword "global" must be used before the variable's name. This tells the interpreter that the variable being referred to is not a local one but the global instance. Without this keyword, any assignment to a variable with the same name within the function would create a new local variable instead of altering the global variable. This is an essential concept in programming as it helps avoid unintended consequences of variable shadowing, where a local variable hides a global variable of the same name, leading to confusion.
