e correct answerWhat will be the output of the following Python code?m=10n=20def update():    global n    m=45    n=56update()print(m)print(n)

The output of the Python code will be:

10 56

Here's the step by step explanation:

1. The variables m and n are initially set to 10 and 20 respectively.
2. The function update() is defined. Inside this function, the global keyword is used to indicate that the variable n referred to here is the global variable n. The variables m and n are then set to 45 and 56 respectively. However, the change to m only applies within the function, because m is not declared as a global variable.
3. The function update() is called. This changes the global variable n to 56, but the global variable m remains 10 because the change to m in the function does not affect the global variable m.
4. print(m) prints the global variable m, which is 10.
5. print(n) prints the global variable n, which is 56.
