name 'Map' is not defined

It seems like you are trying to use the built-in function `map()` in Python, but you have not imported it or defined it in your code.

To use `map()`, you can either import it at the beginning of your code using `from builtins import map`, or you can use it by explicitly calling it as `builtins.map()`.

Here is an example of using `map()` to apply a function to each element of a list:

def square(x):
    return x**2

my_list = [1, 2, 3, 4, 5]
squared_list = list(map(square, my_list))
print(squared_list)  # Output: [1, 4, 9, 16, 25]

I hope this helps! Let me know if you have any other questions.
