python nested for loop zip

Question

I have the following list:

grid = [[0] *50 for n in range(50)]

I want to replace the values in grid (with 1) for each coordinate contained in the list:

area = [(30, 28), (27, 32), (32, 34), (43,23), (43, 2) ...] # Continues on

Is there any simple method that this can be done?

Your input is a 50x50 2D list, and your output is of an unknown dimension from what I see from here, can you explain on how you want to convert this — Devesh Kumar Singh

Hi Davesh. For example the value at grid[30][28] would be changed — Robert Garza-Altuna

And you have the values to which it will be changed to as well?, also what kind of coordinate is (43) or (23) ? — Devesh Kumar Singh

A simple for loop is what is needed.

for i,j in area:
    grid[i][j] = 1
