make a 2d array python code example

Example 1: how to create 2d list in python

o=[]
for i in range(0,rows):
    x=[]
    for j in range(0,cols):
        x.append(0)
    o.append(x)
#if you use [[0]*cols]*rows all rows will become the same list
#so editing in one row will edit all rows

Example 2: 2d array python

array = [[value] * lenght] * height

//example
array = [[0] * 5] * 10

print(array)
