make 2 dimensional 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
array = [[0] * 5] * 10
print(array)
Example 3: 2d array pytho
# 2D array that is 3x4 (3 columns, 4 rows)
# note that it is essentially an array of lists
arr = [
[11, 12, 5],
[15, 6, 10],
[10, 8, 12],
[12, 15, 8]
]
