python array multidimensional code example

Example 1: how to create multidimensional array in python using numpy

from numpy import *
array = array([[1,2,3,4],[3,4,2,5]])

## if want you can print it 
print(array)

Example 2: 2d array python

array = [[value] * lenght] * height

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

print(array)

Example 3: 2d array python3

# 5x6, 2-d array of booleans using list comprehension:

matrix = [[False for col in range(6)] for row in range(5)]

# 6x5, 2-d array of banana's using list comprehension:

matrix = [['banana' for col in range(5)] for row in range(6)]

Example 4: two dimensional array python

# Creates a list containing 5 lists, each of 8 items, all set to 0
w, h = 8, 5;
Matrix = [[0 for y in range(h)] for x in range(w)] 

Matrix[0][0] = 1
Matrix[0][6] = 3 # error! range... 
Matrix[6][0] = 3 # valid
