2d arrays using python numpy

import numpy as np

#create array of arrays
all_arrays = np.array([[10, 20, 30, 40, 50],
                       [60, 70, 80, 90, 100],
                       [110, 120, 130, 140, 150]])

#view array of arrays
print(all_arrays)

[[ 10  20  30  40  50]
 [ 60  70  80  90 100]
 [110 120 130 140 150]]

numpy make 2d array 1d

import numpy as np
  
ini_array1 = np.array([[1, 2, 3], [2, 4, 5], [1, 2, 3]])
  
# printing initial arrays
print("initial array", str(ini_array1))
  
# Multiplying arrays
result = ini_array1.flatten()
  
# printing result
print("New resulting array: ", result)
