python array,_ code example

Example 1: python array[:

import array as arr

numbers_list = [2, 5, 62, 5, 42, 52, 48, 5]
numbers_array = arr.array('i', numbers_list)

print(numbers_array[2:5]) # 3rd to 5th
print(numbers_array[:-5]) # beginning to 4th
print(numbers_array[5:])  # 6th to end
print(numbers_array[:])   # beginning to end

Example 2: how to make an array python

#arrays and lists are different
#numpy arrays are faster
this_is_a_list = [1, 2, 3]
import numpy #is you do not have it do pip install numpy
this_is_an_array = numpy.array([1, 2, 3])
