Python List Vs Array

# Arrays Vs Lists

• Arrays need to be declared. Lists don’t
• Arrays can store data very compactly
• Arrays are great for numerical operations

import array

# Array (stores single data type)

array.array('i', [1, 22, 30, 44, 51]) # integer

array.array('d', [2.5, 3.2, 3.3]) # float

array.array('u', ['a', 'b', 'c']) # unicode

#List

ll = ['abc', 10, ['a', 'b', 'c'], (1,2,3)] # List can store anything 

import numpy as np

# Numpy Array (it can store various data types)

array_2 = np.array(["numbers", 3, 6, 9, 12])

print (array_2)

print(type(array_2))
