## Learn Python NumPy #3 – Array Math Operations

In this video we’ll cover NumPy Math operations that we can do on Arrays.
The full list of universal functions that I mentioned in this video can be found here:
https://docs.scipy.org/doc/numpy/reference/ufuncs.html#available-ufuncs

In this video we’ll cover:
-NumPy Array Functions
– How to add numpy Arrays
– How to subtract, divide, multiply numpy arrays,
– Take square roots of NumPy arrays
– Linear operations on NumPy arrays
-Talk about vectorization and the alternative python for loops

Code from this video:
import numpy as np

ListA = [1,2,3,4]
ListB = [-1,2,4,6]

A = np.array(ListA, dtype=np.int32)
B = np.array(ListB, dtype=np.int32)

print(A)

ListA2 = []
for element in ListA:
element = element +1
ListA2.append(element)

print(ListA2)

print(A+1)
print(A+B)
print(A-B)
print(A*B)
print(A/B)
print(np.sqrt(A))
