If you have to multiply a listing by a scalar in Python, then you are able to do one of many following:
Possibility 1 – Utilizing Checklist Comprehensions
li = [1,2,3,4]
a number of = 2.5
li = [x*multiple for x in li]
print(li)
Output: [2.5, 5.0, 7.5, 10.0]
Possibility 2 – Utilizing map()
li = [1,2,3,4]
a number of = 2.5
def multiply(le):
return le*a number of
li = checklist(map(multiply,li))
print(li)
Output: [2.5, 5.0, 7.5, 10.0]
Possibility 3 – Utilizing Lambda Features
li = [1,2,3,4]
a number of = 2.5
li = checklist(map(lambda x: x*a number of, li))
print(li)
Output: [2.5, 5.0, 7.5, 10.0]
Possibility 4 – Utilizing Numpy Arrays
import numpy as np
li = [1,2,3,4]
a number of = 2.5
arr = np.array(li)
arr = arr * a number of
li = arr.tolist()
print(li)
Output: [2.5, 5.0, 7.5, 10.0]
