Question

Hi i'd like to get a source code in Python.

/*

Use a mask to multiply all values below 100 in the following list by 2:

>>> a = np.array([230, 10, 284, 39, 76])

Repeat this until all values are above 100. (Not manually, but by looping) Then, select all values between 150 < a < 200.

*/

Thank you

OUTPUT :

CODE :

import numpy as np
#Given numpy array
a = np.array([230, 10, 284, 39, 76])
#Find the mask for all elements less than 100
mask = (a<100)
#Keep checking if length of mask is greater than zero
while sum(mask)>0:
#Multiply masked elements by 2
a[mask] = a[mask]*2
#Find mask again
mask = (a<100)
#Select elements such that 150<a<200
print(a[a>100][a<200])
