How can I write this in one line? Help me 🥹

Question

for element in B:
if element:
C.append(A[i])
i +=1

Answer 1

C = [ element for element in B if element ]

read about list comprehension.

Answer 2

i, C = len(B), [A[_] for _ in range(len(B)) if B[_]]

Answer 3

import numpy
def elements_vector_true():
A, B = numpy.random.randint(10, size = 10), numpy.random.randint(10, size = 10)%2==0
print(f"Vector A: {A}")
print(f"Vector B: {B}\n")
i, C = 0, []
print("The vector A elements wich position of the vector B elements are true are:")
for element in B:
if element:
C.append(A[i])
i +=1
print(C)

elements_vector_true()
