I need help in the Python in Finance course

Question

I am stuck in the Code repo: Bitcoin Project I did not come up with the expected code. Please help:
import numpy as np
import numpy_financial as npf # why do we need both np and npf?
#price for 2018-2021
bitcoin=[3869.47, 7188.46, 22203.31, 29391.78]
np.std(bitcoin)
print(bitcoin) # what am I missing? #this is the first instance of the code rep

Answer 1

1. financial functions are depricated in numpy. Therefore you need numpy_financial package to use them. Although it's not needed in this task, but further code will be added step by step in future lessons.

2. print(np.std(bitcoin))

Answer 2

Thanks so much! what do you mean by "Financial functions are depricated in numpy" please expain in simple terms
