friends, how should I correct this?

Question

import numpy as np
import numpy_financial as npf
prices = [3869.47, 7188.46, 22203.31, 29391.78]
res = np.std(prices)
print(res)

Answer 1

The only difference is the variable name for the standard deviation.

Answer 2

That depends on what you're trying to do. Your code runs fine and outputs the standard deviation of the values in prices.

Answer 3

Answer 4

Simon Sauter Is there a difference with the code above and this one:

import numpy as np
import numpy_financial as npf
prices = [3869.47, 7188.46, 22203.31, 29391.78]
x = np.std(prices)
print(x)
