argmin() and argsort()

[PythonNewbie]

I think it has to do with what argsort() returns. For example,

import numpy as np

k = 1

x = np.array([0, 1, -1, 4, 2])
y = np.array(['a', 'b', 'c', 'd', 'e'])

indx_argmin = x.argmin()
indx_argsort = x.argsort()[:k]

print(indx_argmin, y[indx_argmin])
print(indx_argsort, y[indx_argsort])

outputs

Output:
2 c
[2] ['c']

Apparently they are not the same.

How to use argsort() or any other method to obtain the same results as argmin() when k = 1?
