Python: Find index of minimum item in list of floats [duplicate]

python list floating-point minimum floating-point-precision

I would use:

val, idx = min((val, idx) for (idx, val) in enumerate(my_list))

Then val will be the minimum value and idx will be its index.

python list floating-point minimum floating-point-precision

You're effectively scanning the list once to find the min value, then scanning it again to find the index, you can do both in one go:

from operator import itemgettermin(enumerate(a), key=itemgetter(1))[0]

python list floating-point minimum floating-point-precision

Use of the argmin method for numpy arrays.

import numpy as npnp.argmin(myList)

However, it is not the fastest method: it is 3 times slower than OP's answer on my computer. It may be the most concise one though.
