From the random numpy list, I want to round only the numbers that are in the index of padInputs. The following code is something that I am trying but doesn't work. What would be a workaround?
padInputs = [0, 2, 7, 8]
random = np.random.rand(13)
for padInput in padInputs:
np.around(random[padInput])
For example,
Input
[0.87720789, 0.88194004, 0.06039337, 0.13874861, 0.85552875]
Output
[0.87720789, 1, 0, 0.13874861, 0.85552875]
Try this way:
random[padInputs] = np.around(random[padInputs])
Note that this will round without decimals, you can pass it as an argument to round in the following way:
random[padInputs] = np.around(random[padInputs], decimals=2)
Problem in your code is you have to assign result back to array as np.around is not in memory function.
like
for padInput in padInputs:
random[padInput] = np.around(random[padInput])
random
array([1. , 0.53206402, 1. , 0.18129529, 0.71238687,
0.92995779, 0.21934659, 0. , 1. , 0.26042076,
0.76826639, 0.82750894, 0.35687544])
but it should be replace by one line as @Bruno define in his answer.
The following one-line piece of code can replace your for loop and does exactly what you want
np.put(random, padInputs, np.around(random))
