[Python] how to change a list of floats to list of nearest integers

Question

I have a list of floats, and I want to convert those floats to their nearest decimals. I do not want to convert one element at a time. Is there any way to convert them at once?
E.g.
[1.34 , 5.67 , 3.456, 9.78 ]

to

[ 1,  6,  3, 10]

Answer 1

Numpy's round() function returns each element rounded to the given number of decimals. The default value of the number of decimals is 0. Then you can apply astype(int) to convert them to integers.

Here is an example:

>>> import numpy as np

>>> a = np.array([1.34,5.67,3.456,9.78])

>>> a

array([1.34 , 5.67 , 3.456, 9.78 ])

>>> np.round(a)

array([ 1.,  6.,  3., 10.])

>>> np.round(a).astype(int)

array([ 1,  6,  3, 10])

>>>
