Convert strings within an array to list in Python-CodePudding

I want to convert the array A containing string elements to list. But I am running into error while using split(). I present the expected output.

import numpy as np
from numpy import nan
A=np.array(['[1]', '[2]',  '[3]', '[4]', '[5]'])
A.split()
print(A)

The error is

in <module>
    A.split()

AttributeError: 'list' object has no attribute 'split'

The expected output is

array([[1], [2], [3], [4], [5]])

CodePudding user response：

I think this should work

A=np.array(['[1]', '[2]',  '[3]', '[4]', '[5]'])
output = [[int(a.strip("[|]"))] for a in A]
print(output)

[[1], [2], [3], [4], [5]]

if you prefer just an list, instead of a list of list

A=np.array(['[1]', '[2]',  '[3]', '[4]', '[5]'])
output = [int(a.strip("[|]")) for a in A]
print(output)

[1, 2, 3, 4, 5]
