How to Import and extract elements from a list of arrays saved as a text file in python-CodePudding

I have a .txt file, which is a list of arrays. I want to import that file and extract elements of that list of arrays and work with them. when I use

with open('filename.txt') as f:
        list1 = eval(f.read())

which works well when I want to import a list of numbers, does not work when the elements are arrays. It gives

NameError: name 'array' is not defined

Problem is perhaps with the eval() function not working well with arrays? Could you help me import this list of arrays?

CodePudding user response：

If the file content is, for example:

array([1,2,3])

...then...

from numpy import array

with open('filename.txt') as f:
    a = eval(f.read())
    print(a)
    print(type(a))

...will produce...

[1 2 3]
<class 'numpy.ndarray'>
