How to remove \n at the end of each value?

I want to make the input such that the user will type a separate number on each new line. I managed to put together this code

def str2arr(str):
    arr = []
    for line in str:          
        arr.append(str.replace('\n', ''))
    return arr
import sys
a = sys.stdin.readlines()
print(a)

It is working nearly as I would like to, but the output looks like

['6543\n', '6543\n', '7654\n']

Is there a clever way to remove the \n? And also, will I even get an usable integers using this method?

Thank you guys in advance.

You could use

a = ['6543\n', '6543\n', '7654\n']
integers = list(map(int, a))
print(integers)
# [6543, 6543, 7654]

Have a look at string.strip. That should provide the expected result.

You'll then have to call int() on each of the entries in the list.

Example:

>>> t = ['6543\n', '6543\n', '7654\n']
>>> [int(x.strip()) for x in t]
[6543, 6543, 7654]
