How to split numbers individually in python from a text file?

This question is somewhat the same about others but different on what I'm trying to interpret as i'm also new to python.

suppose that i have sample.txt:

123
456

321
780

both are separated by white space. but i wanted them to look like:

>> goal = '123456'
>> start = '456312'

and my start up code somehow looks like:

with open('input.txt') as f:
    out = f.read().split()
    print map(int, out)

which results to:

>> [123, 456, 456, 123]

which is different from what I''m trying to exert.

Splint on \n\n. (If this isn't exactly what you need, then modify to suit!)

>>> inp = '123\n456\n\n321\n780\n'
>>> [int(num.replace('\n', '')) for num in inp.split('\n\n')]
[123456, 321780]

One thing you can do is loop through the file line by line, and if the line is empty then start a new string in the result list, otherwise append the line to the last element of the result list:

lst = ['']

with open('input.txt', 'r') as file:

    for line in file:
        line = line.rstrip()
        if len(line) == 0:
            lst.append('')
        else:
            lst[-1] += line

lst
# ['123456', '321780']
