Question

I was astonished that a thing this simple has been troubling me. Below is the code

list = []
f = open("log.txt", "rb")  # log.txt file has line separated values, 


for i in f.readlines():
    for value in i.split(" "):
        list.append(value)

print list

The output is

['xx00', '\n', 'xx01in', '\n', 'xx01na', '\n', 'xx01oz', '\n', 'xx01uk', '\n']

How can I get rid of the new line i.e. ‘\n’?

Answer 1

If line-separated means that there is only one value per line, you don’t need split() at all:

with open('log.txt', 'rb') as f:
    mylist = map(str.strip, f)

In Python 3 wrap map() in a list().
