读取文件中以\\ n结尾的行

Question

When I do

f = open("test.txt","r")
s = f.readline()
l = s.split[' ']

in which the input file has the content 2 3\\n . s has the value ['2', '3\\n'] . Is there a way to tell python that each line ends with a \\n and therefore it should not read it?

Contents of file:

3 2\n
#1###2#\n
****#**\n
##*###*\n
#******\n
#*#O##*\n

I will do other operations for the other lines. But I still need to get rid of \\n

Answer 1

The caveat here is that except for the literal '\\n' there is also an actual \\n at the end of each line (except for the last line, which only has the literal '\\n' ):

with open('test.txt') as f:
    print(f.readlines())
# ['3 2\\n\n', '#1###2#\\n\n', '****#**\\n\n', '##*###*\\n\n', '#******\\n\n', '#*#O##*\\n']

You need to call .strip with both the literal '\\n' and the actual \\n :

with open('test.txt') as f:
    lines = [line.strip('\\n\n') for line in f]

print(lines)
# ['3 2', '#1###2#', '****#**', '##*###*', '#******', '#*#O##*']
