Deleting carriage returns caused by line reading

Question

I have a list:

Cat
Dog
Monkey
Pig

I have a script:

import sys
input_file = open(\'list.txt\', \'r\')
for line in input_file:
           


        

Answer 1

str.rstrip or simply str.strip is the right tool to split carriage return (newline) from the data read from the file. Note str.strip will strip of whitespaces from either end. If you are only interested in stripping of newline, just use strip('\n')

Change the line

 sys.stdout.write('"' + line + '",')

to

sys.stdout.write('"' + line.strip() + '",')

Note in your case, a more simplistic solution would had been

>>> from itertools import imap
>>> with open("list.txt") as fin:
    print ','.join(imap(str.strip, fin))


Cat,Dog,Monkey,Pig

or Just using List COmprehension

>>> with open("test.txt") as fin:
    print ','.join(e.strip('\n') for e in  fin)


Cat,Dog,Monkey,Pig
