    lines = sys.stdin.readlines()
    for i in range(len(lines)):
        lines[i] = lines[i].replace('\n','')
    #print lines

Thanks for the gist! I've used it to set up an alias to urlencode strings like so, maybe this is helpful to someone:

python3 -c 'import sys; from urllib.parse import quote; print(quote(sys.stdin.readlines()[0]))'

Most likely you don't want to remove all whitespace from the line, only the trailing newline

def read_in():
   return [x.rstrip('\n') for x in sys.stdin ]
