General print를 로그파일로 생성하기 (log출력 Redirection)

import sys

class Tee(object):
    def __init__(self, *files):
        self.files = files
    def write(self, obj):
        for f in self.files:
            f.write(obj.encode('utf-8'))

if __name__ == "__main__":
    f = open('logfile.txt', 'w')
    original = sys.stdout
    sys.stdout = Tee(sys.stdout, f)
    print "test"  # This will go to stdout and the file out.txt

    #use the original
    sys.stdout = original
    print "This won't appear on file"  # Only on stdout
    f.close()

위 코드는 logfile.txt를 만들고 "test"를 그 곳에 출력 (log출력 리다이렉션)합니다.
