如何使用python读取和处理日志文件

Question

对于这里的所有Python Gods，我如何从特定目录中读取多个.log文件（仅包含日志文件），并标记/打印出在Python中重复超过50次的错误/行？我似乎无法弄清楚。

# parselogfiles() uses a line index in every file to search for possible recurrence
def parselogfiles ():
    movefile()
    log_file_path = (moveto + '/*.log')
    files = glob.glob(log_file_path)
    for name in files: # 'file' is a builtin type, 'name' is a less-ambiguous variable name.
        try:
            with open(name) as f:
                sys.stdout.write(f.read())

        except IOError as exc:
            if exc.errno != errno.EISDIR:
                raise ""
