从文本文件中检索随机预格式化的文本 [英] Retrieve randomly preformatted text from Text File

问题描述

我正在编写一个python脚本，以获取位于文本文件中的格式为StartTime="mm/dd/yyyy hh:mm:ss:ccc"和EndTime="mm/dd/yyyy hh:mm:ss:ccc"的字符串.

I am writing a python script to get a string formatted as StartTime="mm/dd/yyyy hh:mm:ss:ccc" and EndTime="mm/dd/yyyy hh:mm:ss:ccc" located in a text file.

所以我继续搜索StartTime和Endtime，但是如何获取(="mm/dd/yyyy hh:mm:ss:ccc")之后的内容?当我得到StartTime和EndTime字符串时，我想将它们保存在具有功能saveIntoFile(File, textToSave)的另一个文本文件中，但我想我自己就可以处理这一部分.

So I proceed to search for StartTime and Endtime but how can I get what's after (="mm/dd/yyyy hh:mm:ss:ccc") ? When I get the StartTime and EndTime strings I want to save them in another text file with a function saveIntoFile(File, textToSave) but I think I'll be able to deal with this part myself.

def getTimeCode(File) :
    fopen = open(File, 'r')    
    text = fopen.read()
    for t in text :
        if t == "StartTime" :
            #what should I do now ?
        if t == "EndTime" :
            #what should I do now ?

def saveIntoFile(filename, textToSave):

推荐答案

import re

def getTimeCode(fn):
    with open(fn, 'r') as f:
        for line in f:
            m = re.search(r'(\w)="(\d\d/\d\d/\d\d\d\d \d\d:\d\d:\d\d:\d\d\d)"', line)
            if m:
                if m.group(1) == 'StartTime':
                    # do something with m.group(2)
                elif m.group(1) == 'EndTime':
                    # do something with m.group(2)
                else:
                    # m.group(1) unknown
