文本文件读取和打印数据 [英] Text File Reading and Printing Data

问题描述

我的文本文件MyText.txt

This is line 1
This is line 2 
Time Taken for writing this#      0 days 0 hrs 1 min 5 sec
Nothing Important
Sample Text

客观

要读取文本文件并查找文件中是否存在样本测试.如果存在，则打印写入文件所花费的时间(这是文件中已经存在的值)"

To read the text file and find if "Sample Test is present in the file. If present print the time taken to write the file(which is a value already inside the file)"

我的代码

with open('MyText.txt', 'r') as f:
    f.readline()
    for line in f:
        if 'Sample Text' in line:
            print "I have found it"
            f.seek(0)
            f.readline()
            for line in f:
                if 'Time Taken' in line:
                    print line
                    print ' '.join(line.split())
f.close()

代码运行正常.我的问题是，是否可以使此代码变得更好.考虑到我是python的新手，我相信会有更好的方法来编写此代码.任何人都可以建议使用其他/更快的方法.

The code is working fine. My question is if this code can be made even better . Considering I am new to python, I am sure there would be a better way to code this.Can anyone sugggest alternative/faster approach for this.

推荐答案

这应该有效.

with open('MyText.txt', 'r') as f:
  lineArr=f.read().split('\n')
  if 'Sample Text' in lineArr:
    timeTaken = [s for s in lineArr if "Time Taken" in s]
    print timeTaken[0]
