问题描述
我需要获取文本文件中短语的行号.这句话可以是:
I need to get the line number of a phrase in a text file. The phrase could be:
the dog barked
我需要打开文件,搜索该短语并打印行号.
I need to open the file, search it for that phrase and print the line number.
我在 Windows XP 上使用 Python 2.6
I'm using Python 2.6 on Windows XP
这就是我所拥有的:
o = open("C:/file.txt")
j = o.read()
if "the dog barked" in j:
print "Found It"
else:
print "Couldn't Find It"
这不是家庭作业,它是我正在进行的项目的一部分.我什至不知道如何获得行号.
This is not homework, it is part of a project I am working on. I don't even have a clue how to get the line number.

if lookup in line:
print 'found at line:', num
