Python Parse lines of input file
提问by Legen Waitforit Dary
Im a recent graduate who has made some contacts and trying to help one with a project. This project will help evolve into something open source for people. So any help I can get would be greatly appreciated.
我是一名应届毕业生，已经建立了一些联系并试图帮助一个项目。该项目将有助于演变为人们的开源项目。所以我能得到的任何帮助将不胜感激。
Im trying to parse out certain items in a file I have succeeded in parsing out the specific items. I now need to figure out how to attach all the remaining data to another variable in an organized way for example.
我正在尝试解析文件中的某些项目，我已成功解析出特定项目。例如，我现在需要弄清楚如何以有组织的方式将所有剩余数据附加到另一个变量。
file=open("file.txt",'r')
row = file.readlines()
for line in row:
if line.find("Example") > -1:
info = line.split()
var1 = info[0]
var2 = info[1]
var3 = info[2]
remaining_data = ????
^^^^^^^^^^is my sample code already doing 90% of what i need. I want to get the remaining_data to all go into that variable line by line for.
^^^^^^^^^^ 是我的示例代码已经完成了我需要的 90%。我想让剩余的数据逐行进入该变量。
print remaining_data
output:remaining_data{
line 1 of data
line 2 of data
line 3 of data
line 4 of data
}
how can I get it organized and going in like that line by line?
我怎样才能像这样一行一行地组织起来？
回答by Meitham
by using a slice
通过使用切片
remaining_data=info[3:]
If you need the indices you could do
如果你需要索引，你可以做
for i, line in enumerate(info[3:]):
print("{}: {}".format(i, line))
回答by cmd
remaining_data = []
for line in open("file.txt",'r'):
if line.find("Example") > -1:
info = line.split()
var1 = info[0]
var2 = info[1]
var3 = info[2]
remaining_data.append(' '.join(info[3:]))
at the end of the loop, remaining data will have all lines with out the first 3 elements
在循环结束时，剩余的数据将包含所有行而不包含前 3 个元素
