在Python文件中读取行时跳过第一行 [英] Skip first couple of lines while reading lines in Python file

问题描述

我想在阅读文本文件时跳过前17行。

I want to skip the first 17 lines while reading a text file.

让我们说文件看起来像：

Let's say the file looks like:

0
0
0
0
0
0
0
0
0
0
0
0
0
0
0
0
0
good stuff

我只想要好东西。我正在做的是更复杂，但这是我遇到麻烦的一部分。

I just want the good stuff. What I'm doing is a lot more complicated, but this is the part I'm having trouble with.

推荐答案

使用切片，如下所示

with open('yourfile.txt') as f:
    lines_after_17 = f.readlines()[17:]

---

如果文件太大量加载内存：

---

If the file is too big to load in memory:

with open('yourfile.txt') as f:
    for _ in xrange(17):
        next(f)
    for line in f:
        # do stuff
