从第2行读取文件或跳过标题行

Question

如何跳过标题行并开始从第2行读取文件？

Answer 1

with open(fname) as f:

    next(f)

    for line in f:

        #do something

Answer 2

f = open(fname,'r')

lines = f.readlines()[1:]

f.close()

Answer 3

如果要第一行，然后要对文件执行一些操作，此代码将很有帮助。

with open(filename , 'r') as f:

    first_line = f.readline()

    for line in f:

            # Perform some operations

Answer 4

如果切片可以在迭代器上工作...

from itertools import islice

with open(fname) as f:

    for line in islice(f, 1, None):

        pass
