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 islicewith open(fname) as f:    for line in islice(f, 1, None):        pass
