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

如果你想要第一行,然后你想在文件上执行一些操作,这个代码将有所帮助.

with open(filename , 'r') as f:
    first_line = f.readline()
    for line in f:
            # Perform some operations

Answer 4

f = open(fname).readlines()
firstLine = f.pop(0) #removes the first line
for line in f:
    ...

Answer 5

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
