Python中打开文本使用的是with语句，比如打开一个文件并读取每一行
with open(filename) as fp:
for line in fp:
# do something
为了同时读取多个文件，可以使用下面的代码
with open(filename1) as fp1, open(filename2) as fp2, open(filename3) as fp3:
for l1 in fp1:
l2 = fp2.readline()
l3 = fp3.readline()
# do something
稍微简介一点可以使用contextlib中的nested，有
from contextlib import nested
with nested(open(filename1), open(filename2), open(filename3)) as (fp1, fp2, fp3):
for l1 in fp1:
l2 = fp2.readline()
l3 = fp3.readline()
# do something
以上这篇python 同时读取多个文件的例子就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
