python 怎么读取当前目录下指定文件

input = open('data', 'r')

#第二个参数默认为r

input = open('data')

读冲旅带二进制文件

input = open('data', 'rb')

读取所有内容

file_object = open('thefile.txt')

try:

all_the_text = file_object.read( )

finally:

file_object.close( )

读固定字节

file_object = open('abinfile', 'rb')

try:

while True:

chunk = file_object.read(100)

if not chunk:

break

do_something_with(chunk)

finally:

file_object.close( )

读每行

list_of_all_the_lines = file_object.readlines( )

如果文件是文本文件，还可以直接遍历文件对象散芦获取每行：

for line in file_object:

process line

path = "d:/"

for root,dirs,files in os.walk(path):

dirs得到的是一个列烂丛庆郑碧表饥握，元素就是文件夹名
