python 怎么读取当前目录下指定文件

Question

如题所述

Answer 1

读文本文件
input = open('data', 'r')
#第二个参数默认为r
input = open('data')

读二进制文件
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获取每行：
for line in file_object:
process line
