一、 通过readline 逐行读取:
#--encoding:utf-8
with open("ha.conf","r",encoding='utf-8') as f:
print(f)
print(f.encoding)
strline = f.readline()
while strline:
print(strline)
print(f.tell())
strline = f.readline()
open函数返回一个文件对象。有name、mode 和 encoding 属性。
以上代码返回如下:
D:\Python34\python.exe E:/PycharmProjects/Day3/file_operation.py
<_io.TextIOWrapper name='ha.conf' mode='r' encoding='utf-8'>
utf-8
global 8
log 127.0.0.1 local2 38
daemon 54
maxconn 256 …………
读取第一行 global 后,f.tell() 返回 8 : global 加上 换行 7个字符。
二:
with open("ha.conf","r",encoding='utf-8') as f:
for line in f:
print(line)
