Python按行读取文件
查找了几个文件读取的写法,整理如下:
1、学习了:https://www.cnblogs.com/scse11061160/p/5605190.html
file = open("sample.txt") # 读取文件所在的路径
for line in file: # 按行读取文件
pass # do something
file.close()
2、学习了:https://blog.csdn.net/ysdaniel/article/details/7970883(推荐)
去除换行符
for line in file.readlines():
line=line.strip('\n')
3、学习了:https://www.cnblogs.com/feiyueNotes/p/7897064.html
mobile = Method.createPhone()
file = r'D:\test.txt'
with open(file, 'a+') as f:
f.write(mobile+'\n') #加\n换行显示
‘r’:读
‘w’:写
‘a’:追加
‘r+’ == r+w(可读可写,文件若不存在就报错(IOError))
‘w+’ == w+r(可读可写,文件若不存在就创建)
‘a+’ ==a+r(可追加可写,文件若不存在就创建)
对应的,如果是二进制文件,就都加一个b就好啦:
‘rb’ ‘wb’ ‘ab’ ‘rb+’ ‘wb+’ ‘ab+’
