查找了几个文件读取的写法,整理如下:

去除换行符
for line in file.readlines(): line=line.strip('\n')

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+'
