f=open('a.txt','r') # 文件名 模式 1. 2. 二、文件模式 r ---只读模式:打开文件不存在的话,会报错;使用.write()方法时报错。 w---只写模式:打开文件不存在的话,会自动新建文件;会清空原来文件的内容;使用.read()方法时报错。 a---追加写模式:打开...
>>>f=open('x','w')>>>f.write('this\nis\nschool')#write(string)>>>f.close()>>>f=open('x','r')>>>f.read()#在这里直接f.read()读出的是不换行的一段字符。'this\nis\nschool'>>>f=open('x','r')>>>printf.read()#使用print语句将文件somefile-11-4.txt文件的真正内容显示出来...
read() >>> baconFile.close() >>> print(content) Hello, world! Bacon is not a vegetable. 首先,我们以写模式打开bacon.txt。由于还没有一个bacon.txt,Python 创建了一个。在打开的文件上调用write()并向write()传递字符串参数'Hello, world! /n'将字符串写入文件并返回写入的字符数,包括换行符。
