file.write('Hello, World!\n') file.write('This is a new line in the file.\n') print("File 'example.txt' has been written to.") 解释 打开文件: 使用open('example.txt', 'w', encoding='utf-8') 打开或创建一个名为 example.txt 的文件。
f.write(string) 将一个字符串写入文件,如果写入结束,必须在字符串后面加上"\n",然后f.close()关闭文件 四、文件中的内容定位f.read() 读取之后,文件指针到达文件的末尾,如果再来一次f.read()将会发现读取的是空内容,如果想再次读取全部内容,必须将定位指针移动到文件开始: f.seek(0) 这个函数的格式如下(...
