调用open( )函数时把指示符改为“w”即write,就可以进行写文件。成功打开文件后用write( )方法来进行写入。 >>> f = open('c:\Users\Administrator\test.txt', 'w') >>> f.write('Hello, world!') >>> f.close() 1 2 3 更好的写法: with open('c:\Users\Administrator\test.txt', 'w') ...

Run code Powered By In this example, we opened a file called new_nlp_wiki.txt in write mode (the 'w' argument), which means that any existing contents of the file will be overwritten. We then called the write() method on the file object to write the string “New wiki entry: Chat...
write_f.write(data) #强调第二点:f=open(...)是由操作系统打开文件,那么如果我们没有为open指定编码,那么打开文件的默认编码很明显是操作系统说了算了,操作系统会用自己的默认编码去打开文件,在windows下是gbk,在linux下是utf-8。 这就用到了上节课讲的字符编码的知识:若要保证不乱码,文件以什么方式存的,...
在现代数据分析和网络爬虫的应用中,使用 Python 爬取网页表格中的内容已经成为一种常见的技术手段。尤其是通过 Visual Studio Code (VSCode) 进行开发,能够大大提高工作效率。本文将围绕在 VSCode 中使用 Python 爬取网页表格的过程进行详细记录,以便于后来者参考和学习。
path = 'data_1.txt' if not os.path.exists(path): print(f'{path} 不存在') with open(path, 'wb') as f: f.write(b'hello world!\r\n') f.read()程序运行后,会在程序目录下生成一个 data_1.txt 文件,文件内容如下:hello world! 不过在运行程序时会抛出异常,因为 wb 模式下并不支持读取...
