调用read_text()读取并以字符串形式返回新文件的内容:'Hello, world!'。 请记住,这些Path对象方法只提供与文件的基本交互。更常见的写入文件的方式是使用open()函数和文件对象。在 Python 中读写文件有三个步骤: 调用open()函数返回一个File对象。 在File对象上调用read()或write()方法。 通过调用File对象上的...
StringIO就是在内存中创建的file-like Object,常用作临时缓冲。 • 写文件 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...

Suppose we have a bunch of strings that we have to write to a file. To write them line by line, we have to append an end-line character or \n at the end of each line so that the strings appear individually. Refer to the following code for the same. data = [ "Hello World!", ...
