BinaryRecordFile.BinaryRecordFile根据索引进行工作,BikeStock.BikeStock类根据自行车ID进行工作,这是由BikeStock.BikeStock实例(其中存放一个字典,该字典将自行车ID与索引进行关联)进行管理的。 我们首先查看BikeStock.Bike类的class行与初始化程序,之后查看其中选定的几个BikeStock.BikeStock方法,最后将查看用于在BikeStock...

filename:代表你要访问的文件名 mode:这里代表你打开文件的模式,有 只读,写入,读写,追加等模式;默认为只读模式。 我们可以看下面的列表: 1、读模式 r 以只读方式打开文件。文件的指针将会放在文件的开头。这是默认模式 例子: 代码语言:javascript 代码运行次数:0 ...
Binary mode ('b'): This mode is used to read or write binary data, like images or audio files. Open a file in the write mode file = open('example.txt', 'w') # Write to the file file.write('Hello, World!') # Close the file ...
“an object exposing a file-oriented API (with methods such as read() or write()) to an underlying resource.” 文件对象分为3类: Text files Buffered binary files Raw binary files Text File Types 文本文件是你最常遇到和处理的,当你用open()打开文本文件时,它会返回一个TextIOWrapper文件对象: ...
