Read mode ('r'): This mode is used to read an existing file. Write mode ('w'): This mode is used to write to a file. It will create a new file if the file does not exist, and overwrite the file if it does exist. Append mode ('a'): This mode is used to add new data ...
大多数时候，有必要将内容直接从JupyterNotebook中添加到python脚本或文本文件中。可以直接通过在代码之前添加writefile命令来导出单元内容，而不是复制所有内容并创建一个新文件。注意，命令前面的double %表示将导出单元的全部内容。因为已经用一些内容创建了这个文件，所以它显示了“OverwritemyCode.py”。指定它将用上面...
