如何将命令提示符中的Python编码保存为文件？

我刚从Python34中的一本书中输入了一个运行命令提示符的例子.

但现在我想将此python程序保存为文件以供将来使用.由于我以前从未使用过命令提示符,我也在网上搜索,但大多数都无法回答.

谁能在这里展示解决方案？谢谢.

解决方法:

您可以使用%save在ipython中保存行：

用法：

%save [options] filename n1-n2 n3-n4 … n5 .. n6 …
Options:

-r: use ‘raw’ input. By default, the ‘processed’ history is used, so that magics are loaded in their transformed version to valid Python. If this option is given, the raw input as typed as the command line is used instead.

-f: force overwrite. If file exists, %save will prompt for overwrite unless -f is given.

-a: append to the file instead of overwriting it.

This function uses the same syntax as %history for input ranges, then saves the lines to the filename you specify.

It adds a ‘.py’ extension to the file if you don’t do so yourself, and it asks for confirmation before overwriting existing files.

If -r option is used, the default extension is .ipy.

In [1]: def foo():
   ...:     print("hello world")
   ...:     

In [2]: %save my_code 1
The following commands were written to file `my_code.py`:
def foo():
    print("hello world")


In [3]: cat my_code.py
# coding: utf-8
def foo():
    print("hello world")
