Here is another option. Look at the InteractiveConsole class. When you make a change, run the command: >>> changed Your subclass of InteractiveConsole catches it and does not send it to the compiler. Instead, it closes and reruns the entire session so far. Or, just the imports and definitions, which you have to detect by hand. This is probably the hard way. -- http://mail.python.org/mailman/listinfo/python-list

You can use reload, as Ben explained. Be aware though that this might introduce subtle bugs. I personally prefer to write small test-scripts & simply execute them. If you absolutely need to go interactive, you might consider using python -i script.py to drop to the prompt after the script has been executed.

A Python ‘import’ is conceptually two steps: execute the module, then bind the objects that were created to names in a namespace. The import mechanism has a short-cut: if the module has already been imported by this Python VM, the module isn't executed again, and the existing objects are simply re-used with new bindings as necessary. What you want is to specifically request the module to be re-executed to re-create the objects again, and re-bind the existing name bindings to the objects that result. >>> help(reload) -- \ “I hope that after I die, people will say of me: ‘That guy sure | `\owed me a lot of money’.” —Jack Handey | _o__) | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list
How to re-import a function from a module?
Hi, I have the following small problem. I run Python interactively. In the beginning of the run I import many functions from many modules. Than I execute some commands and notice that one of the imported functions contains a mistake. I open another terminal in which I open the file with the problematic function and correct the function. However, the Python does not see my changes. It still uses the old version of the function. In principle I could close the Python session and reopen it again and import all functions agane. But it does not seem to be a convenient solution. Is there a way to force Python to re-import the function, i.e. to force it to use the new version of the function? Thank you in advance. -- http://mail.python.org/mailman/listinfo/python-list
