IPython %save magic error

Question

I'm trying to save a python file that I loaded into my IPython notebook with the %loadpy magic. When I try and save the file with %save settings.py I get the following error:

File `settings.py` exists. Use `%save -f 'settings.py' -f` to force overwrite

Then when I use %save -f 'settings.py' -f I get the error:

'-f' was not found in history, as a file, url, nor in the user namespace.

%save -f 'settings.py' yeilds the error '' was not found in history, as a file, url, nor in the user namespace. as well.

Any idea how to correctly save a .py file so that it overwrites the previous version? Thanks!

Answer 1

In [13]: %save -f settings.py 1-10 # saves lines 1 to 10 to settings.py
In [14]: %save? # Gives you the help on the save command


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

n1-n2, n3-n4 are ranges of lines that you want to save. n5, n6 are individual line numbers that you want to save. Add -f option to force save.
