Notes

Calling this magic from clients that do not implement standard input, such as the ipython notebook interface, will reset the namespace without confirmation.

Examples

We first fully reset the namespace so your output looks identical to this example for pedagogical reasons; in practice you do not need a full reset:: In [1]: %reset -f Now, with a clean namespace we can make a few variables and use ``%reset_selective`` to only delete names that match our regexp:: In [2]: a=1; b=2; c=3; b1m=4; b2m=5; b3m=6; b4m=7; b2s=8 In [3]: who_ls Out[3]: ['a', 'b', 'b1m', 'b2m', 'b2s', 'b3m', 'b4m', 'c'] In [4]: %reset_selective -f b[2-3]m In [5]: who_ls Out[5]: ['a', 'b', 'b1m', 'b2s', 'b4m', 'c'] In [6]: %reset_selective -f d In [7]: who_ls Out[7]: ['a', 'b', 'b1m', 'b2s', 'b4m', 'c'] In [8]: %reset_selective -f c In [9]: who_ls Out[9]: ['a', 'b', 'b1m', 'b2s', 'b4m'] In [10]: %reset_selective -f b In [11]: who_ls Out[11]: ['a']
