| 297 | will only list functions and strings, excluding all other types of |
| 298 | variables. To find the proper type names, simply use type(var) at a |
| 299 | command line to see how python prints type names. For example: |
| 300 | |
| 301 | :: |
| 302 | |
| 303 | In [1]: type('hello')\\ |
| 304 | Out[1]: <type 'str'> |
| 305 | |
| 306 | indicates that the type name for strings is 'str'. |
| 307 | |
| 308 | ``%who`` always excludes executed names loaded through your configuration |
| 309 | file and things which are internal to IPython. |
| 310 | |
| 311 | This is deliberate, as typically you may load many modules and the |
| 312 | purpose of %who is to show you only what you've manually defined. |
