Oh look, I found a peanut! Let me get a 50lb sledgehammer to crack it
Please do not use eval to retrieve the function object. It's slow,
overkill, a bad habit to get into, and a security risk if the name you
are eval'ing comes from an untrusted source.
Instead, look the name up in globals() or locals():
py> def spam():
... return "NOBODY expects the Spanish Inquisition!"
py> name = "spam"
py> func = globals()[name]
'NOBODY expects the Spanish Inquisition!'
