Can I store slicers in a variable? (Pandas/Python) [duplicate]

Question

I'm just wondering if I can do something like:

df.loc['1990':'2000']

by doing something like:

my_slice = '1990':'2000' df.loc[my_slice]

What I've written doesn't work, but is there something similar that does?

Yes, but you don't write slices like that. You write slice('1900', '2000', None) instead.

What's the 'None' part? (can't find slice in the docs) Thanks!

@cjm2671 that's the step, just like the : notation - None is the default, so redundant. As for the docs: docs.python.org/2/library/functions.html#slice
