Example Usage for Drop-in List Replacements¶

# remove comment to use latest development version
import sys; sys.path.insert(0, '../')

# import libraries
import raccoon as rc

BList¶

The underlying data structure can be any drop-in replacement for list, in this example blist is used.

from blist import blist

# Construct with blist
df_blist = rc.DataFrame({'a': [1, 2, 3]}, index=[5, 6, 7], dropin=blist)

# see that the data structures are all blists
df_blist.data

blist([blist([1, 2, 3])])

df_blist.index

blist([5, 6, 7])

df_blist.columns

blist(['a'])

# the dropin class
df_blist.dropin

blist.blist

All the standard functionality works exactly the same

df_blist[6, 'a']

df_blist[8, 'b'] = 44
print(df_blist)

  index    a    b
-------  ---  ---
      5    1
      6    2
      7    3
      8        44

Works for Series as well

# Construct with blist=True, the default
srs_blist = rc.Series([1, 2, 3], index=[5, 6, 7], dropin=blist)

# see that the data structures are all blists
srs_blist.data

blist([1, 2, 3])

srs_blist.index

blist([5, 6, 7])
