Example Usage for Drop-in List Replacements

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

BList

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



In [3]:

    
from blist import blist



In [4]:

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



In [5]:

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









    Out[5]:





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



In [6]:

    
df_blist.index









    Out[6]:





blist([5, 6, 7])



In [7]:

    
df_blist.columns









    Out[7]:





blist(['a'])



In [8]:

    
# the dropin class
df_blist.dropin









    Out[8]:





blist.blist

All the standard functionality works exactly the same



In [9]:

    
df_blist[6, 'a']









    Out[9]:





2



In [10]:

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









    



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

Works for Series as well



In [11]:

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



In [12]:

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









    Out[12]:





blist([1, 2, 3])



In [13]:

    
srs_blist.index









    Out[13]:





blist([5, 6, 7])
