python - Reserializing row index after row selection in pandas data frame -

i have following data frame:

import pandas pd df = pd.dataframe({ 'gene':["foo","bar","qux","woz"], 'cell1':[5,0,1,0], 'cell2':[12,90,13,0]}) df = df[["gene","cell1","cell2"]]

that looks this:

  gene  cell1  cell2 0  foo      5     12 1  bar      0     90 2  qux      1     13 3  woz      0      0

after performing row selection this:

in [168]: ndf = df[(df[['cell1','cell2']] == 0 ).any(axis=1)]  in [169]: ndf out[169]:   gene  cell1  cell2 1  bar      0     90 3  woz      0      0

note ndf has row index 1 , 3 how can re index 0 , 1.

the expcted output is:

   gene  cell1  cell2 0  bar      0     90 1  woz      0      0

i tried failed:

ndf.reset_index

what's right way it?

try 1

ndf.reset_index(drop = true)
