How to replace both the diagonals of dataframe with 0 in pandas 
import pandas as pd 
import numpy as np

df = pd.DataFrame(np.random.randint(1,100, 100).reshape(10, -1))

out = df.where(df.values != np.diag(df),0,df.where(df.values != np.flipud(df).diagonal(0),0,inplace=True))
pandas change diagonal 
In [21]: df.values[[np.arange(df.shape[0])]*2] = 0

In [22]: df
Out[22]: 
          0         1         2         3         4
