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]:
