In Python 2 when both x1 and x2 are of an integer type divide will behave like floor_divide. Of course this requires NumPy. This is because xreplaceGuru99Python returns a copy of X with replacements made.

DfDataFrame Column dfDataFrame Columnreplacenpnan 0 For the whole DataFrame using pandas. Use NULLIF function in the denominator with second argument value zero If the value of the first argument is also zero this function returns a null value.
