df_dry.dropna(subset=['Quantity', 'Rate'])

I was trying to drop the row if any value from Quantity or Rate was missing, but I’m getting

TypeError Traceback (most recent call last)
Cell In[36], line 1
—-> 1 df_dry.dropna(subset=[‘Quantity’, ‘Rate’], axis = 0)

TypeError: ‘bool’ object is not callable

I tried using

def isFillled(cls,row,col,myMap):
        cls.isFilled = True

But it didn’t work
