How to create empty python framework where df.empty results in True

The simplest is pd.DataFrame()

:

df = pd.DataFrame()   

df.empty
# True

      

        
        
        
      

    

If you want to create a dataframe to specify the number of columns:

df = pd.DataFrame(columns=['A', 'B'])

df.empty
# True

      

        
        
        
      

    

Also, an array of shape (1, 1) is not empty (it has one line), which is why you get empty = False, to create an empty array it must have shape (0, n):

df = pd.DataFrame(pd.np.empty((0, 3)))

df.empty
# True
