You need to pass the labels to be dropped   df drop df index  inplace True    By default  it operates on axis 0   You can achieve the same with   df iloc 0 0    which is much more efficient

If your goal is to drop the dataframe  then you need to pass all columns  For me  the best way is to pass a list comprehension to the columns kwarg  This will then work regardless of the different columns in a df  import pandas as pd  web stats     Day    1  2  3  4  2  6                 Visitors    43  43  34  23  43  23                 Bounce Rate    3  2  4  3  5  5   df   pd DataFrame web stats   df drop columns  i for i in check df columns

Overwrite the dataframe with something like that  import pandas as pd  df   pd DataFrame None    or if you want to keep columns in place  df   pd DataFrame columns df columns
