Indexing in python dataframe using iloc to select all columns except the first column

I am trying to select all columns in a pandas dataframe in python except the first column using iloc.

I am able to select all column except the last one using the code

Pre_Processed.iloc[:,0:-1]

Could anyone please help me with this?

Solution

  • Try this

    Pre_Processed.iloc[:,1:]

    Index with iterable works like

    iterable[start:end:stride]
