Pass column index and range simultaneously in Pandas iloc

Question

Suppose I have a dataframe with 100 columns. I want to select only 0,1 and 51-100 columns for all rows. I am trying something like this as of now:

df.iloc[:,         


        

Answer 1

You can do this without numpy.r_:

new_df = df.iloc[:, [0, 1] + list(range(51,101))]
