python - pandas: unable to remove the second column

Question

I am attempting to remove some columns from a DataFrame. I can successfully remove the first column but when I attempt to remove the second, it failed and I am not sure why.

Code:

I have also attempted with the same outcome:

df.drop(["StockName", "DirectorName"], 1)

Error Message:

Answer 1

@jezrael was correct with the df.columns = df.columns.str.strip(). This worked successfully. I will check to see if there are any excess spaces in the orignal file the DataFrame was created from.

TY all
