How to add a few empty rows into a pandas dataframe

[python_newbie09]

Hi, so far the examples I have found seems to only add 1 empty row to an existing dataframe but what if I have a specified number of empty rows that I want to add to a dataframe, how can this be done?

I tried the approach below:

for col in df.columns:
    df.reindex(df.index.values.tolist()+100)

but i am getting the error below:

TypeError: can only concatenate list (not "int") to list

You don't need to iterate over all columns, just do something like this

df.reindex(df.index.tolist() + list(range(20, 40)))

thanks, this worked!
