How can I modify this code to add a punctuation mark at the end of the sentence without a space?

This code:

lst = range(59, 125)

    df2 = df2.rename(columns={col: col+'.'
                        for idx, col in enumerate(df2.columns)
                        if idx in lst})

adds a punctuation mark at the end of every title in a column. But it adds a spacemark just before the punctuation mark. E.g. Code turns:

I would never do that

to:

I would never do that .

And I want:

I would never do that.

ALSO

Some titles have a question mark at the end and this code adds a punctuation mark after it. How can I modify or add to my code to not place a punctuation marks after question marks?

E.g. Code turns:

Are you satisfied?

to:

Are you satisfied?.

Try adding rstrip() function to your column. This removes right trialing withe spaces.

For not adding the point after interrogation, you should add an if exception to your code:

 lst = range(59, 125)

    df2 = df2.rename(columns={col: col.rstrip() +'.'
                        for idx, col in enumerate(df2.columns)
                        if idx in lst and col.rstrip()[-1] != '?'})

Probably because you already have a space in each column's name. Try this to strip it by using

df2 = df2.rename(columns={col: col.strip()+'.'
                        for idx, col in enumerate(df2.columns)
                        if idx in lst})
