Hi Bappa,
Glad to see doubts being posted on the Bangpypers mailing list as advised
by Anand.
Please use some pasting tool like https://pastebin.com/ for future queries
and provide the links so people can view your code more easily.

As for this particular issue, Python interprets "df" like a function
because you're using it like a function by passing 'height' as a parameter.
If you want to assign the modified value of 'Height (inches)' to a new
column, you have to create it as
df['height'] = ...

Modified your code here - https://pastebin.com/H8uMGKEC

Hope this helps.
