hi @sbtr1 ,
thanks for helping on this.
please find my review comments below:

I've run the tests and it works. However, please consider the following minor changes and let me know once you have them applied:
file: data_cleaning/clean_wpdx_sample_data.py

• in the clean_col_count function, please update the documentation comment to point to the correct card. It currently points to: https://trello.com/c/HHzNs0hS/1-column-countryname
  file: data_cleaning/test_clean_wpdx_sample_data.py
• in the test_clean_col_count function, please update the documentation comment to refer to "col_count". Currently, it says "country_name".
• Apart from the negative case. e.g. assert clean_wpdx_sample_data.clean_col_count('123') == 123

Feel free to let me know if there's any clarification.
Thanks again for the help.
