Join Michele Vallisneri for an in-depth discussion in this video Challenge, part of Introduction to Data Analysis with Python.
- For your challenge, I'd like you to do the following,…for every name, compute the total number of times…that the name was used for boys,…and the total number of times that it was used for girls.…Then, identify unisex names where the ratio between…the boys total and the girls total is less than four…either way.…Last, plot the popularity of the top 10 unisex names.…This challenge should take you about 10 minutes.…

Q: The course shows how to download files from FTP and web servers using Python 3.X. How do I do the same thing with Python 2.7?
A: First import urllib, then use urllib.urlretrieve(URL,filename). For instance, to download the stations.txt files used in the chapter 5 video “Downloading and parsing data files,” you’d do urllib.urlretrieve(‘ftp://ftp.ncdc.noaa.gov/pub/data/ghcn/daily/ghcnd-stations.txt','stations.txt').
