Join Michele Vallisneri for an in-depth discussion in this video Pandas overview, part of Python: Data Analysis.
- Although Pandas is still a young package,…only at version .17 compared to 1.9 for NumPy,…it has gained broad acceptance in the Python community…as the data analysis tool for Python.…Pandas is built on top of NumPy…and it could be loosely described as NumPy with labels.…That is, it is a package that deals with data…in tabular form but which attaches more general…labels and not just numerical indices…to the rows and columns.…Here, when we say, "tables," we include also…one dimensional vectors, three dimensional…data cubes, and so on.…
Pandas significantly enhances NumPy.…In addition to adding data labels and descriptive indices,…it is also more robust in handling common data formats…and missing data.…It also adds relational-database operations,…such as joins.…If you want to do data science with Python,…I really recommend that you learn Pandas.…

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').
