pandas[2] is _awesome_. 
Someone recently blasted through much of "Python for Data Analysis"[1].
pandas teaser:

    import pandas.io.data as web
    google = web.get_data_yahoo("GOOG")
    google["Close"].describe()
    close = google.Close
    close["2009-11"]
    google.pct_change().abs().sort_index(by="Close", ascending=False)[:10]
    close - close.mean()
    close.skew()
    close.quantile(0.95)
    # close.pct_change().sort()

ipython is nifty also
