    #pythontip by @RashmikaNawa: How to increase speed when iterating over rows in a DataFrame? Use `itertuples()` instead of `iterrows()`. Also, consider vectorization or `apply()` instead. More info: #pandas #performance
    Rashmika Nawaratne @RashmikaNawa
    Efficient way to iterate through a #python #pandas dataframe: Usual way: for _, row in df.iterrows(): print(row['col_name']) Efficient way: (x200 speedup with .5 mil records) for row in df.itertuples(index=False): print(row[col_location]) @python_tip #performance

    #pythontip by @raymondh: A specialized tool often beats a general purpose tool * math.sqrt(x) is more accurate than x ** 0.5 * math.log2(x) is more accurate than math.log(x, 2) * math.log1p(x) is more accurate than math.log(1+x) ... For example (see the figure)

    #pythontip by @bascodes: To avoid unintended consequences, change your function defaults arguments from (first figure) to (second figure). Otherwise, calling the function without that optional argument will access the same list each time.
