Data types

• In C#, a boolean takes 1 bit of memory, however, if one uses sizeof(bool), it will return 1 byte, and not 1 bit. This is because the smallest addressable unit of memory is a byte. The remaining 7 bits are stuffed.
• iterrows() can be used for a pandas data frame, to get the index and the row. However, it is not the most efficient way to iterate over a data frame. The most efficient way is to use itertuples() or iteritems().
• a = {"name":10, "age":10} can be updated using a.update({"name":20}), no need to use a["name"] = 20.
