Selecting columns

Unlike R, Python doesn't have a built-in data structure similar to data frames. The library pandas gives you access to DataFrames in Python.

In pandas, you can either use the dot (.) notation or the square bracket notation ([ ]) to select columns. However, if your column name has a space in it, or if the name clashes with a DataFrame attribute, then the convenient dot notation won't work.
