Subsetting columns

When working with data, you may not need all of the variables in your dataset. Square brackets ([]) can be used to select only the columns that matter to you in an order that makes sense to you. To select only "col_a" of the DataFrame df, use

df["col_a"]

To select "col_a" and "col_b" of df, use

df[["col_a", "col_b"]]

homelessness is available and pandas is loaded as pd.
