== CSV ==

To import a CSV file:

{{{
import pandas as pd
data = pd.read_csv("example.csv", index_col="UniqueID")
}}}

If the '''`index_col`''' argument is left off, the `DataFrame` will be indexed by sequential integers.

Columns can be filtered with the '''`usecols`''' argument.

{{{
data = pd.read_csv("example.csv", usecols=["First"])
}}}
