How can I filter lines on load in Pandas read_csv function?
You can specify nrows parameter.

import pandas as pd
df = pd.read_csv('file.csv', nrows=100)

This code works well in version 0.20.3.
How can I filter which lines of a CSV to be loaded into memory using pandas?  This seems like an option that one should find in read_csv.  Am I missing something?
Example: we've a CSV with a timestamp column and we'd like to load just the lines that with a timestamp greater than a given constant.
