1. Install Python 3.7.x from https://www.python.org/downloads/ or via homebrew.

$ brew install python3   # Installed at /usr/local/Cellar/python3

Check that python3 has been installed by running it at the terminal:

$ python3
>>> Python 3.7.2

2. Download get-pip.py from https://bootstrap.pypa.io/get-pip.py and install (this should already be installed if python was installed from python.org or homebrew):

robsondepaula

import sys

salesTotal = 0
oldKey = None

for line in sys.stdin:
    data = line.strip().split("\t")
    if len(data) != 2:
        # Something has gone wrong. Skip this line.
        continue
