How to read the data

• Download the zipped file: ratebeer.json.gz
• Unzip it in the folder to create ratebeer.json
• Load the data in memory in the df_raw dataframe using the snippet below (example to read only the first 100000 rows):

import pandas as pd


def parse(path):
    with open(path, "r") as f:
        for line in f:
            yield eval(line)


filename = "ratebeer.json"
N_rows = 100000
df_raw = pd.DataFrame.from_records(parse(filename), nrows=N_rows)
