I was wondering, How would I go about filtering out people who own over 20 games, and they don't have a Mac OS System. I need it to be done via a python script, and when run, it outputs its data in a seperate file, like a text file or something. Thanks!
I'd suggest using the Pandas library.
Code is basically as follows:
import pandas as pd
data = pd.read_csv('put in your csv filename here')
# Filter the data accordingly.
data = data[data['Games Owned'] > 20]
data = data[data['OS'] == 'Mac']
data.to_csv('output.csv')Here's a solution in pure python that writes the filtered output to a textfile (csv) as requested.
import csv
with open('games.csv', 'rb') as csvfile:
# handle header line, save it for writing to output file
header = next(csvfile).strip("\n").split(",")
reader = csv.reader(csvfile)
results = filter(lambda row: row[1] != 'Mac' and int(row[2]) > 20, reader)
with open('output.csv', 'wb') as outfile:
writer = csv.writer(outfile)
writer.writerow(header)
for result in results:
writer.writerow(result)
