[Python] Read and Parse Files in Python

This lesson will teach you how to read the contents of an external file from Python. You will also learn how to use the python csv module to read and parse csv data, as well as the json module to read and parse json data.

# f = open('animals.csv')

# for line in f:
#     print(line)

# f.close()

# with open('animals.csv', 'r') as f:
#     print(f.read())

# import csv
# with open('animals.csv', 'r') as f:
#     animals = csv.reader(f)
#     for row in animals:
#         if row[-1] == 'True':
#             print("{0} is a {1} and is housebroken".format(row[0], row[1]))
#         elif row[-1] == 'False':
#             print("{0} is a {1} and is not housebroken!".format(row[0], row[1]))

# import json
# with open('animals.json', 'r') as r:
#     data = json.load(r)
#     for row in data:
#         print(row['name'])

# f = open('cars.txt', 'a')
# cars = ['chevy', 'tesla', 'ford']
# for car in cars:
#     f.write(car + '\n')

# f.close()

# with open('cars.txt', 'a') as f:
#     cars = ['chevy', 'vw', 'mazda']
#     for car in cars:
#         f.write(car + '\n')

cars = [
    {"make": "chevy"},
    {"make": "tesla"},
    {"make": "porsche"}
]
import json
with open('cars.json', 'w') as f:
    json.dump(cars, f)
