将具有多个键的Python字典编写为CSV

import csv

data = [
    {'Name': 'John', 'Age': 25, 'Country': 'USA'},
    {'Name': 'Emily', 'Age': 30, 'Country': 'Canada'},
    {'Name': 'Tom', 'Age': 28, 'Country': 'UK'}
]

filename = 'data.csv'

with open(filename, 'w', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=data[0].keys())
    writer.writeheader()
    writer.writerows(data)

import csv

data = [
    {'Name': 'John', 'Age': 25, 'Country': 'USA'},
    {'Name': 'Emily', 'Age': 30, 'Country': 'Canada'},
    {'Name': 'Tom', 'Age': 28, 'Country': 'UK'}
]

filename = 'data.csv'

with open(filename, 'w', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=data[0].keys())
    writer.writeheader()
    writer.writerows(data)
