如何从Python字典创建自定义CSV文件？

import csv

data = [
    {'Name': 'John', 'Age': 25, 'City': 'New York'},
    {'Name': 'Emma', 'Age': 30, 'City': 'London'},
    {'Name': 'Mike', 'Age': 35, 'City': 'Paris'}
]

fields = ['Name', 'Age', 'City']

filename = 'custom.csv'
delimiter = ','

with open(filename, 'w', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=fields, delimiter=delimiter)

    writer.writeheader()

    for row in data:
        writer.writerow(row)

import csv

data = [
    {'Name': 'John', 'Age': 25, 'City': 'New York'},
    {'Name': 'Emma', 'Age': 30, 'City': 'London'},
    {'Name': 'Mike', 'Age': 35, 'City': 'Paris'}
]

fields = ['Name', 'Age', 'City']
filename = 'custom.csv'
delimiter = ','

with open(filename, 'w', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=fields, delimiter=delimiter)
    writer.writeheader()
    for row in data:
        writer.writerow(row)
