使用python将字典中的键和值写入csv

import csv

my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}

csv_file = 'data.csv'

with open(csv_file, 'w', newline='') as file:
    writer = csv.writer(file)

writer.writerow(['Key'])

for key, value in my_dict.items():
    writer.writerow([key])
    writer.writerow([value])

file.close()

import csv

my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
csv_file = 'data.csv'

with open(csv_file, 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerow(['Key'])
    for key, value in my_dict.items():
        writer.writerow([key])
        writer.writerow([value])

file.close()
