如何在python中编写csv中的文件名和行数？

import csv

with open('filename.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile)
    writer.writerow(['Name', 'Age', 'City'])
    writer.writerow(['John', '25', 'New York'])
    writer.writerow(['Alice', '30', 'London'])

with open('filename.csv', 'r') as csvfile:
    reader = csv.reader(csvfile)
    csv_data = list(reader)
    num_rows = len(csv_data)
    file_name = csvfile.name

import csv

# 创建CSV文件并写入数据
with open('filename.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile)
    writer.writerow(['Name', 'Age', 'City'])
    writer.writerow(['John', '25', 'New York'])
    writer.writerow(['Alice', '30', 'London'])

# 获取CSV文件名和行数
with open('filename.csv', 'r') as csvfile:
    reader = csv.reader(csvfile)
    csv_data = list(reader)
    num_rows = len(csv_data)
    file_name = csvfile.name

print("CSV文件名：", file_name)
print("行数：", num_rows)
