py对csv文件的增删改查

如果涉及技术方面的问题，我可以回答。对于增删改查csv文件的操作，可以使用Python的csv模块。具体操作可以参考以下代码：

1. 导入csv模块

import csv

2. 读取csv文件

with open('file.csv', newline='') as csvfile:
reader = csv.reader(csvfile)
for row in reader:
print(', '.join(row))

3. 写入csv文件

with open('file.csv', 'w', newline='') as csvfile:
writer = csv.writer(csvfile)
writer.writerow(['Column1', 'Column2', 'Column3'])
writer.writerow(['Value1', 'Value2', 'Value3'])

4. 修改csv文件

with open('file.csv', 'r', newline='') as csvfile:
reader = csv.reader(csvfile)
rows = list(reader)
rows[1][1] = 'NewValue'

with open('file.csv', 'w', newline='') as csvfile:
writer = csv.writer(csvfile)
writer.writerows(rows)

5. 删除csv文件中某一行数据

with open('file.csv', 'r') as csvfile:
reader = csv.reader(csvfile)
rows = [row for row in reader if row[0] != 'Value1']

with open('file.csv', 'w', newline='') as csvfile:
writer = csv.writer(csvfile)
writer.writerows(rows)

希望这些代码可以帮助到你。若有不明白的地方，还请与我继续交流。
