CSV:如何在列表中找到下一个更大的值(python)？

import csv

def find_next_greater_value(lst, target):
    greater_value = None
    for value in lst:
        if value > target:
            greater_value = value
            break
    return greater_value

# 读取CSV文件
with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    data = list(reader)

# 将CSV数据转换为列表
values = [int(row[0]) for row in data]

# 调用函数查找下一个更大的值
target_value = 10
next_greater_value = find_next_greater_value(values, target_value)

if next_greater_value is not None:
    print(f"The next greater value after {target_value} is {next_greater_value}.")
else:
    print(f"There is no greater value after {target_value} in the list.")
