python -查找时间序列中的第一个匹配项

import datetime

def find_first_match(time_series, target):
    for timestamp in time_series:
        if timestamp == target:
            return timestamp
    return None

# 示例时间序列
time_series = [
    datetime.datetime(2022, 1, 1),

    datetime.datetime(2022, 1, 3),
    datetime.datetime(2022, 1, 4),
    datetime.datetime(2022, 1, 5)

# 目标时间
target_time = datetime.datetime(2022, 1, 3)

# 查找第一个匹配项
result = find_first_match(time_series, target_time)

if result:
    print("第一个匹配项是:", result)
else:
    print("未找到匹配项")
