Python:如何计算variable=yes的平均时间

# 假设时间和变量值存储在一个名为data的字典中，格式为{"time": "2022-01-01 10:30:00", "variable": "yes"}

data = [
    {"time": "2022-01-01 10:30:00", "variable": "yes"},
    {"time": "2022-01-01 11:30:00", "variable": "no"},
    {"time": "2022-01-01 12:30:00", "variable": "yes"},
    {"time": "2022-01-01 13:30:00", "variable": "yes"}
]

time_list = []  # 存储满足条件的时间值

for item in data:
    if item["variable"] == "yes":
        time_list.append(item["time"])

if len(time_list) > 0:
    total_time = sum(time_list)
    average_time = total_time / len(time_list)
    print(f"满足条件的平均时间为：{average_time}")
else:
    print("未找到满足条件的时间值")
