3、气象局使用元组（tuple）记录了某市过去一周的最高温度和最低温度：最高温度：30, 28, 29, 31, 33, 35, 32最低温度：20, 21, 19, 22, 23, 24, 20请列出过去一周的最高温度、最低温度和平均温度。python

代码如下：

high_temperatures = (30, 28, 29, 31, 33, 35, 32)
low_temperatures = (20, 21, 19, 22, 23, 24, 20)

# 计算最高温度、最低温度和平均温度，并输出结果
max_temperature = max(high_temperatures)
min_temperature = min(low_temperatures)
avg_temperature = (sum(high_temperatures) + sum(low_temperatures)) / 14

print("过去一周的最高温度是：", max_temperature)
print("过去一周的最低温度是：", min_temperature)
print("过去一周的平均温度是：", avg_temperature)
