Python程序---随机生成数，并求其平均值

# 随机生成4个学生一周的体温，并求其平均温度

import random
t=[]   #创建空列表

for i in range(7):
    t.append(round(random.uniform(36, 38),2))#
print(t)

avg=sum(t)/len(t)
print(avg)

C = [[] for i in range(4)]      #先列后行（4行不知道多少列）

for i in range(4):
    for j in range(7):
        t = round(random.uniform(36, 38),2)
        C[i].append(t)
        
print(C)

# 计算每位同学一周的平均体温
avg_t = []
t = 0
for row in C:
    t=0
    for col in row:
        t = t + col
    avg_t.append(round(t / 7,2))

print(avg_t)

输出：
