如何模拟50个随机样本并计算每个样本的均值和方差

import random
import statistics

# 模拟50个随机样本
samples = [random.randint(1, 100) for _ in range(50)]

# 计算每个样本的均值和方差
means = [statistics.mean(samples[:i+1]) for i in range(50)]
variances = [statistics.variance(samples[:i+1]) for i in range(50)]

# 打印结果
for i in range(50):
    print(f"样本{i+1}的均值为：{means[i]}，方差为：{variances[i]}")
