如何对数值列在特定范围内的组进行分组和计数？

# 数值列
data = [5, 12, 18, 25, 8, 15, 22, 30, 3, 9]

# 定义范围和对应的组名
ranges = [(0, 10), (10, 20), (20, 30)]
groups = ['0-10', '10-20', '20-30']

# 初始化每个组的计数为0
count = {group: 0 for group in groups}

# 遍历数值列
for value in data:
    # 检查数值所属的范围
    for i, (start, end) in enumerate(ranges):
        if start <= value < end:
            # 将计数加入相应的组
            count[groups[i]] += 1
            break

# 输出每个组的计数结果
for group, value in count.items():
    print(f'{group}: {value}')
