如何找到具有年龄和计数列的人口数据帧的中位数？

import pandas as pd

# 加载数据
data = pd.read_csv('population_data.csv')

# 数据清洗
data = data.dropna()  # 删除缺失值
data = data[data['age'].astype(str).str.isdigit()]  # 确保年龄列为数字类型

# 提取年龄和计数列
age_column = data['age'].astype(int)
count_column = data['count'].astype(int)

# 计算中位数
median_age = age_column.median()
median_count = count_column.median()

# 结果展示
print("年龄列的中位数：", median_age)
print("计数列的中位数：", median_count)
