在python pandas中创建交叉表，以显示存在哪些值

import pandas as pd

# 创建一个示例数据集
data = {
    'Gender': ['Female', 'Male', 'Female', 'Male', 'Male'],
    'Age': ['18-24', '25-34', '35-44', '18-24', '25-34'],
    'Nationality': ['USA', 'USA', 'Canada', 'Canada', 'USA'],
    'Education': ['Bachelor', 'Master', 'Bachelor', 'PhD', 'PhD'],
    'Count': [1, 2, 3, 4, 5]
}

df = pd.DataFrame(data)

# 创建交叉表
cross_table = pd.crosstab(df['Gender'], df['Nationality'])

print(cross_table)

Nationality  Canada  USA
Gender                   
Female            1    1
Male              1    2
