计算Pandas中的百分比差异并对结果应用特殊条件

import pandas as pd

# 创建一个示例数据集
data = {'A': [10, 20, 30, 40, 50]}
df = pd.DataFrame(data)

# 计算百分比差异
df['Percentage Change'] = df['A'].pct_change() * 100

# 应用特殊条件
df['Result'] = df['Percentage Change'].apply(lambda x: 'Condition Met' if x > 10 else 'Condition Not Met')

# 打印结果
print(df)

    A  Percentage Change           Result
0  10                NaN  Condition Not Met
1  20         100.000000    Condition Met
2  30          50.000000    Condition Met
3  40          33.333333    Condition Met
4  50          25.000000    Condition Met
