我需要帮助计算Pandas数据帧标题下的字符串和时间线

import pandas as pd

# 创建一个示例DataFrame
data = {'Name': ['Alice', 'Bob', 'Charlie'],
        'Age': [25, 30, 35],
        'Timestamp': ['2022-01-01', '2022-02-01', '2022-03-01']}
df = pd.DataFrame(data)

# 计算字符串长度
df['Name_Length'] = df['Name'].apply(len)

# 将Timestamp列转换为时间类型
df['Timestamp'] = pd.to_datetime(df['Timestamp'])

# 计算时间线
df['Timeline'] = df['Timestamp'].apply(lambda x: x.year)

# 打印结果
print(df)

      Name  Age  Timestamp  Name_Length  Timeline
0    Alice   25 2022-01-01            5      2022
1      Bob   30 2022-02-01            3      2022
2  Charlie   35 2022-03-01            7      2022
