根据other列中的出现情况在pandas中创建新的时间戳

import pandas as pd

# 创建示例数据
data = {'other': ['2022-01-01', '2022-01-02', '2022-01-03', 'N/A', '2022-01-05']}
df = pd.DataFrame(data)

# 将字符串转换为时间戳
df['timestamp'] = pd.to_datetime(df['other'], errors='coerce')

# 输出结果
print(df)

        other  timestamp
0  2022-01-01 2022-01-01
1  2022-01-02 2022-01-02
2  2022-01-03 2022-01-03
3         N/A        NaT
4  2022-01-05 2022-01-05
