需要解决在dataframe和get datetime中处理时间戳的问题

pip install pandas

import pandas as pd

# 创建示例DataFrame
data = {
    'timestamp': [1633072800, 1633159200, 1633245600]  # Unix时间戳
}
df = pd.DataFrame(data)

# 将时间戳转换为日期时间
df['datetime'] = pd.to_datetime(df['timestamp'], unit='s')

print(df)

    timestamp            datetime
0  1633072800 2021-10-01 00:00:00
1  1633159200 2021-10-02 00:00:00
2  1633245600 2021-10-03 00:00:00

import pandas as pd

# 创建示例DataFrame
data = {
    'datetime': ['2021-10-01 00:00:00', '2021-10-02 00:00:00', '2021-10-03 00:00:00']
}
df = pd.DataFrame(data)

# 将字符串转换为日期时间
df['datetime'] = pd.to_datetime(df['datetime'])

# 将日期时间转换为时间戳
df['timestamp'] = df['datetime'].astype(int) // 10**9

print(df)

             datetime   timestamp
0 2021-10-01 00:00:00  1633072800
1 2021-10-02 00:00:00  1633159200
2 2021-10-03 00:00:00  1633245600
