Pandas Datetime: Convert given datetime to timestamp
Write a Pandas program to convert given datetime to timestamp.
Sample Solution :
Python Code :
import pandas as pd
import datetime as dt
import numpy as np
df = pd.DataFrame(index=pd.DatetimeIndex(start=dt.datetime(2019,1,1,0,0,1),
end=dt.datetime(2019,1,1,10,0,1), freq='H'))\
.reset_index().rename(columns={'index':'datetime'})
print("Sample datetime data:")
print(df.head(10))
df['ts'] = df.datetime.values.astype(np.int64) // 10 ** 9
print("\nConvert datetime to timestamp:")
print (df)
Sample Output:
Sample datetime data: datetime 0 2019-01-01 00:00:01 1 2019-01-01 01:00:01 2 2019-01-01 02:00:01 3 2019-01-01 03:00:01 4 2019-01-01 04:00:01 5 2019-01-01 05:00:01 6 2019-01-01 06:00:01 7 2019-01-01 07:00:01 8 2019-01-01 08:00:01 9 2019-01-01 09:00:01 Convert datetime to timestamp: datetime ts 0 2019-01-01 00:00:01 1546300801 1 2019-01-01 01:00:01 1546304401 2 2019-01-01 02:00:01 1546308001 3 2019-01-01 03:00:01 1546311601 4 2019-01-01 04:00:01 1546315201 5 2019-01-01 05:00:01 1546318801 6 2019-01-01 06:00:01 1546322401 7 2019-01-01 07:00:01 1546326001 8 2019-01-01 08:00:01 1546329601 9 2019-01-01 09:00:01 1546333201 10 2019-01-01 10:00:01 1546336801
