A brief discussion on using the datetime package to perform some time operations in Python
A brief discussion on using the datetime package to perform some time operations in Python
1. Calculate the time difference between two given times
import datetime as dt # current time cur_time = dt.datetime.today() # one day pre_time = dt.date(2016, 5, 20) # eg: 2016.5.20 delta = cur_time - pre_time # if you want to get discrepancy in days print delta.days # if you want to get discrepancy in hours print delta.hours # and so on
2. Get the time n days ago
cur_time = dt.now() # previous n days pre_time = dt.timedelta(days=n)
3. Accurate the given time to days or other units
cur_time = dt.now() # get day of current time cur_day = cur_time.replace(hour=0, minute=0, second=0, mircrosecond=0)
4. Get a series of time series (return list)
cur_time = dt.datetime.today() datelist = [cur_time - dt.timedelta(days=x) for x in range(0, 100)]
or
import pandas as pd datelist = pd.date_range(pd.datetime.today(), periods=100).tolist()
5. Convert time string to datetime type
date_formate = "%Y-%m-%d" # year-month-day
time = dt.strptime('2016-06-22', date_format)6. Convert time type to string type
time_str = dt.strftime("%Y-%m-%d", dt.now()) # return like "2016-06-22"The above is the complete content of the editor’s brief discussion on using the datetime package to perform some time operations in Python. I hope you will support Script Home~
