這將為您的數據框添加增量日期。

import pandas as pd

import datetime as dt

ddict = {

    'Date': ['2014-12-29','2014-12-30','2014-12-31','','','','',]

    }

data = pd.DataFrame(ddict)

data['Date'] = pd.to_datetime(data['Date'])

def fill_dates(data_frame, date_col='Date'):

    ### Seconds in a day (3600 seconds per hour x 24 hours per day)

    day_s = 3600 * 24

    ### Create datetime variable for adding 1 day

    _day = dt.timedelta(seconds=day_s)

    ### Get the max non-null date

    max_dt = data_frame[date_col].max()

    ### Get index of missing date values

    NaT_index = data_frame[data_frame[date_col].isnull()].index

    ### Loop through index; Set incremental date value; Increment variable by 1 day

    for i in NaT_index:

        data_frame[date_col][i] = max_dt + _day

        _day += dt.timedelta(seconds=day_s)

### Execute function

fill_dates(data, 'Date')
