Pandas Time Series: Exercise-28 with Solution

Write a Pandas program to create a period index represent all monthly boundaries of a given year. Also print start and end time for each period object in the said index.

Sample Solution:

Python Code :

import pandas as pd
import datetime
from datetime import datetime, date
sdt = datetime(2020, 1, 1)
edt = datetime(2020, 12, 31)
dateset = pd.period_range(sdt, edt, freq='M')
print("All monthly boundaries of a given year:")
print(dateset) 
print("\nStart and end time for each period object in the said index:")
for d in dateset: 
    print ("{0} {1}".format(d.start_time, d.end_time))

Sample Output:

All monthly boundaries of a given year:
PeriodIndex(['2020-01', '2020-02', '2020-03', '2020-04', '2020-05', '2020-06',
             '2020-07', '2020-08', '2020-09', '2020-10', '2020-11', '2020-12'],
            dtype='period[M]', freq='M')

Start and end time for each period object in the said index:
2020-01-01 00:00:00 2020-01-31 23:59:59.999999999
2020-02-01 00:00:00 2020-02-29 23:59:59.999999999
2020-03-01 00:00:00 2020-03-31 23:59:59.999999999
2020-04-01 00:00:00 2020-04-30 23:59:59.999999999
2020-05-01 00:00:00 2020-05-31 23:59:59.999999999
2020-06-01 00:00:00 2020-06-30 23:59:59.999999999
2020-07-01 00:00:00 2020-07-31 23:59:59.999999999
2020-08-01 00:00:00 2020-08-31 23:59:59.999999999
2020-09-01 00:00:00 2020-09-30 23:59:59.999999999
2020-10-01 00:00:00 2020-10-31 23:59:59.999999999
2020-11-01 00:00:00 2020-11-30 23:59:59.999999999
2020-12-01 00:00:00 2020-12-31 23:59:59.999999999

Previous: Write a Pandas program to calculate one, two, three business day(s) from a specified date. Also find the next business month end from a specific date.
Next: Write a Pandas program create a series with a PeriodIndex which represents all the calendar month periods in 2029 and 2031. Also print the values for all periods in 2030.

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

The os and os.path modules.

The __file__ constant

os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")

os.path.dirname(path) (returns "the directory name of pathname path")

os.getcwd() (returns "a string representing the current working directory")

os.chdir(path) ("change the current working directory to path")
