Pandas: Business quarterly begin and end dates of a specified year

Pandas Time Series: Exercise-22 with Solution

Write a Pandas program to find the all the business quarterly begin and end dates of a specified year.

Sample Solution:

Python Code :

import pandas as pd
q_start_dates = pd.date_range('2020-01-01', '2020-12-31', freq='BQS-JUN')
q_end_dates = pd.date_range('2020-01-01', '2020-12-31', freq='BQ-JUN')
print("All the business quarterly begin dates of 2020:")
print(q_start_dates.values)
print("\nAll the business quarterly end dates of 2020:")
print(q_end_dates.values)

Sample Output:

All the business quarterly begin dates of 2020:
['2020-03-02T00:00:00.000000000' '2020-06-01T00:00:00.000000000'
 '2020-09-01T00:00:00.000000000' '2020-12-01T00:00:00.000000000']

All the business quarterly end dates of 2020:
['2020-03-31T00:00:00.000000000' '2020-06-30T00:00:00.000000000'
 '2020-09-30T00:00:00.000000000' '2020-12-31T00:00:00.000000000']

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")
