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")
