Pandas: Check if a day is a business day (weekday) or not

Pandas Time Series: Exercise-14 with Solution

Write a Pandas program to check if a day is a business day (weekday) or not.

Sample Solution:

Python Code :

import pandas as pd
def is_business_day(date):
    return bool(len(pd.bdate_range(date, date)))
print("Check busines day or not?")
print('2020-12-01: ',is_business_day('2020-12-01'))
print('2020-12-06: ',is_business_day('2020-12-06'))
print('2020-12-07: ',is_business_day('2020-12-07'))
print('2020-12-08: ',is_business_day('2020-12-08'))

Sample Output:

Check busines day or not?
2020-12-01:  True
2020-12-06:  False
2020-12-07:  True
2020-12-08:  True

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")
