Pandas: Calculate one business day from a specified date
Pandas Time Series: Exercise-27 with Solution
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.
Sample Solution:
Python Code :
import pandas as pd
from pandas.tseries.offsets import *
import datetime
from datetime import datetime, date
dt = datetime(2020, 1, 4)
print("Specified date:")
print(dt)
print("\nOne business day from the said date:")
obday = dt + BusinessDay()
print(obday)
print("\nTwo business days from the said date:")
tbday = dt + 2 * BusinessDay()
print(tbday)
print("\nThree business days from the said date:")
thbday = dt + 3 * BusinessDay()
print(thbday)
print("\nNext business month end from the said date:")
nbday = dt + BMonthEnd()
print(nbday)
Sample Output:
Specified date: 2020-01-04 00:00:00 One business day from the said date: 2020-01-06 00:00:00 Two business days from the said date: 2020-01-07 00:00:00 Three business days from the said date: 2020-01-08 00:00:00 Next business month end from the said date: 2020-01-31 00:00:00

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")
