Pandas: Extract the day name from a specified date

Pandas Time Series: Exercise-25 with Solution

Write a Pandas program to extract the day name from a specified date. Add 2 days and 1 business day with the specified date.

Sample Solution:

Python Code :

import pandas as pd
newday = pd.Timestamp('2020-02-07')
print("First date:")
print(newday)
print("\nThe day name of the said date:")
print(newday.day_name())
print("\nAdd 2 days with the said date:")
newday1 = newday + pd.Timedelta('2 day')
print(newday1.day_name())
print("\nNext business day:")
nbday = newday + pd.offsets.BDay()
print(nbday.day_name())

Sample Output:

First date:
2020-02-07 00:00:00

The day name of the said date:
Friday

Add 2 days with the said date:
Sunday

Next business day:
Monday

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")
