Pandas: Date from a given year, month, day and date from a given string formats

Pandas Time Series: Exercise-3 with Solution

Write a Pandas program to create a date from a given year, month, day and another date from a given string formats.

Sample Solution:

Python Code :

from datetime import datetime
date1 = datetime(year=2020, month=12, day=25)
print("Date from a given year, month, day:")
print(date1)
from dateutil import parser
date2 = parser.parse("1st of January, 2021")
print("\nDate from a given string formats:")
print(date2)

Sample Output:

Date from a given year, month, day:
2020-12-25 00:00:00

Date from a given string formats:
2021-01-01 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")
