Pandas: Datetime and is interchangeable with it in most cases

Pandas Time Series: Exercise-2 with Solution

Write a Pandas program to create
a) a specific date using timestamp.
b) date and time using timestamp.
c) a time adds in the current local date using timestamp.
d) current date and time using timestamp.

Sample Solution:

Python Code :

import pandas as pd
#from datetime import datetime
print("\nA specific date using timestamp:")
print(pd.Timestamp('2016-11-10'))
print("\nDate and time using timestamp:")
print(pd.Timestamp('2012-05-03 11:30'))
print("\nA time adds in the current local date using timestamp:")
print(pd.Timestamp('11:30'))
print("\nCurrent date and time using timestamp:")
print(pd.Timestamp("now"))

Sample Output:

A specific date using timestamp:
2016-11-10 00:00:00

Date and time using timestamp:
2012-05-03 11:30:00

A time adds in the current local date using timestamp:
2020-08-17 11:30:00

Current date and time using timestamp:
2020-08-17 10:49:29.945939

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")
