Pandas: Date range using a startpoint date and a number of periods
Pandas Time Series: Exercise-8 with Solution
Write a Pandas program to create a date range using a startpoint date and a number of periods.
Sample Solution:
Python Code :
import pandas as pd
date_range = pd.date_range('2020-01-01', periods=45)
print("Date range of perods 45:")
print(date_range)
Sample Output:
Date range of perods 45: DatetimeIndex(['2020-01-01', '2020-01-02', '2020-01-03', '2020-01-04', '2020-01-05', '2020-01-06', '2020-01-07', '2020-01-08', '2020-01-09', '2020-01-10', '2020-01-11', '2020-01-12', '2020-01-13', '2020-01-14', '2020-01-15', '2020-01-16', '2020-01-17', '2020-01-18', '2020-01-19', '2020-01-20', '2020-01-21', '2020-01-22', '2020-01-23', '2020-01-24', '2020-01-25', '2020-01-26', '2020-01-27', '2020-01-28', '2020-01-29', '2020-01-30', '2020-01-31', '2020-02-01', '2020-02-02', '2020-02-03', '2020-02-04', '2020-02-05', '2020-02-06', '2020-02-07', '2020-02-08', '2020-02-09', '2020-02-10', '2020-02-11', '2020-02-12', '2020-02-13', '2020-02-14'], dtype='datetime64[ns]', freq='D')

Previous: Write a Pandas program to create a time series object that has time indexed data. Also select the dates of same year and select the dates between certain dates.
Next: Write a Pandas program to create a whole month of dates in daily frequencies. Also find the maximum, minimum timestamp and indexs.

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")
