Pandas Time Series: Exercise-16 with Solution

Write a Pandas program to create a time series combining hour and minute.

Sample Solution:

Python Code :

import pandas as pd
result = pd.timedelta_range(0, periods=30, freq="1H20T")
print("For a frequency of 1 hours 20 minutes, here we have combined the hour (H) and minute (T):\n")
print(result)

Sample Output:

For a frequency of 1 hours 20 minutes, here we have combined the hour (H) and minute (T):

TimedeltaIndex(['0 days 00:00:00', '0 days 01:20:00', '0 days 02:40:00',
                '0 days 04:00:00', '0 days 05:20:00', '0 days 06:40:00',
                '0 days 08:00:00', '0 days 09:20:00', '0 days 10:40:00',
                '0 days 12:00:00', '0 days 13:20:00', '0 days 14:40:00',
                '0 days 16:00:00', '0 days 17:20:00', '0 days 18:40:00',
                '0 days 20:00:00', '0 days 21:20:00', '0 days 22:40:00',
                '1 days 00:00:00', '1 days 01:20:00', '1 days 02:40:00',
                '1 days 04:00:00', '1 days 05:20:00', '1 days 06:40:00',
                '1 days 08:00:00', '1 days 09:20:00', '1 days 10:40:00',
                '1 days 12:00:00', '1 days 13:20:00', '1 days 14:40:00'],
               dtype='timedelta64[ns]', freq='80T')

Previous: Write a Pandas program to get a time series with the last working days of each month of a specific year.
Next: Write a Pandas program to convert unix/epoch time to a regular time stamp in UTC. Also convert the said timestamp in to a given time zone.

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")
