Examples
<ASSISTANT_TASK:>
Python Code:
# @title Install dependencies
# @markdown Only execute if not already installed and running a cloud runtime
!pip install -q timesketch_api_client
# @title Import libraries
# @markdown This cell will import all the libraries needed for the running of this colab.
import altair as alt # For graphing.
import numpy as np   # Never know when this will come in handy.
import pandas as pd  # We will be using pandas quite heavily.
from timesketch_api_client import config
# @title Sketch Configuration
# @markdown Set the sketch ID for the rest of the notebook
Sketch_id = 1 #@param {type:"integer"}
# @title Timesketch connnection
ts_client = config.get_client()
sketch = ts.get_sketch(Sketch_id)

#message: A string that will be used as the message string.  
message = "" #@param {type:"string"}
#date: A string with the timestamp of the message. 
# This should be in a human readable format, eg: "2020-09-03T22:52:21". 
# if empty it will set to now
date = "2020-08-06T12:48:06.994188Z" #@param {type:"string"}
#timestamp_desc : Description of the timestamp.  
timestamp_desc = "Test_description" #@param {type:"string"}
Explanation: Fill in your event data
Put in your message, date and timestamp description

#attributes: A dict of extra attributes to add to the event.  
attributes = {"a": "alpha", "o": "omega", "g": "gamma"}
#tags: A list of strings to include as tags.
tags = ["not", "important"] 
sketch.add_event(message, date, timestamp_desc, attributes, tags)
Explanation: Attributes / Tags (optional)
Fill in additional attributes and tags
If you do not need that, empty them.
Examples:
attributes: A dict of extra attributes to add to the event.
attributes = {"a": "alpha", "o": "omega", "g": "gamma"}
