1. JMESPath

We work with JSON data a lot in the real world. Would it not be nice to be able to extract and query for values in our JSON data? JMESPath (james path) enables the extraction of elements from a JSON document. To use JMESPath, you will have to install the jmespath module.

 1import jmespath
 3planets = {
 4    'planets': [
 5        {'name': 'mercury', 'is_solid': True},
 6        {'name': 'venus', 'is_solid': True},
 7        {'name': 'earth', 'is_solid': True},
 8        {'name': 'mars', 'is_solid': True},
 9        {'name': 'jupiter', 'is_solid': False},
10        {'name': 'saturn', 'is_solid': False},
11        {'name': 'uranus', 'is_solid': False},
12        {'name': 'neptune', 'is_solid': False},
13    ]
16print(jmespath.search('planets[*].name', planets))
17print(jmespath.search('planets[*].is_solid', planets))

2. python-dateutil

Date and time information is everywhere. It is not easy to parse, clean and format date and time information. The python-dateutil package can help ease the pain of dealing with date and time data.

1from dateutil.parser import parse
3logline = 'INFO 2021-12-31T23:59:11 Almost new year!'
4timestamp = parse(logline, fuzzy=True)

3. termtables

If you have tabular data, you will find yourself wanting to pretty print the content from time to time if the data is not so big. There are many libraries to help you do so.

 1import termtables as tt
 3header = ['first_name', 'last_name', 'age', 'height', 'is_cool']
 4data = [
 5    ['john', 'doe', 23, 5.5, True],
 6    ['jack', 'johnson', 34, 6.2, False]
10    data,
11    header=header,
12    style=tt.styles.markdown,
13    padding=(0, 1),
14    alignment="lcrlc"
