Here's Python Dictionary that explained how to lookup it using Key. Dictionary in Python is Key/Value pair. It's different from the list. The basic rule to identify; is enclosed in flower brackets ({}). Here's a demo about lookup and how to test it.
Dictionary = { 'key' : 'value', 'key: value' }

Dictionary
Example
my_dict = {'name' : 'srini' , 'salary' : '100000', 'skills' : 'python' }
Here, 'name' is the label.
Then, :
Then, 'srini' -> Value
Explanation
- Data is enclosed in flower brackets
- It's an unordered list
- You can manipulate data (mutable)
- You can access the value of a particular key. So, in Python, it's called a Lookup. It's one of the best interview questions.

Lookup Dictionary by Key
Python Lookup (a.k.a Dictionary). You can access data quickly. It's really super-speed.
my_dict['name']
The result will be: 'srini'
- You should use square brackets ([]) to get lookup data
- Use key-value in square brackets ([]) with a single quote, you will get value
Output from Lookup
I am now adding new value to the Lookup.
>>> my_dict['role'] = 'Manager'
Now, the my_dict will'be :
>>> my_dict = {'name' : 'srini' , 'salary' : '100000', 'skills' : 'python' , 'role' : 'Manager'}
- The order of assignmenet will not match with actula storing in Python
- The order of Key/Value storage is taken care by interpreter
