Dictionary In Python Presentation

Introduction to Dictionaries
Dictionaries in Python are unordered collections of key-value pairs.

They are mutable and can hold any data type, including other dictionaries.

Dictionaries are created using curly brackets {} or the dict() constructor.
 1

Accessing and Modifying Dictionary Elements
To access a value in a dictionary, use its corresponding key inside square brackets.

Values can be modified by assigning a new value to a specific key.

If a key is not found, a KeyError will be raised.
 2

Dictionary Methods and Operations
The len() function returns the number of key-value pairs in a dictionary.

The keys() method returns a list of all the keys in the dictionary.

The values() method returns a list of all the values in the dictionary.
 3

Adding and Removing Elements in Dictionaries
To add a new key-value pair, simply assign a value to a new key.

The update() method can be used to add multiple key-value pairs at once.

Use the del keyword to remove a specific key-value pair from the dictionary.
 4

Useful Dictionary Techniques and Tips
The get() method allows you to retrieve a value for a specific key, with a default value if the key is not found.

The items() method returns a list of tuples, where each tuple contains a key-value pair.

Dictionaries can be sorted using the sorted() function based on keys or values. Note: Please feel free to customize the content and design of the slides as per your requirements.
