What is a flowchart and what is its primary purpose?

A flowchart is a visual tool that uses shapes and arrows to show a program's steps and logic. Its main purpose is to simplify complex code by clearly illustrating the program's flow, sequence, and relationships between processes without focusing on syntax.

What does the Terminator shape represent in a flowchart?

It represents the start or end of a process.

Which flowchart shape is used for conditional branching such as Yes/No or True/False?

What is a set in Python, and how does it handle duplicate values?

A set is an unordered collection of unique elements that automatically removes duplicates and does not keep items in a specific order.

How do Python tuples differ from Python lists?

Tuples are ordered, immutable collections of items that cannot be modified after creation, whereas lists are flexible and mutable.

What is a dictionary in Python?

A dictionary is an unordered, mutable collection of key-value pairs where each key must be unique and maps to a specific value.

How do you remove an element from a dictionary in Python?

By using variable_name.pop(key) or del variable_name[key].
