Python Bootcamp in a Day - Python Programming for Beginners - Indexing

The video tutorial explains how to use indexing in Python to access characters in a string. It covers the concept of 0-based indexing, encourages experimentation with code, and demonstrates how to extract substrings. Additionally, it introduces negative indexing, which allows accessing characters from the end of a string.

What is the index of the first character in a Python string?

• 1

• 0

• -1

• 2

Why is it beneficial to experiment with Python code when learning about indexing?

• It helps you memorize the syntax.

• It allows you to understand the behavior of different indices.

• It makes your code run faster.

• It is required to pass Python certification exams.

How can you access the last character of a string using indexing?

• Using index 0

• Using index -2

• Using index -1

• Using index 1

What does a negative index in Python indicate?

• It skips every other character.

• It starts counting from the end.

• It starts counting from the beginning.

• It doubles the character at that position.

Why might you store the index of the last character in a variable?

• To decrease the index value.

• To increase the index value.

• To make the code run slower.

• To avoid recalculating it multiple times.
