String Manipulation Concepts in Programming

The video tutorial explores basic string manipulation, including extracting, changing, and concatenating characters in strings. It provides real-world examples such as formatting names in online forms, parsing text in search engines, and abbreviating train station names for tickets. The tutorial also covers various string manipulation commands and their syntax, with a focus on Python.

What is the primary purpose of string manipulation?

• To store strings in a database

• To delete strings

• To manipulate, extract, or change characters in a string

In an online form, why might string manipulation be necessary?

• To ensure the first letter of each name is capitalized and the rest are lowercase

• To delete the entered name

• To change the entered name to numbers

• To store the name in a different format

How does a search engine use string manipulation?

• To store search queries in a database

• To convert search queries to uppercase

• To extract and manipulate parts of the search query to provide a sensible output

• To delete search queries

Why might train station names need to be abbreviated?

• To make them easier to remember

• To fit on a printed ticket

• To store them in a database

• To convert them to numbers

What does the .length command do?

• Extracts a substring

• Returns the length of a string

In Python, what command is used to get the length of a string?

• length()

• len()

• count()

• size()

What is the Python equivalent of the ASC command?

• asc()

• char()

• ord()

• chr()
