Python 3 for Beginners: Introduction to Functions and Built-in Functions in Python

The video tutorial introduces functions in Python, focusing on the print and Len functions. It explains how functions can accept arguments and return data. The print function is demonstrated with variables and direct string inputs. The Len function is introduced to calculate the length of strings, with examples showing its use with variables and direct calls. The tutorial emphasizes understanding function calls and the evaluation order in Python.

What is a function in Python?

• A block of code that performs a specific task

• A variable that stores data

• A conditional statement

• A type of loop

What does the print function do in Python?

• Executes a loop

• Calculates the length of a string

• Stores a value in a variable

• Displays a value on the screen

How can you print a variable's value using the print function?

• By using the variable name within the print function

• By using the variable name directly

• By using the Len function

• By assigning the variable to another variable

What does the Len function return when given a string?

• The first character of the string

• The last character of the string

• The string in reverse order

• The number of characters in the string

How can you use the Len function without assigning its result to a variable?

• By using it in a conditional statement

• By storing it in a list

• By passing it directly to the print function

• By using it within a loop
