Data Science and Machine Learning (Theory and Projects) A to Z - Function and Module in Python: Input Arguments

The video tutorial explains the concept of dynamic functions in programming, focusing on how functions can change behavior based on input arguments. It demonstrates defining a function that prints messages depending on the input type, implementing type checking, and highlights the benefits of using functions with arguments. The tutorial concludes with an introduction to functions that accept multiple arguments, setting the stage for more complex tasks.

What is the primary advantage of using arguments in functions?

• They limit the function's capabilities.

• They allow functions to perform dynamic tasks.

• They make functions harder to understand.

• They make functions static.

In the example provided, what does the function 'print_message' do?

• It prints the message 'success' only.

• It does not print anything.

• It prints any message passed to it as an argument.

• It prints a fixed message.

Why is it recommended to use docstrings in functions?

• They are mandatory for function execution.

• They help in understanding the function's purpose.

• They make the function run faster.

• They are required for syntax correctness.

What does the function do if the input is not a string?

• It prints the input as it is.

• It converts the input to a string.

• It ignores the input.

• It prints a message indicating the input is not a string.

How can you check the type of an input in a function?

• By using the 'len' function.

• By using the 'type' function.

• By using the 'print' function.

• By using the 'input' function.

What is the benefit of writing a function that handles multiple arguments?

• It restricts the function to a single task.

• It makes the function harder to debug.

• It allows the function to perform more complex tasks.

• It makes the function less flexible.

What is the role of the 'isinstance' function in the example?

• To check if the input is a string.

• To check if the input is a number.

• To convert the input to a string.

• To print the input directly.
