Knowing how to work with and manipulate Python Strings is an essential and important coding skill that needs to be mastered!

This Lab is designed to show you how to work with and manipulate Python Strings:

  • Exercise 1 - Counting: Complete the code used to determine string lengths, and char max and mins
  • Exercise 2 - Finding: Complete the code used to search and index for character sequences within a string
  • Exercise 3 - Formatting: Complete the code used to format strings using various formatting techniques
  • Exercise 4 - Splitting: Complete the code used to split, join, partition, and replace strings

Note: Each exercise has a provided solution to consult with when needed.

Lab Objectives

Upon completion of this Lab, you will be able to:

  • Write Python code to manage and maintain strings
  • Use the terminal to launch and debug Python scripts

You should:

  • Be comfortable with using a browser-based IDE

Lab Environment

This Lab will start with the following AWS resources provisioned automatically for you:

  • A single EC2 instance, named ide.python.platform.instance, which will have a public IP address attached. This instance will host a web-based Python IDE (based on the Visual Code editor).

To achieve the Lab end state, you will be walked through the process of:

  • Using your local browser, access the web-based Python IDE served from the ide.python.platform.instance
  • Completing the following lab exercises:
    • Exercise 1 - Counting
    • Exercise 2 - Finding
    • Exercise 3 - Formatting
    • Exercise 4 - Splitting
