In this lesson, we learn how to use the find function to search for subsets in a string. We also look at how to replace subsets in a string. Ready to be a Python Expert?

Now we look at the title(), upper() and lower() functions that we can use for strings. Learn how to check for the case of a string and do conversions between the different cases.

In this lesson, we learn how to use the format operator to dynamically change the information printed on the screen.

In this assignment, you will learn how to search for the index of multiple instances of a subset in a string.

Functions are a great way to modularize your code and make it easily reusable. Let's get started with Functions in Python!

Learn how to create functions with multiple inputs. With this, you will be able to easily make use of functions to modularize your code.

In this video, we will relook at the recursive approach to compute the Factorial of a number. We will analyze the recursive calls in-depth to understand what is happening.

In this video we look at the if, elif, else sequence of checks. This extends upon the Assignment 2 code that you have done.

We wrap-up this App by adding the Accelerometer Sensor and getting the sensor to trigger the Text-to-Speech Converter.

In this video, you will be introduced to the for-loop in Python. See how easy it is to get it done!

In this lesson, we see how we can set the start and step values for the range parameters. Want to be a Python Pro?

We now look at Nested for-loops. Let's learn how the different loop counters change as we go through the code.

In this lesson, we look at how we can use the continue and break statements to alter the operation of a loop.

In this video we explore the "type" of variables. We also see how to perform a rounding to the nearest integer.

The first thing we need to do to get started with Scratch is to Create a New Account (if you don't already have one). Once we are done with that, explore and get excited! :)

This video provides installation instructions for Python. Once that is done, we play around with the development tool to have an idea on how Python works with numbers and characters.

The first thing we need to do to get started with Python is to download the software and install it. Once we are done with that, explore and get excited! :)

In this lesson, we will learn how we can create our own file and write some Python code that will then run in our Shell. We will also be looking at the 'print' command to send information to the shell.

Here we discuss the "if" statement in Python and how we can use it to selectively execute code.

In this lesson, we learn about the nested "if" statements to see how we can have multiple layers of checks for our data.

In this class, we introduce you to Loops using the "while" statement. Learn how to create a loop that executes statements continuously based on a logic check.

This assignment reviews the concepts of the if-elif-else sequence of checks. Make sure you try out the question before looking at the video! :)
