PYTHON — Shout Function in Python

First, solve the problem. Then, write the code. — John Johnson

Adding a Shout Function in Python

In this tutorial, we’ll learn how to add a “shout” function to a Python module. The function will take a string as input and return a new string with all letters in uppercase. Let’s dive into the code and see how this can be implemented using Python.

Task List for Adding the Shout Function

First, let’s create a task list for adding the “shout” function to the string.py module.

1. Add the Shout Function: Define a function called shout() that takes a single string parameter and returns a new string with all letters in uppercase.
2. Define the Shout Function: Define the shout() function with the pass statement as a placeholder.
3. Specify the Parameter: Add a parameter named string to the shout() function to accept the input string to be shouted.
4. Return Uppercase String: Modify the function to return the input string in uppercase using the .upper() method.

Implementation of the Shout Function

Let’s implement the “shout” function in the string.py module using the defined task list.

# string.py

def shout(string):
    return string.upper()

Testing the Shout Function

Now, let’s test the implemented shout() function by running the module and calling the function with a lowercase string.

# Testing the shout function
import string

shouted_string = string.shout("hello")
print(shouted_string)  # Output: HELLO

By executing the above code, we can confirm that the shout() function successfully converts the input string to uppercase.

Conclusion

In this tutorial, we learned how to add a “shout” function to a Python module. The function takes a string as input and returns a new string with all letters in uppercase. This simple example demonstrates the implementation of a custom function within a Python module.
