python pass string to function

In Python, strings are a fundamental data type that represents sequences of characters. When working with functions, you may need to pass strings as arguments. This tutorial will guide you through the process of passing strings to functions in Python with code examples.
Let's start with a simple example of a function that takes a string as a parameter:
In this example, the greet function takes a single parameter, name, which is a string. When calling the function, provide a string argument within the parentheses.
You can also set default values for string parameters in a function. If an argument is not provided, the default value will be used:
In this case, the greet_default function has a default parameter value of "Guest". If you call the function without providing an argument, it will use the default value.
Functions can also return modified strings. Here's an example of a function that adds a prefix to a given string:
In this example, the add_prefix function takes two parameters, original and prefix, and returns a modified string. You can customize the prefix by providing a second argument when calling the function.
Functions can also operate on strings using various methods. Here's an example of a function that counts the number of vowels in a given string:
In this example, the count_vowels function uses a list comprehension to count the vowels in the input string. The result is then returned and printed.
These examples demonstrate different ways to pass strings to functions in Python. Whether you need to manipulate strings or perform specific operations, understanding how to work with string parameters in functions is essential for effective Python programming.
