How to Create a Python Length Checker/Filler?

To create a Python length checker/filler, you can use the built-in functions and methods available in Python. Here are the steps to create a length checker/filler:

1. Define a function that takes two arguments: a string and a maximum length. The function will check the length of the string and fill it with a specified character if it is shorter than the maximum length. For example:

def check_and_fill(s, max_length, fill_char=' '):
    if len(s) < max_length:
        fill_length = max_length - len(s)
        s += fill_char * fill_length
    return s

2. The check_and_fill function checks if the length of the input string s is less than the specified maximum length max_length. If the length is less, it calculates the number of characters that need to be filled to reach the maximum length and adds them to the string using the specified fill_char.
3. Test the function by calling it with different inputs and print the output. For example:

s1 = "Hello"
s2 = "World"
s3 = "Python is awesome!"
max_length = 20
fill_char = '*'

print(check_and_fill(s1, max_length, fill_char))
print(check_and_fill(s2, max_length, fill_char))
print(check_and_fill(s3, max_length, fill_char))

4. The output of the function will be the input string padded with the fill character to reach the maximum length. For example, the output of the above code will be:

Hello***************
World***************
Python is awesome!****

That’s it! You have now created a Python length checker/filler that can check the length of a string and fill it with a specified character if it is shorter than the maximum length.
