Final answer:
In this program, the remove_non_alpha function takes an input string and uses a list comprehension to iterate over each character in the string. The isalpha() method is used to check if a character is alphabetic (a letter). Only alphabetic characters are included in the result, and the join method is then used to concatenate them into a single string.
Step-by-step explanation:
Certainly! Here's a simple Python program that removes all non-alpha characters from the given input:
python
Copy code
def remove_non_alpha(input_string):
result = ''.join(char for char in input_string if char.isalpha())
return result
# Example usage:
input_text = "Hello, 123 World!"
cleaned_text = remove_non_alpha(input_text)
print(cleaned_text)
In this program, the remove_non_alpha function takes an input string and uses a list comprehension to iterate over each character in the string. The isalpha() method is used to check if a character is alphabetic (a letter). Only alphabetic characters are included in the result, and the join method is then used to concatenate them into a single string.
In the example usage, the input text is "Hello, 123 World!", and the output will be "HelloWorld" because all non-alpha characters, such as commas and digits, have been removed.
