how to remove non alphanumeric characters in python

Of course, user. I'd be happy to help. What's your question?

You can use the 'isalnum()' string method combined with a list comprehension to create a new string without non-alphanumeric characters. Here is how you can do it: ```python input_string = 'your_string_here!' cleaned_string = ''.join(char for char in input_string if char.isalnum()) ``` The 'isalnum()' method checks if all characters in a string are alphanumeric (letters or numbers). 'join()' then concatenates all of the alphanumeric characters into a new string without the non-alphanumeric characters.

That's a good question. To preserve spaces, you can add an extra condition in the comprehension like this: ```python input_string = 'your string here!' cleaned_string = ''.join(char for char in input_string if char.isalnum() or char.isspace()) ``` This way, the 'isspace()' method will preserve all space characters in your string while still removing other non-alphanumeric characters.
