If you want another option:

s='fafaf fadfa fafa fa-fa faf_afa@gs!'
s.translate(str.maketrans('', '','_-@ !'))

Output:

'fafaffadfafafafafafafafags'

The third argument of str.maketrans(), it must be a string, whose characters will be mapped to None in the result. That means they will be deleted.

And the documents: str.maketrans() and str.translate()

Try this:

import re

letters_only = re.sub("[^a-zA-Z0-9]", "", your_string)

@Rohit has a good answer if if you want it faster do a list comprehension:

print(''.join([i for i in s if i.isalnum()]))

Demo:

s='fafaf fadfa fafa fa-fa faf_afa@gs!'
print(''.join([i for i in s if i.isalnum()]))

Output:

fafaffadfafafafafafafafags

You can use .isalnum()

''.join(e for e in a if e.isalnum())

Try this:

import re

input_ = 'fafaf fadfa fafa fa-fa faf_afa@gs!' 
input_ = re.sub('[^0-9a-zA-Z]+', '', input_)
