Python function print output redirect - variables

Question

Its my first attempt at coding and I've a bit of a snag.
I was wondering if one of you would be able to point me in the right direction for this case..
What I'm trying to do is convert a string from hexadecimal format into readable text.
Following this, I want to run the converted string/text against some regex commands in order to pick out things like email addresses and domains.
I know the codes work individually when testing - but the problem is that when trying to run them together, I am unable to properly assign the print output of the converted string into the variable for me to run the regex commands against.
Any tips or suggestions on how I can get around to properly assigning the converted string into a variable and work on it?
This is part of the code as the rest are options available to convert other format types into readable text:
#!/usr/bin/env python3
import base64
import codecs
import re
import sys
print(" If the data is Hexadecimal and looks similar to this: 48656C6C6F20686F77206172, enter: 2 ")
print("")
decision = int(input("enter the number here: "))
print("")
message = input("Enter the data you wish to have decoded: ")
def decode_hex1(encoded_text):
information = ''
for i in range(len(encoded_text)//2):
information = information +
print(codecs.decode(encoded_text[i*2:i*2+2]0, "hex").decode('utf-8'), end="")
return information
if decision == 2:
output = decode_hex1(message)
match_emails = re.findall(r'[\w.+-]+#[\w-]+\.[\w.-]+', output)
print("The following emails may be of interest to you: ", match_emails)
print("")
domain_regex = r'(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-]{,61}[a-zA-Z0-9])?\.)+[a-zA-Z]{2,6}'
match_domains = re.findall(domain_regex, output)
print("The following domains may be of interest to you: ", (match_domains))
else:
print("Invalid Choice - please check the number and try again")
print("")
print("Done")
