Error :cannot use a string pattern on a bytes-like object

Hy am using Python RegEx to show all internet wirless profiles connected to a computer.There is error (TypeError: cannot use a string pattern on a bytes-like object) in my Second last line pls anyone help to identifi my mistake.Thanks

My Program

import subprocess,re
command = "netsh wlan show profile"
output = subprocess.check_output(command, shell=True)

print(network_names.group(0))

.....................................................

ERROR

line 8, in <module>


 return _compile(pattern, flags).search(string)


TypeError: cannot use a string pattern on a bytes-like object

Solution

Python 3 distinguishes "bytes" and "string" types; this is especially important for Unicode strings, where each character may be more than one byte, depending on the character and the encoding.

Regular expressions can work on either, but it has to be consistent — searching for bytes within bytes, or strings within strings.

Depending on what you need, there are two solutions:

Decode the output variable before searching in it; for instance, with: output_text = output.decode('utf-8')

This depends on the encoding that you are using; UTF-8 is the most common these days.

The matched group will be a string.
Search with bytes by adding a b prefix to the regular expression. A regular expression should also use the r prefix, so it becomes: re.search(br"(Profile\s*:\s)(.*)", output)

The matched group will be a bytes object.
