Python - Correct way to get string without ANSI chars and also print pexpect data

Question

Currently, for these few days I have created a working code that works as I would expect, but there is one significant problem that I do not know how to solve.

But let's start from the beginning. I found something like pexpect and I wanted to use it on linux, instead of the usual "os.system". I'm going to use windscribe here...

def connect():
    username = "username1"
    while True:
        child = pexpect.spawn('windscribe account')
        match = child.expect("ee")
        rem = re.compile(r'(\x9B|x1B\[)[0-?]*[ -/]*[@-~]')
        v = rem.sub('', str(child.before.decode('UTF-8')))
        sta = v.split("\n")
        for line in sta:
            if line.startswith("Username:"):
                user = line.replace('Username: ', '')
            if line.startswith("Data Usage:"):
                dataus = line.replace('Data Usage: ', '').replace('GB / 10 GB', '')
        print("The username is: ", username)
        print("Data used: ", dataus)
        if username == user:
           print("the same")
           if float(dataus) > 8:
              print("You used too much data!")
        else:
           print("not the same")
    

Unfortunately, when I try to display the currently logged in user, or check how much the limit has been used, theoretically everything works fine. Displays:

The username is: username1
Data used: 7.79
**not the same**

But when I want to apply it in the program, i.e. compare:

if float(dataus) > 8: I get an error that the string cannot be formatted to float and its preview is: "7.79 \x1b[0m\r" Same with the username you want to compare in:

if username == user:

Theoretically they are the same, but not.

The username is: username1 \x1b[0m\r
Data used: 7.79 \x1b[0m\r

I temporarily got around this with this trick, but I don't quite understand why that code doesn't work if I decode it to utf-8 and I think I created a good regex

for line in sta:
            if line.startswith("Username:"):
                user = line.replace('Username: ', '').replace("\x1b[0m\r", '')
            if line.startswith("Data Usage:"):
                dataus = line.replace('Data Usage: ', '').replace('GB / 10 GB', '').replace("\x1b[0m\r", '')

Question 2 How i can print output from sent command? because now i must cut last two "ee" words, to print whole output ^^. Mean:

child = pexpect.spawn('windscribe account')
match = child.expect("ee")
rem = re.compile(r'(\x9B|x1B\[)[0-?]*[ -/]*[@-~]')
v = rem.sub('', str(child.before.decode('UTF-8')))

Question 3 Is pexpect is good for that usage? Or better way is use ex:

stdoutdata = subprocess.getoutput("windscribe status")
sta = stdoutdata.strip()
if "CONNECTED -- " in sta:
   ...
