catch certain text in file.txt and parse into python file as input

Question

how do i extract certain word in bold below and store the value as input? i managed to get url value as it has referer: text, i would like take value that starting from 1st until it meet '=' sign that is username and continue to catch text start from '&' until '=' which is password?

username=hello&password=test1

Is it always like 5? Is the value always `username` and `password`? — Harshal Parekh, Mar 27 '20 at 17:56
@HarshalParekh it always in line 5 but the username and password is variables/changeable. that why i want to get text in line 5 from 1st to '=' sign and continue from '&' sign to '=' sign..that store as 2 variables respectively.. — jane90, Mar 27 '20 at 18:17

for i, line in enumerate(f):  
    # line 5
    if i == 4:
        # get the value from the start of the string to the first "="
        username = line[:line.index('=')]

        # get the value starting from the "&" to the second "="
        password = line[line.index('&') + 1:line.index('=', line.index('=') + 1)]

        print(username, password)

i know if we have static 'username' and 'password' text, but 'username' and 'password' are not static.But 'username' sometime maybe can be uname' and so on.. – jane90 Mar 27 '20 at 18:21
Then you can use the same logic on line 5. You can check my edit. – Harshal Parekh Mar 27 '20 at 18:22
