Need some python code implemented (nonce, ts, ect)

I'm looking for someone who would be able to implement some code in Python. I have a header I need it to be in as it needs to be generated each request. the header would look like so: "myhead={'Accept':'*/*', 'X-Platform':'android', 'X-Language':'en', 'Content-Type':'application/json', 'Authorization': 'MAC id'= "+mac_key +", nonce='+TS+':'+nonce+', ts='+ TS + ', mac='+mac_gen, } For 'Authorization' I need it to be generated when needed, which is usually every request. I have done this in C#, looking for a way to do it with python so all requests would be valid.
