what will be the correct syntax of ,I m trying to add given timezone to the current UTC time so that i can get the time according to given time zone [closed]

I was trying to add give timezone to the current UTC time but getting a syntax error and I m not able to fix it ..my desired output is-"2021-03-17T17:35:31.621Z+0530" and the condition is that timezone will be given by user ,it's not fixed and my code in python is:

import datetime,time  sent_at=datetime.datetime.utcfromtimestamp(time.time())+t="+0530"  hours =int(t[1:3])  minutes =int(t[3:5])          v= hours*60*60 +minutes*60    need_time=time.time()+v   result_time=datetime.datetime.utcfromtimestamp(need_time)).strftime('%Y-%m-%dT%H:%M:%S.%f')     [:-3]+'Z'+'+0530'  

...... I am doing this much code because I don't understand how to add a string type timezone to a current UTC time...and after all this, I am getting syntax error
