In the fixed length string i.e "a0000",last 4 bits i.e "0000" should be replaced by the user provided value ( the value is between 0001 + f f f f ) . I intend to form final_string using a fixed_string and an user provided user_string
Example: fixed_string = "a0000" user_string ='1' final string = fixed_string and user_string Example : "a0000" and "1" => a0001 "a0000" and "aa" => c00aa PS : "and" this is not logical and it's just for example If I concatenation using + or += or it's append the value at the end of the string >>> "a0000" + "1" ===> expected was a0001 'a00001' I am on python 2.7 and Linux , any ideas that you recommend to handle this Regards, Ganesh -- https://mail.python.org/mailman/listinfo/python-list
