In Python it is easy to convert a number as a string: You can just do

str(90)

https://docs.python.org/3/library/functions.html#func-str

Then in the Arduino code, you can use

parseInt()

https://www.arduino.cc/en/Serial/ParseInt

Or you can just send binary data over the serial line. If your number is always between 0 and 255, you can just send one byte. Otherwise you will have to send the number in several bytes.
