When I try to start Read.py from lesson 19 I get following error
/home/pi/Documents/Adeept_RFID_Learning_Kit_Python_Code_for_RPi-master/19_RFID/MFRC522-python/MFRC522.py:113: RuntimeWarning: This channel is already in use, continuing anyway.  Use GPIO.setwarnings(False) to disable warnings.
  GPIO.setup(22, GPIO.OUT)

The warning is because the status of the GPIO is not cleared after running the program of the previous course, and it will not affect the operation of the program. The error may be that the MFRC522 library have not been installed, please refer to the manual.
