Question

I would like to know the easiest way to check it the user typing in a letter versus a number. If the user types in a letter it would give them an error message and give them the question back. Right now I have it so when the user enters a ‘q’ it will exit the script.

if station == "q":
        break
else:
        #cursor.execute(u'''INSERT INTO `scan` VALUES(prefix, code_id, answer, %s, timestamp, comport)''',station)
        print 'Thank you for checking into station: ', station

I need it to loop back to the question asking for the station.

Answer 1

Just using python built-in method

str.isdigit()

SEE http://docs.python.org/library/stdtypes.html

e.g.

if station.isdigit():
   print 'Thank you for checking into station: ', station
else:
   # show your error information here
   pass
