lower = open("LOWER.txt" , "w" )
other = open ("OTHER.txt" , "w")

while True :
    user = input("Enter a charracter (for exit enter quit ): ")
    if user == "quit" or user == "Quit" :
        break
    elif user.isupper() :
        upper.write( user + " " )
    elif user.islower( ) :
        lower.write( user + " " )
    else :
        other.write( user + " " )

upper.close()
lower.close()
other.close()

print("Thankyou")
