[Tutor] Error writing to file...

[Ken G.]

In writing the following program in creating random numbers and writing 
them to the file, I get an type error in writing to file.  I have tried 
number = random(10,99), number = randint(10.99), and number = 
random.random(10,00) and still get various errors of writing to file. 

If I were to REM out the file.write(number) and file.write('\n') lines, 
the program run fine.  Do I need to convert a numeric random number to a 
string number?

TIA,

Ken

PROGRAM:

import random
print ("First Group - Write")
file = open("Numbers.txt","w")
for i in range(1,10):
    number = random.randint(10,99)
    print i, number
    file.write(number)
    file.write('\n')
file.close()

ERROR MESSAGE:
