8. Write a program that reads characters from the keyboard one by one. All lower case characters get stored inside the file LOWER, all upper case characters get stored inside the file UPPER and all other characters get stored inside file OTHERS.

# Code
f1 = open(‘LOWER.txt’, ‘w’)
f2 = open(‘UPPER.txt’, ‘w’)
f3 = open(‘OTHERS.txt’, ‘w’)

c = True
while c:
c = input(‘Enter a character to write or False to terminate the program : ‘)
if c is False:
break
elif c.islower(): # checks for lower character
f1.write(c)
elif c.isupper() # checks for upper character
f2.write(c)
else:
f3.write(c)
