a = 0 # FIRST, set the initial value of the variable a to 0(zero).

while a < 10: # While the value of the variable a is less than 10 do the following:

a = a + 1 # Increase the value of the variable a by 1, as in: a = a + 1!

print(a) # Print to screen what the present value of the variable a is.

# REPEAT! until the value of the variable a is equal to 9!? See note.

# NOTE:

# The value of the variable a will increase by 1

# with each repeat, or loop of the 'while statement BLOCK'.

# e.g. a = 1 then a = 2 then a = 3 etc. until a = 9 then...

# the code will finish adding 1 to a (now a = 10), printing the

# result, and then exiting the 'while statement BLOCK'.
