Generating Perfect Squares python

I am trying to write the simplest code possible that will continuously print out Perfect Squares. My code so far reads this

x = 1
y = 1
while True:
    final = x * y
    print final
    x = x + 1
   y = y + 1

When I run it, I get a syntax error. The red bit is on the "final" in "print final"

Apologies if it is a really basic error, but I'm stumped.

Thanks for taking the time to read this

I would reccomend using Python 3 if you're not already. Also, as x and y are the same value at all times you only need one of them. So instead of reading:

x = 1
y = 1
while True:
    final = x * y
    print final
    x = x + 1
    y = y + 1

You should write:

x = 1

while True:

    final = x * x

    print(final)

    x = x + 1

Hope this helped! Jake.

I assume you're using Python 3. print is now a function in Python 3.

Do print(final) instead of print final.

Also, it seems like your x and y values are holding the same thing. Why not discard one of them and use just one?

x = 1
while True:
    final = x * x
    print(final)
    x = x + 1

Or better yet, use the builtin exponentiation operator **.

x = 1
while True:
    final = x **2
    print(final)
    x += 1

Also, your code seems to be going into an infinite loop. You may need a condition to break it.

For example, if you want to break when x reaches 10, just add a condition in the while loop, like follows:

x = 1
while True:
    final = x **2
    print(final)
    x += 1
    if x == 10:
        break

OR Specify a condition in the whilestatement, like follows:

x = 1
while x < 10:
    final = x **2
    print(final)
    x += 1

OR Use a for loop.

for i in range(10):
    print(i**2)

In Python 3, print is no longer a statement but a function, so you must enclose what you want to print in parentheses:

print(final)

Here's a link about the function.

You also have an IndentationError, y = y + 1 should be given a space.

And you can simplify that to y += 1 (which is the same thing, in regards to integers)

You can also add a condition to the while-loop:

x = 0
while x < 5:
    print x ** 2
    x += 1

Prints:

0
1
4
9
16
