Outdated code from a tutorial. Can't figure it out - pygame

Question

I was following a tutorial about how to 3D render objects in pygame. However it seems that the code is outdated and I don't know how to fix it.
I've spent quite a bit of time looking for the solution, but to no avail, as I don't know what I'm looking for.
def rotateX(self, (cx,cy,cz), radians):
for node in self.nodes:
y = node.y - cy
z = node.z - cz
d = math.hypot(y, z)
theta = math.atan2(y, z) + radians
node.z = cz + d * math.cos(theta)
node.y = cy + d * math.sin(theta)
It is supposed to show me a game window with a cube that I can move around and such, but instead it throws me an error.
Traceback (most recent call last):

SyntaxError: invalid syntax

Answer 1

Aside from the fact that your error message isn't pointing to the code you've pasted (def scale vs def rotateX). They share the same issue.
It's an older Python2 syntax. Simply just replace it with rotateX(self, cx, cy, cz, radians) or rotateX(self, axies, radians) and add a line that does cx, cy, cz = axies at the start of the function. Either way, Python3 simply just doesn't take a tuple expansion by default. At least not in this way.
So either do:
def rotateX(self, cx, cy, cz, radians):
for node in self.nodes:
y = node.y - cy
z = node.z - cz
d = math.hypot(y, z)
theta = math.atan2(y, z) + radians
node.z = cz + d * math.cos(theta)
node.y = cy + d * math.sin(theta)
And make sure you update the call to the rotateX function, or you could do:
def rotateX(self, axies, radians):
cx, cy, cz = axies
for node in self.nodes:
y = node.y - cy
z = node.z - cz
d = math.hypot(y, z)
theta = math.atan2(y, z) + radians
node.z = cz + d * math.cos(theta)
node.y = cy + d * math.sin(theta)
And you shouldn't need to update the call to the function in any way. There's probably a neater way to do the same thing as Python2 did. But I have never needed or used it. But this should solve your problem at least.
Oh, and submit a issue report to Pygame. They should be aware or instructed if the instructions are off/old.
