There is an error in script. seed = 'tweer' obj = generate_spaceship(seed) Python can't redefine functions as variables. Seed is a function.

i'm not the author but i frequently code in python and am unable to understand what you're saying from that snipped of code. 1. you can overwrite everything in python 2. seed has been set to a string 3. obj uses the value of previously set 'seed' variable, which should be a string at that point. its not a good idea, like overwriting the id variable, but it should work... and just in case somebody wonders: its still possible to use the "true" seed() by calling it over __builtins__.seed() i did similar stuff previously without realizing and only found out about this after i switched to a real IDE that warned me about overwriting inbuilt functions

  Yes, that's correct. >>> from random import seed >>> seed(10) >>> seed <bound method Random.seed of <random.Random object at 0x24721c0>> >>> seed = 50 >>> seed 50 >>> from random import seed >>> seed <bound method Random.seed of <random.Random object at 0x24721c0>> (You can't get it as __builtins__.seed because it's not a builtin, but you can re-import it from random to get it back.)

  'seed' is explicitly imported on line 18, then overwritten on line 736, and yet it's used as a function on line 526. As far as I can tell, that is an error. >>> from random import seed >>> def f(): return seed(10) >>> seed = 50 >>> f() Traceback (most recent call last): File "<pyshell#4>", line 1, in <module> f() File "<pyshell#2>", line 1, in f def f(): return seed(10) TypeError: 'int' object is not callable >>> I haven't run the script, so take this with a grain of salt. EDIT: Since generate_spaceship is always called with an empty random_seed parameter, this error won't happen when the script is run.
