pythondev | help | I’ll try my best! All of the issues you were running into were syntax errors. It would likely be a good idea to check out the tutorial on the official docs site: <https://docs.python.org/3/tutorial/index.html> — The specific syntax errors you had were: 1. Invalid/inconsistent tabs; Python uses tabs to denote blocks of code (effectively “scope”), whereas other languages use things like curly braces (`{` and `}`) to denote blocks of code. 2. The `assert` keyword has a specific invocation pattern. You need an expression to assert, and more generally `assert`ing an object will _evaluate_ your expression in an attempt to confirm that it is “Truthy” (i.e. using `bool(expression)` will return `True`), otherwise it will raise an `AssertionError`. | 2019-03-14T14:11:13.715800 | Carina | pythondev_help_Carina_2019-03-14T14:11:13.715800 | 1,552,572,673.7158 | 13,645 |
pythondev | help | In your case specifically, you’re using the python shell, which is an interactive program where you type code directly into the interpreter. It’s still a python interpreter and still requires valid python syntax, so tabs are still a requirement. The tricky thing about the python shell is that it’s not really practical to build any significant/major behavior through the interactive interpreter, which is why I suggested putting your code in a file instead and running it using the `python my_tests.py` command. | 2019-03-14T14:12:51.716000 | Carina | pythondev_help_Carina_2019-03-14T14:12:51.716000 | 1,552,572,771.716 | 13,646 |
pythondev | help | Further, the `if __name__ == '__main__': test_all()` line is what tells python what code to run. This is more or less standard boiler plate for python applications/code, it’s somewhat analogous to other language “main” functions. For example, in java you’d use `public static void main(String[] args)`, in C it’s `int main()`, etc. etc. | 2019-03-14T14:15:52.716200 | Carina | pythondev_help_Carina_2019-03-14T14:15:52.716200 | 1,552,572,952.7162 | 13,647 |
pythondev | help | I hope that’s clear, but definitely let me know if I can clarify this further. | 2019-03-14T14:19:01.716400 | Carina | pythondev_help_Carina_2019-03-14T14:19:01.716400 | 1,552,573,141.7164 | 13,648 |

pythondev | help | I’m writing a simple example of a HashTable. I want my HashTable to accept any key which is `Hashable`, instead of having to limit myself to lets say an `int`.
Instead of using the built in `__hash__` function, I want to roll my own simple one, for illustrative purposes. Can someone help me with taking some `Hashable` object and overriding its `__hash__` function?
```
from typing import Hashable, Any
class HashTable:
"""A horribly simple HashTable implementation.
"""
# Where we store our HashTable's keys -> value mapping
storage = [] # type: [int, List[(Hashable, Any)]]
def hash(self):
return self.__attrs % 42
def __getitem__(self, key_to_look_up: Hashable) -> Any:
"""Some text about the function
"""
def __setitem__(self, key_to_store: Hashable, value: Any):
"""Some text about the function
"""
key_to_store.__hash__ = self.hash.__get__(key_to_store, key_to_store.__class__) # this is failing
```

pythondev | help | Hmm, moving self to the first param didn't fix my issue. The error is `NameError: global name create_board is not defined` I'm testing the gameOfLife function by simply calling `gameOfLife([[0,1,1,1],[0,0,1,1],[1,1,0,1],[0,0,0,0]])` | 2019-03-15T14:51:11.765200 | Richelle | pythondev_help_Richelle_2019-03-15T14:51:11.765200 | 1,552,661,471.7652 | 13,697 |

pythondev | help | You may have already fixed it, but in calling your methods internally, you should be doing like `self.create_board(board)` instead of using `self` as a calling parameter, since again, they're associated with a particular object. | 2019-03-15T14:57:33.768500 | Sasha | pythondev_help_Sasha_2019-03-15T14:57:33.768500 | 1,552,661,853.7685 | 13,702 |
