Challenge 6
this is a big jump from the previous challenges, take your time with it
You are working on a database system for controller input and have been asked to make a series of variable queries to the system. Being the smart programmer you are, you decide to write a script that will interpret the data and return what is relevant.
controlScheme is a list of dictionaries which each have the following schema
{
"id": int, // the controller id of the control
"button": int, // the button id of the control
"descripton": str // a description of what the control is for
}
A schema is just a way of saying what you can expect the data to be
Problem 1
Using higher order functions list map and filter, create a function called getDesc that takes a controlScheme and returns all of its descriptions in a list. You are given sample dataset below , but are encouraged to expand and try other customized datasets.
controlScheme1 = [
{"id": 2, "button": 1, "description": "fire"},
{"id": 2, "button": 2, "description": "intake"},
{"id": 1, "button": 4, "description": "climb"},
{"id": 3, "button": 2, "description": "fudge up"},
{"id": 3, "button": 3, "description": "fudge down"}
]
controlScheme2 = [
{"id": 0, "button": 1, "description": "up"},
{"id": 0, "button": 2, "description": "left"},
{"id": 0, "button": 3, "description": "down"},
{"id": 0, "button": 4, "description": "right"},
{"id": 1, "button": 1, "description": "jump"},
{"id": 1, "button": 2, "description": "shoot"},
{"id": 1, "button": 3, "description": "duck"},
{"id": 1, "button": 4, "description": "run"}
]
def getDesc(controls) -> list[str]:
pass
Problem 2
Like above, except expand on to return a set of ids. Note that a set enforces that there are no duplicates to the id. Also write a function that returns a sorted list of all the buttons. If there are duplicate buttons, keep them.
For sorting a list, you can mutably sort a list with li.sort() example below:
li = [2, 1, 3, 4, 0]
li.sort()
print(li) # [0, 1, 2, 3, 4]
use the following starter for the problem:
controlScheme1 = [
{"id": 2, "button": 1, "description": "fire"},
{"id": 2, "button": 2, "description": "intake"},
{"id": 1, "button": 4, "description": "climb"},
{"id": 3, "button": 2, "description": "fudge up"},
{"id": 3, "button": 3, "description": "fudge down"},
]
controlScheme2 = [
{"id": 0, "button": 1, "description": "up"},
{"id": 0, "button": 2, "description": "left"},
{"id": 0, "button": 3, "description": "down"},
{"id": 0, "button": 4, "description": "right"},
{"id": 1, "button": 1, "description": "jump"},
{"id": 1, "button": 2, "description": "shoot"},
{"id": 1, "button": 3, "description": "duck"},
{"id": 1, "button": 4, "description": "run"}
]
def getIds(controls) -> set[int]:
pass
def getButtons(controls) -> list[int]:
pass
Problem 3
implement a moving weighted moving average generator function. The function has type signature: (terms: float) => ((term: float) => float)
This means that the function should take as input a number of terms to average at most, and then that returned function should take an argument to add to the moving average, and return the moving average.
def movingGenerator(terms: float):
def average(term: float):
pass
return average
avg5 = movingGenerator(5)
print(avg5(1)) # => 1
print(avg5(3)) # => 2
for i in range(7):
print(avg5(i)) # should print out 1.33, 1.25, 1.4, 1.8, 2.0, 3.0, 4.0
