euler Module¶
This is the main module for Project Euler, it provides some high-level functionality via a command-line application.
By starting a new problem, its description will be downloaded into a skeleton Python module which
conforms to the API used in this project; the module will be placed at solutions/problemX.py for problem X. You
must provide a function solve() which computes and returns the answer. Once you have successfully submitted the
correct answer to the Project Euler website you should save that answer into the
expected_answer member. This will be used to check the ongoing correctness of your solution.
While developing and testing your solution, you’ll want to run your code. To compute the answer to problem X using
your solution you would exercise the solve function.
Note
both start and solve commands take an optional problem identifier; if this is not provided, you will
be prompted for one on the standard input.
Finally, you may want to [re-]validate all solutions (to check you haven’t broken anything) via the validate
function.
Program Synopsis¶
usage: euler.py [-h] {start,solve,validate} ...
Positional Arguments¶
| command | Possible choices: start, solve, validate |
Sub-commands:¶
start¶
Start a new Project Euler problem
euler.py start [-h] [n]
Positional Arguments¶
| n | problem number (default: prompt user for input) |
euler – Command Line Interface¶
-
euler.main()¶ Main program entry point
-
euler.solve_problem(selection)¶ Dynamically load and run solution for a selected Project Euler problem
-
euler.start_problem(selection)¶ Create a template solution Python file for a selected Project Euler problem
The Python file will be populated by the problem description and boilerplate needed by this project.
