crawler = CTFCrawler()
# crawler.self_load("test_ctf", "https://ctfd.based/site", "****************************************************************", "./test_ctf")
crawler.load("./test_ctf.json")
print("load")
print(crawler.important)
res = crawler.get_challenges()
print("get_challenges")
crawler.download_challenges()

you can choose one option between load and self_load. load is loading from file and self_load is loading from user input.
