本文将介绍一款用 Python 编写的帮助程序员编写 Python 考试题目的应用程序。该应用程序包括以下功能:
该应用程序能够大大提高编写 Python 考试题目的效率,同时也能够保证题目的多样性和难度。
该应用程序主要采用了 Python 的随机生成函数的库 random 和字符串操作库 string。
具体实现流程如下:
以下是利用 Flask 框架实现的三个 API:
@app.route('/generate_function')
def generate_function():
functions = ['abs', 'all', 'any', 'bin', 'bool', 'breakpoint', 'bytearray', 'bytes', 'callable', 'chr', 'classmethod', 'compile', 'complex', 'delattr', 'dict', 'dir', 'divmod', 'enumerate', 'eval', 'exec', 'filter', 'float', 'format', 'frozenset', 'getattr', 'globals', 'hasattr', 'hash', 'help', 'hex', 'id', 'input', 'int', 'isinstance', 'issubclass', 'iter', 'len', 'list', 'locals', 'map', 'max', 'memoryview', 'min', 'next', 'object', 'oct', 'open', 'ord', 'pow', 'print', 'property', 'range', 'repr', 'reversed', 'round', 'set', 'setattr', 'slice', 'sorted', 'staticmethod', 'str', 'sum', 'super', 'tuple', 'type', 'vars', 'zip']
name = ''.join(random.choices(string.ascii_lowercase, k=8))
params = ', '.join(random.choices(string.ascii_lowercase, k=random.randint(1,5)))
body = ''.join(random.choices(string.ascii_uppercase, k=random.randint(50,100)))
return f"def {name}({params}):\n {body}"
@app.route('/generate_missing_code')
def generate_missing_code():
templates = ['for i in range({}):', 'if {} == {}:']
missing_index = random.choice([0,1])
missing = 'range(10)' if missing_index == 0 else ('a', 'b')
answer = 'i' if missing_index == 0 else 'a'
code = random.choice(templates).format(missing[0], missing[1])
return f"{code}\n pass # replace this line with your code\n\n# answer: {answer}"
@app.route('/generate_code_quiz')
def generate_code_quiz():
templates = ['{} = {}{}{}', '{} = {}({})', '{}({})\n\n{}()']
template_index = random.randint(0,2)
if template_index == 0:
options = [chr(i) for i in range(ord('A'), ord('A')+4)]
correct_index = random.randint(0,3)
correct_option = options[correct_index]
options.remove(correct_option)
a, b, c = random.choices(string.ascii_uppercase, k=3)
code = random.choice(templates).format(a, b, c, options[0])
code += f"\n{b}({a}, {c})\n\n{b}({c}, {a})"
elif template_index == 1:
options = [abs, len, max, min]
correct_index = random.randint(0,3)
correct_option = options[correct_index].__name__
options = [o.__name__ for o in options if o != options[correct_index]]
a, b = random.choices(string.ascii_uppercase, k=2)
args = [random.randint(1,9), random.randint(1,9)]
code = random.choice(templates).format(a, correct_option, args[0], args[1])
code += f"\n\n{b}({a}, {args[0]}) == {correct_option}({a}, {args[0]})\n{b}({args[1]}, {a}) == {correct_option}({args[1]}, {a})"
else:
options = [i for i in range(10)]
correct_index = random.randint(0,3)
correct_option = options[correct_index]
options = [o for o in options if o != correct_option]
a, b = random.choices(string.ascii_uppercase, k=2)
code = random.choice(templates).format(a, b)
code += f"\n\n{a} = {correct_option}()\nprint({a})\n\n{a} = {options[0]}()\nprint({a})\n\n{a} = {options[1]}()\nprint({a})"
options.insert(correct_index, correct_option)
options = '\n'.join([f"{chr(65+i)}. {o}" for i, o in enumerate(options)])
return f"{code}\n\nOptions:\n{options}\n\nAnswer: {chr(65+correct_index)}"
flask run
启动本地服务器;localhost:5000/generate_function
、localhost:5000/generate_missing_code
和 localhost:5000/generate_code_quiz
,即可查看返回的 Python 函数、Python 代码缺失部分和 Python 代码填空题。
