Python:带有两个变量的if语句

我想知道是否有可能将两个变量放入一个if语句中，每个级别都放在一个块中，包括当前的文本变量和答案变量。我想缩短代码，因为它有太多的“如果”。例如：

if level in easy:
     current_text = easy_level
     answers = easy_answers   

代码如下：

    if level in easy:
        current_text = easy_level
    if level in medium:
        current_text = medium_level
    if level in hard:
        current_text = hard_level
    if level in easy:
        answers = easy_answers
    if level in medium:
        answers = medium_answers
    if level in hard:
        answers = hard_answers
    ask_questions(current_text, answers)

谢谢

简短的回答，是的

if level in easy:
    current_text = easy_level
    answers = easy_answers
elif level in medium:
    current_text = medium_level
    answers = medium_answers
elif level in hard:
    current_text = hard_level
    answers = hard_answers
ask_questions(current_text, answers)

简短的回答，是的

if level in easy:
    current_text = easy_level
    answers = easy_answers
elif level in medium:
    current_text = medium_level
    answers = medium_answers
elif level in hard:
    current_text = hard_level
    answers = hard_answers
ask_questions(current_text, answers)

简短的回答，是的

if level in easy:
    current_text = easy_level
    answers = easy_answers
elif level in medium:
    current_text = medium_level
    answers = medium_answers
elif level in hard:
    current_text = hard_level
    answers = hard_answers
ask_questions(current_text, answers)

if level in easy:
    current_text = easy_level
    answers = easy_answers
elif level in medium:
    current_text = medium_level
    answers = medium_answers
elif level in hard:
    current_text = hard_level
    answers = hard_answers
ask_questions(current_text, answers)

是的，您可以执行类似以下代码的操作

print "Please enter a number between 1 and 20"
enter_num = int(raw_input("> "))

if enter_num >= 1 and enter_num <= 20: 
    print "You have entered a valid number"
    if enter_num % 2 == 0: #test for even/odd
             print "Your number is even"
             print enter_num * enter_num
    elif enter_num % 2 == 1: #test for even/odd
             print "Your number is odd"
             print enter_num * 3
 else:
    print "You've entered an invalid number"

在这种情况下，您可能更喜欢使用dictionary dispatch：

current_text = text[level]
current_answers = answers[level]

。。。其中，

级别

设置为

中的某个值（'easy'、'medium'、'hard'）

。。。或者随便什么。
