帮助计数和列出

  • 772

请帮助解决问题。

鉴于：

腿骨列表。有必要迭代列表并找到输入的单词与列表中的单词的匹配。两次尝试，每次尝试后立即响应。此外，您需要计算列表中有多少项目。

这是我生的（我无法以任何方式计算总数）：

foot_bones = ["calcaneus", "talus", "cuboid", "navicular", "lateral cuneiform",
         "intermediate cuneiform", "medial cuneiform"]
total = 0
guess = ""
def bones_func (guess, foot_bones, total):
guess = input ("Enter the name of the foot bone: ")
for bone in foot_bones:
    if guess.lower()== bone:
        print ("Correct")
        total += foot_bones.count(bone)
    else:
        print ("Incorrect")
        total += foot_bones.count(bone)

bones_func (guess, foot_bones, total)
bones_func (guess, foot_bones, total)
print (total)

这是我在互联网上找到的，完全让我陷入了昏迷：

foot_bones = ["calcaneus", "talus", "cuboid", "navicular", "lateral cuneiform", "intermediate cuneiform", "medial cuneiform"]

def foot_bones_quiz(guess, answer):
total_bones = 0
for bones in answer:
    total_bones += bones.count(bones)
    if guess.lower() == bones.lower():
        return True
    else:
        pass
return False
print("Total number of identified bones: " + str(total_bones))

user_guess = input("Enter a bone: ")
print("Is " + user_guess.lower() + " a foot bone?" , foot_bones_quiz(user_guess, foot_bones))
user_guess = input("Enter another bone: ")
print("Is " + user_guess.lower() + " a foot bone?", foot_bones_quiz(user_guess, foot_bones))

我不清楚猜测变量在解决方案中的来源？它们与 user_guess 有什么关系？答案变量与foot_bones 有何关系？如何在列表中进行完整计数？谢谢

    我不清楚猜测变量在解决方案中的来源？

    def foot_bones_quiz(guess, answer):函数变量的描述是函数guess的参数。

    它们与 user_guess 有什么关系？答案变量与foot_bones 有何关系？

    这里函数被调用，它foot_bones_quiz(user_guess, foot_bones)进入参数，进入变量guessuser_guessanswerfoot_bones

    如何在列表中进行完整计数？

    该列表有一个方法count。您需要将骨骼的名称放入计数中并获得结果。

    例子：

    foot_bones = ["calcaneus", "talus", "cuboid", "navicular", "lateral cuneiform", "intermediate cuneiform", "medial cuneiform"]

bone = 'lateral cuneiform'
print(foot_bones.count(bone))  # 1

    PS。我不是医生，所以我不知道它们是"lateral cuneiform", "intermediate cuneiform", "medial cuneiform"单独的骨头还是搜索也应该通过部分巧合找到，例如：

    print(find_bones(foot_bones, 'cuneiform'))  # 3

    附言 如果您的任务是手动编写搜索功能，那么您需要知道функции：условия和циклы。

    def count_bones(bone_list, target_bone):
    # Для регистронезависимого поиска
    target_bone = target_bone.lower()

    number = 0

    for bone in bone_list:
        # Элементы списка тоже приводятся в тот же регистр, что target_bone
        if bone.lower() == target_bone:
            number += 1

    return number


foot_bones = ["calcaneus", "talus", "cuboid", "navicular", "lateral cuneiform", "intermediate cuneiform", "medial cuneiform"]
print(count_bones(foot_bones, 'cuboid'))  # 1
