单项选择题供选答案有四项:A、B、C、D 输入 10道单项选择题的答案 分别计算答案中四个选项的个数 输入格式: 一个字符串，10道单项选择题的答案，以空格隔开。 输出格式: 四行输出，分别输出A选项B选项C选项D选项的个数

好的，我理解了你的问题。以下是Python代码实现：

answers = input().split()  # 输入10道选择题的答案，以空格隔开

count = {'A': 0, 'B': 0, 'C': 0, 'D': 0}

for ans in answers:
    count[ans] += 1  # 统计每个选项出现的次数

print(count['A'])
print(count['B'])
print(count['C'])
print(count['D'])

你可以将10道选择题的答案输入，程序会输出四行，分别是A、B、C、D选项的个数。注意，输入的答案字符串中每个字符都应该是大写的A、B、C、D中的一个。

单项选择题供选答案有四项：A、B、C、D。输入10道单项选择题的答案，分别计算答案中四个选项的个数。 输入格式: 一个字符串，10道单项选择题的答案，以空格隔开。 输出格式: 四行输出，分别输出A选项B选项C选项D选项的个数。

好的，那么我们可以编写如下的Python程序实现：

# 读取用户输入
answers = input().split()

# 定义选项计数器
option_count = {
    "A": 0,
    "B": 0,
    "C": 0,
    "D": 0
}

# 统计选项个数
for ans in answers:
    option_count[ans] += 1

# 输出结果
for option, count in option_count.items():
    print(f"{option}: {count}")

在这个程序中，我们首先读取用户输入的答案字符串，并使用`split`函数将其转换为一个由答案组成的列表`answers`。接着，我们定义了一个字典`option_count`来统计每个选项出现的次数。使用`for`循环遍历了答案列表`answers`，并使用`option_count`字典来统计每个选项出现的次数。最后，我们使用`for`循环遍历`option_count`字典，输出结果。

运行这个程序，就可以得到每个选项出现的次数了。注意，用户输入的答案字符串必须严格按照题目要求的格式，即每个答案之间用空格隔开。
