从Python字典中提取多组键值对并解答相关统计问询

1. 男演员Nandi Awards总数计算 #

遍历字典中actors下的所有男演员，累加他们的Nandi Awards数量：

movies = {
    'actors': {
        'prabhas': {'knownAs': 'Darling', 'awards': {'nandi': 1, 'cinemaa': 1, 'siima': 1}, 'remuneration': 100, 'hits': {'industry': 2, 'super': 3, 'flops': 8}, 'age': 41, 'height': 6.1, 'mStatus': 'single', 'sRate': '35%'},
        'pavan': {'knownAs': 'Power Star', 'awards': {'nandi': 2, 'cinemaa': 2, 'siima': 5}, 'hits': {'industry': 2, 'super': 7, 'flops': 16}, 'age': 48, 'height': 5.9, 'mStatus': 'married', 'sRate': '37%', 'remuneration': 50},
    },
    'actress': {
        'tamanna': {'knownAs': 'Milky Beauty', 'awards': {'nandi': 0, 'cinemaa': 1, 'siima': 1}, 'remuneration': 10, 'hits': {'industry': 1, 'super': 7, 'flops': 11}, 'age': 28, 'height': 5.9, 'mStatus': 'single', 'sRate': '40%'},
        'rashmika': {'knownAs': 'Butter Milky Beauty', 'awards': {'nandi': 0, 'cinemaa': 0, 'siima': 2}, 'remuneration': 12, 'hits': {'industry': 0, 'super': 4, 'flops': 2}, 'age': 36, 'height': 5.9, 'mStatus': 'single', 'sRate': '30%'},
    }
}

total_nandi = sum(actor['awards']['nandi'] for actor in movies['actors'].values())
print(total_nandi)  # 输出：3

所有男演员获得的Nandi Awards总数为3。

2. 查询被称为Prince的艺人的sRate #

遍历字典中所有艺人，检查knownAs字段是否为"Prince"：

def find_srate_by_known_as(alias):
    # 检查男演员
    for name, details in movies['actors'].items():
        if details['knownAs'] == alias:
            return details['sRate']
    # 检查女演员
    for name, details in movies['actress'].items():
        if details['knownAs'] == alias:
            return details['sRate']
    return None

print(find_srate_by_known_as('Prince'))  # 输出：None

当前字典中没有被称为"Prince"的艺人，无法查询到对应的sRate。

3. 确认被称为Prince的艺人的真实名称 #

遍历所有艺人匹配别称：

def find_real_name_by_known_as(alias):
    # 检查男演员
    for name, details in movies['actors'].items():
        if details['knownAs'] == alias:
            return name
    # 检查女演员
    for name, details in movies['actress'].items():
        if details['knownAs'] == alias:
            return name
    return None

print(find_real_name_by_known_as('Prince'))  # 输出：None

当前字典中不存在被称为"Prince"的艺人，没有对应的真实名称。
