Python 统计yaml文件中数字出现的次数

import yaml
# 读取yaml文件数据
f = open(‘test.yaml‘)
data = yaml.load(f, Loader=yaml.FullLoader)
print(data)

# 获取出现频次最高数字
def max_list(lt):
    global max_str
    temp = 0
    for i in lt:

        if lt.count(i) > temp:
            max_str = i
            temp = lt.count(i)

    return max_str, temp

# 统计每个数字出现的频次
dict = {}
keys_1 = []
keys_2 = []

for key in data:
    if 0 < int(key) <= 10:
        keys_1.append(key)
        dict[key] = dict.get(key, 0) + 1
    elif 10 < int(key) < 50:
        keys_2.append(key)
        dict[key] = dict.get(key, 0) + 1

print(dict)
print(‘0-10出现次数为{},数字为：{}‘.format(len(keys_1), keys_1))
print(‘10-50出现次数为{},数字为：{}‘.format(len(keys_2), keys_2))
print(‘出现最多次数的为‘, max_list(data))
