[数据结构与算法]python中各种排序

计算字符串长度

def calculate_string_width(strs, pointSize):
    chinese_numb = 0
    other_numb = 0
    for c in strs:
        if ('\u4e00' <= c <= '\u9fa5'):
            chinese_numb += 1
        else:
            other_numb += 1

    string_width = chinese_numb * pointSize + other_numb * pointSize / 2

    return string_width

字典排序

input_data_contact_info_dict = {}

for key in list(input_data.keys()):
    if key in contact_info_filter:
        input_data_contact_info_dict[key] = input_data[key]
input_data_contact_info_dict_sort = {k : v for k, v in sorted(input_data_contact_info_dict.items(), \
                                                              key=lambda items: calculate_string_width(items[1], 1))}

print('model_contact_info_list sort before: ', model_contact_info_list)
model_contact_info_list.sort(key=lambda k: (int(k.get('y', 0)), k.get('width', 0)))
print('model_contact_info_list sort after: ', len(model_contact_info_list), model_contact_info_list)
