- 有時(shí)候?qū)懸粋€(gè)類顯得大材小用,你可以了解一下:
from collections import namedtuple
Name = namedtuple('Name', 'name age sex')
a = Name('王大錘', 18, '女')
b = Name('丑小鴨', 20, '鴨')
print(a.name, a.age, a.sex) # 結(jié)果: 王大錘 18 女
print(b.name, b.age, b.sex) # 結(jié)果: 丑小鴨 20 鴨
name = '王大錘'
sex = '男'
age = 18
print(f'{name}居然只有{age},{sex}?') # 結(jié)果王大錘居然只有18,男?
- 如何給字典排序,按鍵?按值?(貌似不新,不過挺有用)
my_dict = {'e': 4, 'b': 2, 'c': 1, 'd': 3}
a = sorted(my_dict)
b = sorted(my_dict.items())
c = sorted(my_dict.items(), key=lambda x: x[1])
print(a)
print(b)
print(c)
'''
