functools.partial创建字典时,我将使用此参数来指定参数:
from functools import partialoptions = {0: FunctionZero, 1: FunctionOne, 2: FunctionTwo,3: partial(FunctionThree, True)}
请注意,这还允许在调用函数时传递其他参数(只要字典中的所有函数在
partial调用后都缺少相同的参数):
def test(one, two, three=None, four=None): ...def test2(one, two, three=None): ...options = {1: partial(test, 1, three=3, four=4),2: partial(test2, 1, three=3)}...options[choice](2) # pass the 'two' argument both functions still require
