1. lambda x: x * i 与 lambda x, i=i: x * i 的区别
def multipliers(): # 添加了一个默认参数i=i return [lambda x: i * x for i in range(4)] print([m(2) for m in multipliers()]) # [6, 6, 6, 6]
def multipliers(): # 添加了一个默认参数i=i return [lambda x, i=i: i * x for i in range(4)] print([m(2) for m in multipliers()]) # [0, 2, 4, 6]
