第一题
def normalize(name): return name[0].upper() + name[1:].lower()
L1 = ['aDam', 'LiSSa', 'barT'] L2 = list(map(normalize, L1)) print(L2)
第二题
from functools import reduce
def mul(x, y): return sum([x, y])
def prod(L): return reduce(mul, L)
print(prod([1,3,5,7,9]))
第三题
def str2float(s): s = s.split('.') def f1(x, y): return x * 10 + y def f2(x,y): return x / 10 + y def str2num(str): L = { '0': 0, '1': 1, '2': 2, '3': 3, '4': 4, '5': 5, '6': 6, '7': 7, '8': 8, '9': 9 } return L[str] return reduce(f1, map(str2num, s[0])) + reduce(f2, list(map(str2num, s[1]))[::-1]) / 10
print(str2float('123.456'))
