我想你想要这样的东西:

int_list = [2, 33, 4, 55, 5, 56, 34, 6, 6, 76, 78657, 234, 3, 4]
New = []

for N in int_list:
    New.append(str(N) + ('small' if N < 30 else 'large'))
print(New)

结果:

['2small', '33large', '4small', '55large', '5small', '56large', '34large', '6small', '6small', '76large', '78657large', '234large', '3small', '4small']

你可以用 eval

d2 = {key: eval(str(value)) for key, value in d1.items()}

{
    ('a', 'b'): 300.0,
    ('b', 'c'): 0.21000000000000002,
    ('a', 'c'): 0.462,
    ('c', 'e'): 0.68,
    ('b', 'a'): 0.21000000000000002,
    ('c', 'd'): 4.2
}
