我已经写了一下午了，还是没有任何想法

给我一些思路，或者实例，那个感觉无从下手，无论是def还是其他的都可以，谢谢

import random

a = [str(random.uniform(-200, 200)) + "\n" for i in range(15)]

with open("temps_input.txt", "w") as f:
    f.writelines(a)


def covert_temps(F):
    C = (F - 32) / 1.8
    return C


with open("temps_input.txt", "r") as f:
    F = f.readlines()
    C = [str(covert_temps(float(i[:-2]))) + "\n" for i in a]

with open("temps_output.txt", "w") as f:
    f.writelines(C)
