所以我的代码在下面
import requests
import json
with open("forex_rates.json", "r") as file:
rate = json.load(file)
nrate = rate
Base = input("enter your base currency: ")
if Base not in rate["rates"]:
print("That's not a valid currency...")
Base = input("enter your base currency: ")
with open("forex_rates.json", "r") as file:
nrate["base"] = Base
for i in rate["rates"]:
nrate["rates"][i] = rate["rates"].get(i) / rate["rates"].get(Base)
print(nrate["rates"])
我正在尝试制作一个可以转换不同货币的程序，例如： 1欧元-> 1.18美元 为了做到这一点，我必须根据基准值每次编辑外汇汇率 当我完成代码后，我运行了它，一切正常，它转换了所有值，直到在外汇价值文件中达到相同的值 就像如果我从USD转换，它将根据USD更改所有货币值，但是当文件中的USD达到USD时，循环中断 我尝试了很长时间，直到尝试将USD移到文件的最底部为止，因为它没有损坏的余地。确实有效，但这仅适用于美元。 当我在程序中更改基本值时，它将再次中断
对于那些说代码甚至还没有完成的人，我会说我几乎将程序的这一部分完成了转换部分，我认为最困难的部分，剩下的任何其他代码只是GUI和一些乘法运算
，我将在下面列出外汇数据 ＃对不起，如果太大的话
