为什么我的程序不读取其他变量？

Question

我是整个编程的新手，慢慢地在互联网上学习了一些东西，但我似乎无法找到解决方案或者只是不理解它。为什么程序不读取其他 elif 语句？这是我的第一个项目。我很感激任何提示和建议。欢迎任何建议和意见，谢谢！

#inputing
unknown = " "
while unknown != "exit":
    unknown = input("Please enter unknown: ").lower()
    angle = int(input("Please enter given angle: "))
#if base
    if unknown == "base" or "a":
        side = input("Height(b) or Hypotenuse(c)? ").lower()
        if side == "height" or "b":
            height = int(input("Please enter given height: "))
            base = int(height * tan(radians(angle)))
            print(">> The base is: " + str(base))
        else:
            hypotenuse = int(input("Please enter given hypotenuse: "))
            base = int(hypotenuse * cos(radians(angle)))
            print(">> The base is: " + str(base))

#if height
    elif unknown == "height" or "b":
        side = (input("Base(a) or Hypotenuse(c)?  ")).lower()
        if side == "base" or "a":
            base = int(input("Please enter given base: "))
            height = int(input(base * tan(radians(angle))))
            print(">> The height is: " + str(height))
        else:
            hypotenuse = int(input("Please enter given hypotenuse: "))
            height = int(hypotenuse * cos(radians(angle)))
            print(">> The height is: " + str(height))
    elif unknown == "exit":
        break
    else:
        print("I don't understand that..")

条件应为 if unknown == "base" or unknown == "a": 和 elif unknown == "height" or unknown == "b":。

在 unknown == "base" or "a" 中，第一个条件为 False unknown == "base" 并且 "a" 为 True，结果为 True "a".

#inputing
unknown = " "
while unknown != "exit":
    unknown = input("Please enter unknown: ").lower()
    angle = int(input("Please enter given angle: "))
#if base
    if unknown == "base" or unknown == "a":
        side = input("Height(b) or Hypotenuse(c)? ").lower()
        if side == "height" or "b":
            height = int(input("Please enter given height: "))
            base = int(height * tan(radians(angle)))
            print(">> The base is: " + str(base))
        else:
            hypotenuse = int(input("Please enter given hypotenuse: "))
            base = int(hypotenuse * cos(radians(angle)))
            print(">> The base is: " + str(base))

#if height
    elif unknown == "height" or unknown == "b":
        side = (input("Base(a) or Hypotenuse(c)?  ")).lower()
        if side == "base" or "a":
            base = int(input("Please enter given base: "))
            height = int(input(base * tan(radians(angle))))
            print(">> The height is: " + str(height))
        else:
            hypotenuse = int(input("Please enter given hypotenuse: "))
            height = int(hypotenuse * cos(radians(angle)))
            print(">> The height is: " + str(height))
    elif unknown == "exit":
        break
    else:
        print("I don't understand that..")
