python - 我怎样才能使这个构造更简单，就像Python中的类或函数一样？

Question

print(
    "1. Engine block \n"
    "2. Pistons \n"
    "3. Crankshaft \n"
    "4. Camshaft \n"
    "5. Cylinder head \n"
    "6. Connecting Rod \n"
)

part = int(input("Choose an engine part to show you details about it: "))

if part == 1:
    print("Engine block")
elif part == 2:
    print("Pistons")
elif part == 3:
    print("Crankshaft")

我有 26 个这样的语句，我想知道是否可以通过类使其变得更简单，
函数、列表或其他我找不到方法的东西？？

Answer 1

我建议使用这样的东西:

def info_about(parts):
    info = list(parts.values())
    print("\n".join(f"{i+1}.\t\t{name}" for i, name in enumerate(parts)))

    print()
    while True:
        part = input("Choose an engine part to show you details about it: ")
        if not part.isnumeric():
            print("Please enter a valid number")
            continue

        part = int(part)
        if part > len(info) or part < 1:
            print("Please enter a valid number")
            continue
        break

    print(info[part-1])

parts = {
    "Engine block":         "Info about engine block",
    "Pistons":              "Info about pistons",
    "Crankshaft":           "Info about crankshaft",
    "Camshaft":             "Info about camshaft",
    "Cylinder head":        "Info about cylinder head",
    "Connecting Rod":       "Info about connecting rod",
}

info_about(parts)

现在检查输入以确保其有效 - 它是数字，并且介于 1 和零件数之间。
