Answer 1

缩进块，更加小心！

def phone():
    import webbrowser
    print("Do you have an iphone or samsung?")
    answer = input ('iphone/samsung:')
    if answer == "iphone":
        print("what type of iphone?")
        answer = input ('5, 6 or 7:')
    if answer == "samsung":
        print("what type of samsung do you have?")
        answer = input ('s5, s6 or s7:')
x = input("press enter and type in your answer. phone(), tablet() or console() ")
if x == 'phone()':
    phone()
elif x == 'tablet()':
    tablet()
elif x == 'console()':
    console()

Answer 2

基本上，你拥有的是......

def foo():
    print("stuff")

answer = input("type foo()")

而answer == "foo()"是True。

你从未打电话给foo()，但你只是把它作为一个字符串输入。

你需要运行它。

exec(answer)

但是，exec非常糟糕，所以相反，您应该使用if和elif来调用相应的函数。

if answer == 'foo()': 
    foo()

在第一部电话（）之后为什么它不起作用？
