在sp上出现语法错误

Question

我真的不知道为什么会这样，有人能帮我解释一下为什么会出现语法错误吗

Menu_select = input("""
[------------------]
[    Menu.model    ]
[ 1) Start:        ]
[ 2) Options:      ]
[ 3) Placeholder1: ]
[ 4) Placeholder2: ]
[ 5) Exit:         ]
[------------------]
"""))
if Menu_select == '1':
    startyn = input('Do you want to start? ')
    while startyn != 'Yes' or startyn != 'yes' or startyn != 'y' or startyn != 'Y':
        if startyn == 'Yes' or startyn == 'yes' or startyn == 'y' or startyn == 'Y':
            print('Okay lets start!')
        elif startyn == 'No' or startyn == 'no' or startyn == 'N' or startyn == 'n':
            print('Okay back to the menu!')
elif Menu_select == '2':
    optionsyn = input('Do you want to go into the options? ')
