我正在尝试编写一个程序，通过询问一个人的体重（千克）和身高（米）来计算体重指数。为什么我在这里得到无效的语法错误？
units = input("What units would you like to use? Enter I for Imperial or M for Metric")
weight = input(int("what's your weight?")
height = input(int("what's your height?")

你选错了订单。您应该 submitData()
{
var anyChangeDetected: boolean = false;
for(var i=0;i<this.subscriptionList.length;i++)
{
if(this.subscriptionList[i].value != this.subscriptionList[i].initialValue)
{
anyChangeDetected = true;
this.remedyService.submitSubscription(this.subscribeObject).subscribe(
data =>{
},
err=>{
},
()=>{
});
}
}
if(anyChangeDetected == false)
{
alert("Data is not changed");
}
}
而不是int(input())
而且你的input(int())比你应该少。{1}}。检查每个开口支架是否有关闭

您的int和输入顺序错误，并且忘记了右括号：
units = input("What units would you like to use? Enter I for Imperial or M
for Metric")
weight = int(input("what's your weight?"))
height = int(input("what's your height?"))

避免使用input（）并使用raw_input（）代替。你也把int（）放在错误的地方。
您的代码应如下所示：
units = raw_input('What units would you like to use?....')
weight = int(raw_input("what's your weight?"))
height = int(raw_input("what's your height?"))
