Python BMI计算器我无法弄清楚这个问题。

Question

所以当我运行程序时出现此错误，我不知道为什么这不起作用。

C：\ Python27＆gt; python bmi.py   文件“bmi.py”，第11行     def getweight（wt）                     ^ SyntaxError：语法无效

print('BMI Calculator!')
#declaring my variables
ht=height
wt=weight
bm=bmi
#Calling my main function
main()

#getting user input for weight in pounds
def getweight(wt)
    weight = int(input('Please enter your weight input pounds(whole number):    '))
return(wt)

#getting user input for height in inches
def getheight(ht)
    height = int(input('Please enter your height input in inches(whole number): '))  
return(ht)

#function for the bmi calculator 
def bmicalc()
    bmi = (wt*703)/(ht*ht)

#main function  
def main()
getweight()
getheight()
bmicalc()

您需要在函数声明的末尾添加冒号。像这样：

def foo(bar):
    pass
