Question

我正在处理作业问题，并收到以下错误：

Traceback (most recent call last):

File "/Users//Dropbox/Homework 3 - 2.py", line 15, in <module>
    conversion = convert_feet_to_inches(get_feet)   
File "/Users//Dropbox/Homework 3 - 2.py", line 4, in convert_feet_to_inches
    calculate_conversion = feet*12 TypeError: 
unsupported operand type(s) for *: 'function' and 'int'

这是我的代码。我正试图将脚转换成英寸：

def convert_feet_to_inches(feet):
    calculate_conversion = feet*12
    return calculate_conversion

def get_feet():
    ask_for_feet = float(input("Please enter number of feet for conversion "))
    return ask_for_feet

def printing_answer():
    print (convert_feet_to_inches)

asking_for_feet = get_feet()
conversion = convert_feet_to_inches(get_feet)
print_answer(printing_answer)

我做错了什么？

Answer 1

我认为您打算将asking_for_feet传递给convert_feet_to_inches而不是此行中的get_feet函数：

conversion = convert_feet_to_inches(get_feet)

那应该是：

conversion = convert_feet_to_inches(asking_for_feet)

Answer 2

错误是因为get_feet()是一个函数，你将它传递给convert_feet_to_inches()，它将你传递的参数传递给它并将它乘以12.你不能将函数乘以int所以这就是错误所说的。我认为你打算做的是通过asking_for_feet。所以改变

conversion = convert_feet_to_inches(get_feet)

到

conversion = convert_feet_to_inches(asking_for_feet)

之后，你有

print_answer(printing_answer)

函数print_answer尚未定义，因此更改：

def printing_answer():
    print (convert_feet_to_inches)

到

def print_answer(answer):
    print (answer)

然后你最后一行代码是：

print_answer(conversion)
