输入为整数

Question

我正在玩Python3。我希望weight成为一个int，但我不知道我做错了什么。

age = input("How old are you? ")
height = input("How tall are you? ")
#Since I want to play around, I just want to Turn KG to LBS
#Below is where I'm stuck
weight = int(round(input("How much do you weight? ")*2.2046))

print(f"so you are {age} old, {height} tall and {weight}LBS heavy")

提前致谢。

Answer 1

您必须首先将输入（string）转换为int / float，然后才能对其进行数字操作（*）。< / p>

即

weight = round(int(input("How much do you weight? "))*2.2046)

注意首先评估int(input('...weight?'))，然后评估*2.2046部分，最后评估round()。
