权重 python 错误 SyntaxError

Question

我又在复习了Python，又到了这个早期阶段，又卡住了。我需要：

Write a program in Python that will ask for the user's
Name and 'weight' in kilograms. The program will then
Output a sentence informing the user of their weight in grams and in pounds.

这是我的代码：

myName = str(input('What is your name?:'))

myWeight = int(input( myName+ 'What is your weight in kilograms?:')

weightGrams = 'myWeight*1000'
weightPounds = 'myWeight*2.2'



print(myName+ 'You would weigh', weightGrams, 'in grams and' weightPounds, 'in pounds!')

我没有得到正确的输出，而且我得到了语法错误。语法错误在这里：

weightGrams = 'myWeight*1000'
weightPounds = 'myWeight*2.2'

最后：

print(myName+ 'You would weigh', weightGrams, 'in grams and' weightPounds, 'in pounds!')

我该如何解决这些问题？

Answer 1

不要将 int 视为 string:

weightGrams = myWeight*1000
weightPounds = myWeight*2.2

你的 print:

中也有语法错误

print(myName+ ' You would weigh', weightGrams, 'in grams and', weightPounds, 'in pounds!')

此外，您不需要在此处强制转换为 str，因为 input 已经给出 string:

myName = input('What is your name?:')

最终编辑：您在此处缺少右括号 )：

myWeight = int(input( myName+ 'What is your weight in kilograms?:'))
