python - 我一直在学习python 3.5，并试图获取一个字符串来转载用户输入的变量？

Question

print ("how old are you??"),
age = input()
print("How tall are you"),
height = input()
print("How much do you weigh"),
weight = input()

print("So, you're '%r' old, '%r' tall and weigh '%r' ") % ('age, height weight')

TypeError: %: 'NoneType' 和 'str 不支持的操作数类型

Answer 1

不要将变量放在引号中。而不是

print("So, you're '%r' old, '%r' tall and weigh '%r' ") % ('age, height weight')

放

print("So, you're '%r' old, '%r' tall and weigh '%r' " % (age, height weight))
