我一直在学习python 3.5，并试图得到一个字符串来转载一个用户输入的变量？

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：% 的操作数类型不受支持：'NoneType' 和 'str

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))

Answer 2

有点像菜鸟。实现此目的的一种简单方法是在分配变量

时询问您的问题

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

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

Answer 3

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))

如果将变量放在引号中，它就会变成一个字符串。如果要添加另一个变量，还要确保每个变量后面都有一个逗号。
