未使用打印功能定义python变量

Question

运行以下代码后，python提示错误，并告诉我未定义名称“ tony”。

print('Hello Sam, this is Javis')
#let user enter their name, "nm" being the variable
nm = input('Please tell me your name => ')
print('It is definitely nice to meet you',nm,'!')

我输入的名字是“ Tony”

我做错了什么？

Answer 1

由于要添加输入，因此需要使用“ +”而不是逗号。像这样：

print('It is definitely nice to meet you '+nm+'!')
