Python invalid syntax on a string?
提问by A.J.
I am very new to coding so I hope my question makes sense/is formatted correctly.
我对编码很陌生，所以我希望我的问题有意义/格式正确。
Here is my code:
这是我的代码：
#this function takes a name and a town, and returns it as the following:
#"Hello. My name is [name]. I love the weather in [town name]."
def introduction("name","town"):
phrase1='Hello. My name is '
phrase2='I love the weather in '
return ("phrase1" + "name" + "phrase2" + "town")
E.g. introduction("George","Washington")in the python shell would return as "Hello. My name is George. I love the weather in Washington."
例如introduction("George","Washington")在 python shell 中将返回为"Hello. My name is George. I love the weather in Washington."
My problem is that my code is not doing that. Instead I get the following error:
我的问题是我的代码没有这样做。相反，我收到以下错误：
Invalid syntax: <string> on line 1". In Wing101 **,"town"):
has a red swiggle under it. I'm not sure what I did wrong...I know "name" and "town" are strings and not variables, but I really have no idea how to fix it.
在它下面有一个红色的摆动。我不确定我做错了什么......我知道“name”和“town”是字符串而不是变量，但我真的不知道如何解决它。
Any help/comments are appreciated.
任何帮助/评论表示赞赏。

You can't use string literals as function arguments, no. You can only use variable names. Remove all the double quotes:
您不能使用字符串文字作为函数参数，不。您只能使用变量名。删除所有双引号：
def introduction(name, town):
phrase1='Hello. My name is '
phrase2='. I love the weather in '
return (phrase1 + name + phrase2 + town)
You pass in strings when calling the function:
调用函数时传入字符串：
introduction("George", "Washington")
and these then get assigned to nameand townrespectively.
然后这些分别分配给name和town。
