Question

我正在编写一个python游戏，我一直在犯错误

define_direction( DOWN, "down" )
ParseError: bad input

SyntaxError：语法无效（＆lt; string＆gt;，第115行）

我正在使用http://www.pythontutor.com/visualize.html

原始基本代码：http://blog.trinket.io/python-text-adventure/

我不明白当其他所有工作时它是如何无效的语法。我该如何解决这个错误。任何机构都有关于如何处理文本冒险游戏中的移动和方向的任何建议。

修正了谢谢wim !!

解＆＃34;你错过了前一行的右括号：

define_direction（UP，＆＃34;以上＆＃34; 当python抱怨语法错误时，通常会在它实际抱怨的行之前查看该行。＆＃34;

Answer 1

您错过了上一行的右括号：

define_direction( UP, "above"

当python抱怨语法错误时，通常会在它实际抱怨的行之前查看该行。

Python 3.5语法错误，ParseError：输入错误
