    redrawGameWindow()

pygame.quit()

我正在MacOS上运行。我使用的是Python 2还是3，这有关系吗？任何帮助将不胜感激！

Answer 1

您忘记在上一行290处加上一个括号。

这种语法错误与Python版本或操作系统无关。

您可以使用IDE（例如PyCharm，EMACS）或静态分析器（例如pycheck）轻松发现它。

Answer 2

这是丢失的')'

请先检查以下行：

print(': Starting Active Trader with preferred stock {}...'.format([preferredStock[0]])
stock_list.remove(preferredStock[0])

缺少用于打印的右括号。

我无法确定为什么引发此SyntaxError
