扫描字符串文字时出现 pandasql EOL 错误

pandasql EOL error while scanning string literal

我在下面的代码中尝试使用 pandasql 来 运行 sql 查询 sqldf。我正在做一些划分和聚合。当我使用 sqldf 在 r 中 运行 时,查询 运行 就很好了。我是 pandasql 的新手,我收到以下错误,任何人都可以看到我的问题是什么并建议如何解决它吗?我还包含了一些样本数据。

代码:

import pandasql
from pandasql import sqldf
pysqldf = lambda q: sqldf(q, globals())

ExampleDf=pysqldf("select sum(lastSaleAmount-priorSaleAmount)/sum(squareFootage) as AvgPric 
                              ,zipcode
                            from data
                            where priorSaleDate between '2010-01-01' and '2011-01-01'
                            group by zipcode
                            order by
                            sum(lastSaleAmount-priorSaleAmount)/sum(squareFootage) desc")

错误:
