扫描字符串文字时，pandasql EOL错误
[英]pandasql EOL error while scanning string literal
问题描述
我在下面的代码中尝试使用pandasql使用sqldf运行sql查询。 我正在做一些划分和汇总。 当我使用sqldf在r中运行查询时，查询运行良好。 我是pandasql的新手，并且出现以下错误，任何人都可以看到我的问题并提出解决方法的建议吗？ 我还提供了一些示例数据。
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：
File "<ipython-input-100-679165684772>", line 1
ExampleDf=pysqldf("select sum(lastSaleAmount-priorSaleAmount)/sum(squareFootage) as AvgPric
^
SyntaxError: EOL while scanning string literal

只需更改引号即可读取多行字符串：
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""")
