파이썬을 사용하여 'id'입력을 기반으로 테이블에서 레코드를 검색하는 방법은 무엇입니까?

Question

나는 같은입니다 표 3을 가지고 내가 좋아하는 것입니다 표 2,

project_id |              energy_type              | uses |    target    |   title    
------------+-------------------------------------------------------------------------------------------------------------------------+------+----------------------------------+------------------------------ 
300  | {"Energy Not Entered","Assumed Mix Based on State & Property Type:","","Electric - Grid (56.9%)","Natural Gas (43.1%)"} |  | Target % Better than Median: 75 | About this Property's Design 
400  | {"Energy Not Entered","Assumed Mix Based on State & Property Type:","","Electric - Grid (56.9%)","Natural Gas (43.1%)"} |  | Target % Better than Median: 75 | About this Property's Design 

이 같은입니다 표,

project_id |     metric     | design_target | median_property | design_project 
------------+----------------------------------------+---------------+-----------------+---------------- 
300  | ENERGY STAR score (1-100)    | Not Available | 50    | Not Available

이

project_id | your_design_score 
------------+------------------- 
300  | N/A 
400  | N/A 

나는 테이블 기반 프로젝트에 참여하고있다. ct_id = '300'파이썬에서 #declared

PROJECT_ID 지금 PROJECT_ID 입력을 기반으로 레코드를 표시하려고

내가 같은 출력을 가지고, 파이썬 사용 코드 PROJECT_ID의 입력을 기반으로 위의 출력에서 ​​레코드를 표시해야합니다.

project_id가 PROJECT_ID와 일치하는 레코드를 표시해야합니다. execute 방법에 paremeter을 통과하는 SQL 측
