【问题描述】：

我正在尝试通过将 A.csv 中的 districtname 列与国家 CSV 数据库 B.csv 进行关联来更正它

这是我A.csv的内容

"Series","No","districtname","PinCode"
"A","101","Mysuru","570010"
"A","103","D. K. ","574216"
"A","104","Bengaluru","560004"
"A","105","Bengaluru","560010"
"A","106","Doddaballapura","561203"
"A","107","Bengaluru","560002"
"A","109","Bengaluru","560050"
"A","110","Bengaluru","560076"
"A","111","Tumkur ","572112"

B.csv的内容

PinCode,districtname
744112,South Andaman
744101,South Andaman
744103,South Andaman
744104,South Andaman
744201,North And Middle Andaman
744107,South Andaman
744302,Nicobar
744301,Nicobar
744202,North And Middle Andaman
...……

如何使用A.csv 中的PinCode 列作为查找B.csv 中提到的官方地区名称的关键

csvkit 命令行方法会很有帮助。
