Python에서 잘못된 순서로 연결하고 문자열의 일부를 덮어 씁니다.

Python 스크립트에서 이상한 출력이 나타납니다.

Paramiko와 관련된 실제 실행을 위해 루프에서 코드를 실행할 때 출력 시작 부분을 덮어 쓰면서 인쇄 할 변수의 순서를 반대로하는 것처럼 보입니다.

처리 할 모든 소스 텍스트는 둘 다 동일합니다. 하나는 라우터에서 ssh를 통해 Paramiko를 통해 가져오고 다른 하나는 수동으로 가져 와서 로컬 변수로 붙여 넣었습니다.

전류 출력 :

with testis 10.8.11.72 from 10.8.11.72 (10.111.72.1)

정적 로컬 변수가있는 원하는 출력 및 출력 :

Best Path is 10.8.11.73 from 10.8.11.73 (10.111.73.1) with localpref 120

나는 이것이 왜 일어나고 있는지 세상적인 아이디어가 없습니다. 자세한 정보 및 실행은 아래를 참조하십시오. 도움?
