小白，请教各位大佬！python list转换成指定条件的dict，如下，求指导！

Question

python中有一个list是[A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q],需要组成的dict数据结构如下:{A:[B,C],B:[D,E],C:[F,G],D:[H,I],E:[J,K],F:[L,M],G:[N,O],H:[P,Q],I:[],J:[],K:[],L:[],M:[],N:[],O:[],P:[],Q:[],}十分感谢!

Answer 1

l=['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q']d={l[i]:[l[j]forjinrange(2*i+1,2*i+3)ifj

Answer 2

合理使用列表切片与字典推导。s=['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q']d={s[i]:s[i*2+1:i*2+3]foriinrange(len(s))}
