python - Merge multiple lists into a dictionary

Question

I have simplified the original question and hope you can help me a lot

There are 2 lists of equal length:
idlist = [id1,id2,id3,id4,id5]
userlist = [name1,name2,name3,name4,name5]

Hope to merge into a dictionary in the following form:

dict_user = {{'id':id1, 'name':name1},{'id':id2, 'name':name2},{'id':id3, 'name':name3},{' id':id4, 'name':name4},{'id':id5, 'name':name5}}

How to generate the above dictionary?

Supplement: python 3

Answer 1

First of all, your dict_user does not look like a dictionary, but each element in it is a dictionary. You can use the zip function to merge two lists of equal length into a two-dimensional list. In python3, idlist = [id1, id2, id3, id4, id5]
userlist = [name1,name2,name3,name4,name5]
zipped= zip(idlist, userlist)
user= [dict(id=id,name=name) for id ,name in list(zipped)]
You can get
user = [{'id':id1, 'name':name1},{'id':id2, 'name':name2},{'id':id3, 'name':name3},{' id':id4, 'name':name4},{'id':id5, 'name':name5}]

Answer 2

for way

var listObj={},dict_user=[];
for(var i=0,len=idlist.length;i<len;i++){
    listObj.id=idlist[i]
    listObj.name=userlist[i]
    dict_user.push(listObj);
}

foeEach

var listObj={},dict_user=[];
idlist.forEach(function(item,index,self){
    listObj.id=item;//listObj.id=idlist[index];
    listObj.name=userlist[index];
    dict_user.push(listObj);
})



忽略吧！我看错了！

Answer 3

First of all
dict_user = { ... } This form should be a set (set/frozenset), but both of them require the stored object to be hashable, that is, it cannot be a variable object like dict, so there is no such thing form.

Answer 4

should bedict_user = [{'id':id1, 'name':name1},{'id':id2, 'name':name2},{'id':id3, 'name':name3},{ 'id':id4, 'name':name4},{'id':id5, 'name':name5}]Well, if so, the code is as follows:

dict_user = [{"id": id, "name": user} for id, user in zip(idlist, userlist)]
