uniqueid='xyz1235'

list1=[1,2,3,4]
list2=['a','b','c','d']

Desire output should be :- [('xyz1235',1, 'a'), ('xyz1235',2, 'b'), ('xyz1235',3, 'c'), ('xyz1235',4, 'd')]

With the help of Zip i am able to do with list1 and list2 but not able to add uniqueid string in this way. Can you please help.

CodePudding user response：

There are various ways to achieve this.

One of them would be to use list comprehension to explicitly construct desired list:

out = [(uniqueid, item[0], item[1]) for item in zip(list1, list2)]

Another way is to forcefully build a list0 variable that you can then zip along with others, as in:

list0 = [uniqueid] * len(list1)
out = zip(list0, list1, list2)

Probably from there you can imagine your own creative ways of doing equivalent work.
