Add list within list while creating a new 'label'

April 7, 2022

I have 2 lists; or at least, I believe they are lists:

one = [{'sex': 'M', 'age': 22},
      {'sex': 'M', 'age': 76},
      {'sex': 'F', 'age': 37},
      {'sex': 'F', 'age': 45}]

two = [0, 1, 0, 0]

I want to append the list two to the list one while creating a new ‘label’.

The desired output should look like this (and still be a list):

[{'sex': 'M', 'age': 22, 'new label': 0},
 {'sex': 'M', 'age': 76, 'new label': 1},
 {'sex': 'F', 'age': 37, 'new label': 0},
 {'sex': 'F', 'age': 45, 'new label': 0}]

This must be easy but I can’t make it work and couldn’t use closely related answers on so. Using just .append(two) put list two at the end of list one of course, instead of inserting it within list one.

Feel free to flag as duplicate if needed, but please help with this particular example! Many thanks

>Solution :

for d, v in zip(one, two):
    d["new_label"] = v

one
# [{'sex': 'M', 'age': 22, 'new_label': 0},
#  {'sex': 'M', 'age': 76, 'new_label': 1},
#  {'sex': 'F', 'age': 37, 'new_label': 0},
#  {'sex': 'F', 'age': 45, 'new_label': 0}]
