Creating A List Of Dictionaries With Same Keys?
Solution 1:
When you append the dictionary person to the list people you are just appending a reference to the dictionary to the list, so the list ends up containing just references to the SAME dictionary.
Since each time through the loop you overwrite the dictionary with new values, at the end the list contains just references to the last person you appended.
What you need to do is create a new dictionary for every person, for example:
for human in humans:
number_people, people_data = People.data()
person = dict()
person['name'] = human.name
person['age'] = human.age
person['Sex'] = human.name
people.append(person)
Solution 2:
You each time edit the same dictionary, so you do not construct a new one, but edit the old one. Since you each time append the same dictionary to the list, in the end the list contains the same dictionary n times, and all edits are processed on that dictionary.
You thus have to construct a new dictionary in each iteration in the for
loop:
people = []
humans = gethumans()
for human in humans:
number_people, people_data = People.data()
person = {
'name': human.name,
'age': human.age,
'sex': human.sex
}
people.append(person)
I here replaced 'Sex'
with 'sex'
(since it is strange to have inconsistent key names), and used human.sex
instead of human.name
.
Here people.data()
do not seem to do anything, you can thus use list comprehension here to generate the list:
people = [
{ 'name': human.name, 'age': human.age, 'sex': human.sex }
for human in humans
]
This will construct a list with all the dictionaries. Given the for
loop had no side-effects (this looks to be the case), the above will work.
