Python string and array not working properly

Question

From conditionId input field i am getting comma separated string eg 'Test1','Test2','Test3' below is the code for that i want to split that string and access individual value using for loop

ConditionId =str(request.POST.getlist("ConditionId"))
ConditionIdArray = [n for n in ConditionId[1:-1].split(',')]

for i in range(0,len(ConditionIdArray)):
    print(ConditionIdArray[i])

In print statement it giving me output as

'Test1'
'Test2'
'Test3'

but i want output as

Test1
Test2
Test3

Because when i am storing data in database it stored as 'Test1' not as normal Test1

POST.getlist will return a list of strings. Don't convert it string and split, just iterate it (no need to use range and indexing):

condition_ids = request.POST.getlist("ConditionId")

for condition_id in condition_ids:
    print(condition_id)

A little explanatory addition to @falsetru's answer. The str() of a list uses repr() for displaying its elements, thus for [x, y, z] it is:

[repr(x), repr(y), repr(z)]

and not, as one might expect

[str(x), str(y), str(z)]

And for strings, that makes a difference:

> s = 'Test1'
> print(str(s))
Test1

> print(repr(s))
'Test1'  # so, splitting the str(list) on commas leaves the quotes
