python for loop removing duplicated output data in list - python-3.x

Question

from a python for loop i get duplicated output data for each iteration.
what i want is to only get the new data in each iteration.
How can i remove the repeated data from the list and only get the not repeated data
the data that gets dublicated is the hours minutes and seconds
sorry for my english .
import json
with open('activities.json') as f:
d = json.load(f)
keys = []
values = []
lijst = [[],[]]
def loop():
for y in d['activities']:
name = y['name']
lijst[0].append(name)
p = y['time_entries']
for e in p:
h = e['hours']
m = e['minutes']
s = e['seconds']
lijst[1].append(h)
lijst[1].append(m)
lijst[1].append(s)
print(lijst[1])
test = dict((k, lijst[1]) for k in [name])
loop()
output the first data is repeated in the second list the second is repeated in the third and so on:
[1, 2, 11, 0, 0, 1, 0, 0, 4, 0, 0, 2, 0, 0, 1, 0, 0, 13, 0, 0, 1]
[1, 2, 11, 0, 0, 1, 0, 0, 4, 0, 0, 2, 0, 0, 1, 0, 0, 13, 0, 0, 1, 0, 0, 6, 0, 0, 12, 0, 0, 10, 0, 0, 3]
[1, 2, 11, 0, 0, 1, 0, 0, 4, 0, 0, 2, 0, 0, 1, 0, 0, 13, 0, 0, 1, 0, 0, 6, 0, 0, 12, 0, 0, 10, 0, 0, 3, 0, 0, 5, 0, 0, 1, 0, 0, 2, 0, 0, 4, 0, 0, 1, 0, 0, 3, 0, 0, 8, 0, 0, 5, 0, 0, 9, 0, 0, 14]

Answer 1

Just reset lijst at the begging of each iteration:
import json
with open('activities.json') as f:
d = json.load(f)
keys = []
values = []
def loop():
for y in d['activities']:
lijst = [[],[]] #reset list
name = y['name']
lijst[0].append(name)
p = y['time_entries']
for e in p:
h = e['hours']
m = e['minutes']
s = e['seconds']
lijst[1].append(h)
lijst[1].append(m)
lijst[1].append(s)
print(lijst[1])
test = dict((k, lijst[1]) for k in [name])
loop()
