I have list of dictionaries with nested structure. I need to remove all duplicate values. I'm newbie in Python and can't solve this task. Anyone can help me?
My list looks like:
[
{
"task_id":123,
"results":[
{
"url":"site.com",
"date":"04.18.2019"
},
{
"url":"another_site.com",
"date":"04.18.2019"
},
{
"url":"site1.com",
"date":"04.18.2019"
}
]
},
{
"task_id":456,
"results":[
{
"url":"site3.com",
"date":"04.18.2019"
},
{
"url":"site.com",
"date":"04.18.2019"
}
]
},
{
"task_id":789,
"results":[
{
"url":"site7.com",
"date":"04.18.2019"
},
{
"url":"site9.com",
"date":"04.18.2019"
},
{
"url":"site.com",
"date":"04.18.2019"
}
]
}
]
I need to set site.com only once. If any value of url is duplicated - exclude it from dict.
As result: task 123 with 3 dicts in results task 456 with 1 dict in results (exclude site.com) task 789 with 2 dict in results (exclude site.com)
Desired output should looks like:
[
{
"task_id":123,
"results":[
{
"url":"site.com",
"date":"04.18.2019"
},
{
"url":"another_site.com",
"date":"04.18.2019"
},
{
"url":"site1.com",
"date":"04.18.2019"
}
]
},
{
"task_id":456,
"results":[
{
"url":"site3.com",
"date":"04.18.2019"
}
]
},
{
"task_id":789,
"results":[
{
"url":"site7.com",
"date":"04.18.2019"
},
{
"url":"site9.com",
"date":"04.18.2019"
}
]
}
]
let results to be your array.
u = set()
final = []
for dict in results:
for res in dict["results"]:
if res["url"] not in u:
u.add(res["url"])
final.append(res)
print(final)
