i have a problem;
import requests
import json
from datetime import datetime
result = requests.get("https://api.exchangeratesapi.io/history?start_at=2020-12-1&end_at=2020-12-13&symbols=USD,TRY&base=USD")
result = json.loads(result.text)
print(result["rates"])
print(sorted(i, key=lambda date: datetime.strptime(date, "%Y-%m-%d")))
And i added the error in the below. I want to sort the dates.
The variable i
has no meaning here, you can do
ra = result["rates"]
ra = sorted(ra, key=lambda date: datetime.strptime(date, "%Y-%m-%d"))
print(ra)
This will return a list because dict has no order in Python(always,). you can not put any order on dict elements.
To use a ordered dict, you can try OrderedDict
in Python, see
https://docs.python.org/3/library/collections.html#collections.OrderedDict
I think the missing variable i
is result
? If that's the case, you can do something like this:
sorted_rates = dict(sorted(
result["rates"].items(),
key=lambda item: datetime.strptime(item[0], "%Y-%m-%d")))
Here, we first convert the dictionary result["rates"]
into an array of tuples of the form (key, value)
. Then we sort that using a comparator function that gets the string date from the tuple by accessing the first element ( item[0]
).
