python API calls json response - lowest value-CodePudding

I'm doing an API call and getting the below output. But what I'm actually looking for is only the lowest value for 'Active Tunnels' to be displayed. I know "for" loop is the answer but I've tried so many things in the past 5 hours and got no where close to my goal. Please help me.

{u'histdata': [{u'Active Tunnels': 378.0, u'Utilization': 2.0, u'coverage': u'100 %', u'datetime': u'22/11/2021 16:00:49'}, {u'Active Tunnels': 377.0, u'Utilization': 2.0, u'coverage': u'100 %', u'datetime': u'22/11/2021 16:01:49'}, {u'Active Tunnels': 376.0, u'Utilization': 2.0, u'coverage': u'100 %', u'datetime': u'22/11/2021 16:02:49'}, {u'Active Tunnels': 374.0, u'Utilization': 2.0, u'coverage': u'100 %', u'datetime': u'22/11/2021 16:03:49'}]

You can try this, FYI it's not the optimal solution but i think it will solve the issue , u is for Unicode This will give you the dict having lowest value for Active Tunnels, you can easily get the value for that key

d = {u'histdata': [{u'Active Tunnels': 378.0, u'Utilization': 2.0, u'coverage': u'100 %', u'datetime': u'22/11/2021 16:00:49'}, {u'Active Tunnels': 377.0, u'Utilization': 2.0, u'coverage': u'100 %', u'datetime': u'22/11/2021 16:01:49'}, {u'Active Tunnels': 376.0, u'Utilization': 2.0, u'coverage': u'100 %', u'datetime': u'22/11/2021 16:02:49'}, {u'Active Tunnels': 374.0, u'Utilization': 2.0, u'coverage': u'100 %', u'datetime': u'22/11/2021 16:03:49'}]}

lowest = []
for line in d.get('histdata'):
    low = float(line.get('Active Tunnels'))
    if len(lowest) == 0:
        lowest = [line]
    else:
        if lowest[0].get('Active Tunnels')  > low:
            lowest = [line]
        else:
            pass

print(lowest)
# use this for lowest value
# print(lowest[0].get('Active Tunnels'))

[{'Active Tunnels': 374.0, 'Utilization': 2.0, 'coverage': '100 %', 'datetime': '22/11/2021 16:03:49'}]

And you are missing } at end in your data

In the meantime, I was able to isolate only the values for 'Active Tunnels' and print them in integer format. I'm just one step close now i.e. get the lowest value

data=r.json()
print(data['histdata'])
for vpn in data['histdata']:
    tunnel = int(vpn['Active Tunnels'])
    print(tunnel)
