Compare multiple value in a dictionary and get bigger value key-CodePudding

How can I compare that 2 keys with the highest length of the value? I wanna found the highest key name which has a bigger length.

{
'UFTBUSD': ['Hammer', 'Belthold', 'Doji', 'Three Outside', 'Hanging Man', 'Closing Marubozu', 'Dragonfly Doji', 'Engulfing Pattern', 'Gravestone Doji', 'Harami Pattern'], 
'ANCBUSD': ['Belthold', 'Doji', 'Three Outside', 'Shooting Star', 'Closing Marubozu', 'Engulfing Pattern', 'Harami Pattern']
}

    'ANCBUSD': ['Belthold', 'Doji', 'Three Outside', 'Shooting Star', 'Closing Marubozu', 'Engulfing Pattern', 'Harami Pattern']
    }

      for value in y:
        if len(value) > count_value:
            count_value  = len(value)
            print(len(value))
            longest_value = value
            longest_values_key = x
    print(longest_value)
    print(longest_values_key)
    return longest_values_key
    
    
find_longest_key(thisdict)
