Getting values from a dictionary - brunolelli - Mar-31-2021

Hello guys,

I'm using the following API project in order to collect some data from Flight Radar 24.
https://pypi.org/project/FlightRadarAPI/

In the project's documentation it's written that:
You can also get more information about a specific flight such as: aircraft images, estimated time, trail, etc.

details = fr_api.get_flight_details(flight.id)
flight.set_flight_details(details)
print("Flying to", flight.destination_airport_name)
So, in order to get the value of some 'fields' I'm using the following expression:
print(details['time']['real']['departure'])
print(details['time']['real']['arrival'])

print(details['time']['estimated']['departure'])
print(details['time']['estimated']['arrival'])
My question is:
Is there any better and more 'inteligent' way of doing this?

Basically my intention is to loop through all flights of some airlines...

Depends on the structure of the data. This does look pretty clear, what are you looking for?

RE: Getting values from a dictionary - deanhystad - Mar-31-2021

Are you just trying to print information? You can print the dictionary or sub-dictionaries like this:
print('Real time', details['time']['real'])

If you don't like how that looks you could try the pretty print library.

I would like to add it in my code and export the information to a TXT file.

this is the code i'm currenty running
import csv
import time
import sched, time
from datetime import datetime
from FlightRadar24.api import FlightRadar24API

fr_api = FlightRadar24API()
empresas = ['JES', 'DAP', 'GLO', 'THT', 'BWA']

while True:
    try:
        now = datetime.now()
        day = datetime.today()
        current_time = now.strftime("%H:%M")
        current_day = day.strftime("%d/%m/%y")
        
        for i in range(0,len(empresas)):
            flights = fr_api.get_flights(airline = empresas[i])
            #print(type(flights[0]))
            #print(flights[0].__dict__)

            print("Dados da empresa: ", empresas[i], " atualizado as: ", current_time)

            with open(r'C:\Users\bruno\Desktop\Voos\DB\Voos.txt', 'a', newline='') as f:
                fieldnames = ['dia_analisado',
                              'hora_analisada',
                              'data',
                              'hora',

                              'squawk'                              
                              ] # you can include whatever attributes you want
                wrtr = csv.DictWriter(f, fieldnames=fieldnames, extrasaction='ignore', delimiter=';')
                #wrtr.writeheader()
                for flight in flights:

                    flight.hora_analisada = current_time
                    flight.dia_analisado = current_day
                    wrtr.writerow(flight.__dict__) # here I pass all attributes as dict, but you can always access individual attributes, like I did with time above
        time.sleep(60)  
    except:
        print('Olha deu erro, mas vou tentar novamente!')
        time.sleep(10)

I would like to add it in my code and export the whole information to a TXT file.
How can I incorporate this new set of code to my project?

It can be easier if take data first into Pandas,then get out all kind of formats.
A example and for plain text can use df.to_string.
import requests
import pandas as pd

# Api
url = 'https://min-api.cryptocompare.com/data/histoday?fsym=BTC&tsym=ETH&limit=5&aggregate=1&e=CCCAGG'
data = requests.get(url).json()['Data']

# To Pandas
df = pd.DataFrame.from_dict(data)

# To txt
with open('out.txt', 'w') as f:
    f.write(df.to_string(index=False))
Output:
