Questo è il mio codice

import csv 
import json 

output = {} 
country = { "Datum": [], "Position": [], "Entscheidungen insgesamt": [], "Insgesamt_monat": [], "Asylberechtigt": [] } 
lastCountry = "" 

with open('test.csv') as csv_file: 
    for row in csv.DictReader(csv_file): 

     country['Datum'].append(row['Datum']) 
     country['Position'].append(row['Position']) 
     country['Entscheidungen insgesamt'].append(row['Entscheidungen insgesamt']) 
     country['Insgesamt_monat'].append(row['Insgesamt_monat']) 
     country['Asylberechtigt'].append(row['Asylberechtigt']) 

     if output.has_key(row['Herkunft']): 
      output[row['Herkunft']].update(country) 
     else: 
      country.clear() 
      country = {"Datum": [row['Datum']], "Position": [row['Position']], "Entscheidungen insgesamt": [row['Entscheidungen insgesamt']], "Insgesamt_monat": [row['Insgesamt_monat']], "Asylberechtigt": [row['Asylberechtigt']] } 
      output[row['Herkunft']] = country 

    print(json.dumps(output, indent=4)) 
# with open('data.txt', 'w') as outfile: 

Come si può vedere tutti i paesi tranne un paese non ottengono i dati dal csv. Dov'è l'errore. Come posso esportare il json? In realtà sto copiando il testo nel mio editor Editor

Answer 1

Nel codice, il problema è alla clausola di else: Quello che hai fatto:

1. Resetta country - questo rimuovere la riga appena aggiornato
2. Quindi aggiornare output, in questo momento , la tua country è già vuoto

Quello che vi serve è quello di:

1. accodamento country to output`
2. Azzera country
3. Quindi aggiornare country con la riga corrente

L'ordine è importante.

Ecco il codice:

import csv 
import json 

output = {} 
country = {} 

with open('test.csv') as csv_file: 
    for row in csv.DictReader(csv_file): 
     if not output.has_key(row['Herkunft']): 
      output[row['Herkunft']] = country 
      country = {"Datum": [], "Position": [], "Entscheidungen insgesamt": [], "Insgesamt_monat": [], "Asylberechtigt": [] } 

     country['Datum'].append(row['Datum']) 
     country['Position'].append(row['Position']) 
     country['Entscheidungen insgesamt'].append(row['Entscheidungen insgesamt']) 
     country['Insgesamt_monat'].append(row['Insgesamt_monat']) 
     country['Asylberechtigt'].append(row['Asylberechtigt']) 
     output[row['Herkunft']] = country 

    output[row['Herkunft']] = country # Catch the last country 
    print json.dumps(output, indent=4) 

Answer 2

Il tuo rientro è sbagliato. Ora apri il file di uscita e scrivici su ogni paese. Quindi, ogni paese ha la precedenza sull'output del precedente. [EDIT]: altri problemi. Usi il country ditt in modo strano lì. Ecco una versione migliore.

import csv 
import json 

output = {} 

with open('test.csv') as csv_file: 
    for row in csv.DictReader(csv_file): 
     if row['Herkunft'] in output: 
      country = output[row['Herkunft']] 
     else: 
      country = { "Datum": [], "Position": [], "Entscheidungen insgesamt": [], "Insgesamt_monat": [], "Asylberechtigt": [] } 
      output[row['Herkunft']] = country 
     country['Datum'].append(row['Datum']) 
     country['Position'].append(row['Position']) 
     country['Entscheidungen insgesamt'].append(row['Entscheidungen insgesamt']) 
     country['Insgesamt_monat'].append(row['Insgesamt_monat']) 
     country['Asylberechtigt'].append(row['Asylberechtigt']) 

print(json.dumps(output, indent=4)) 
with open('data.txt', 'w') as outfile: 
    outfile.write(json.dumps(output, indent=4))
