Then I have a following python code to open and load this .json file. The idea is that when user pass a parameter via terminal or command line- program should check it and if its equal to one of the keys- it will print all the official country names under that key. By keys I mean ces, deu,cym, which are attributes of translation.
Here is the code I wrote:
import json
import sys
from sys import argv
import json
#access .json file and load it's insides
with open('countries.json') as f:
countries = json.load(f)
#create a list of translation keys from .json file
official_keys = {}
for c in countries:
official_keys[c['name']['official']] = c['translations']
if len(sys.argv) == 1 or len(sys.argv) > 2:
print("Incorrect parameter")
sys.exit()
else:
key = argv[1]
#return countries names if CLI pAarameter matches one of the keys
for official, keys in official_keys.items():
if (key in keys):
print(keys[key]["official"])
else :
print ("Translation key is not supported")
break
It is working fine for keys that are appear in every translation, but as you can see, cym key is not appearing in the first translations, that's why when I execute python3 main.py cym it returns "Translation key is not supported". I wrote the same project in Javascript before and it was easier there by using Optional Chaining. It would allow me to return Translation key is not supported for the first country, but instead of crushing, program would go search and return those elements that actually appear.
This is the part of Javascript code:
try {
for (const {translations} of data) {
const key = translations[enteredKey]?.official;
if (key) {
console.log(key);
}
}
} catch (error) {
console.log('Cannot translate variable');
}
Can anyone help me modify this python code not to crush after not finding key element in one of the translations?
CodePudding user response：
Instead of replacing the translations dictionary each time, merge them using the update() method.
official_keys = {}
for c in countries:
official_keys.setdefault(c['name']['official'], {}).update(c['translations'])
