I call an api via python and return this code as response:
{
"cast": [
{
"character": "Power",
"name": "George"
},
{
"character": "Max",
"job": "Sound",
"name": "Jash"
},
{
"character": "Miranda North",
"job": "Writer",
"name": "Rebecca"
}
]
}
I am trying to get the value of Rebecca because i need to get the Writer. So i wrote:
for person in cast # cast is the variable keeps whole code above NOT inside the dict:
if person["job"] == "Writer":
writer = person["name"]
but it gives me:
KeyError at search/15
u'job'
how can i get the value?
FULL CODE:
writer = ""
for person in api['cast']:
if person.get('job') == 'Writer':
writer = person.get('name')
return render(request, 'home.html', {
'writer': writer
})
home.html:
<p>{{writer}}</p>
That's because not all elements in the list have the job key.
Change to:
for person in cast #whole code above:
if person.get('job') == 'Writer':
writer = person.get('name')
One liner to find one writer.
writer = next((person for person in api['cast'] if person.get('job') == 'Writer'), None)
One liner to find all writers.
writers = [person for person in api['cast'] if person.get('job') == 'Writer']
Syntax for dictionary get() method:
dict.get(key, default=None)
Parameters
key: This is the Key to be searched in the dictionary.
default: This is the Value to be returned in case key does not exist.
You need to specify the default value for get in case the key doesn't exist.
>>> for person in api['cast']:
... if person.get('job', '') == 'Writer':
... writer = person.get('name')
