• Question 406:

  Refer to the exhibit.

  

  A REST API returns this JSON output for a GET HTTP request, which has been assigned to a variable called "vegetables". Using Python, which output is the result of this command?

  print(filter(lambda 1: 1[`type'] == `fruit', vegetables) [0][`items'][0] [`items'][0])

  A. {`color': `green', `items': [`kiwi', `grape']}

  B. [`kiwi', `grape']

  C. lettuce

  D. kiwi

  Correct Answer: D

  it is kiwi but that function is very syntactically wrong

  1) lambda functions can't be called integers, so it should be something like "lambda : ["type'"] == ..."

  2) filter() returns an iterator and is not directly subscriptable, meaning that you need to actually iterate over it:

  for item in filter(lambda name: name["type"] == "fruit", data):

  print(item)

  this returns: {'type': 'fruit', 'items': [{'color': 'green', 'items': ['kiwi', 'grape']}, {'color': 'red', 'items': ['strawberry', 'apple']}]}

  3) [0]['items'][0]['items'][0] is also syntactically incorrect since the outer-most object is a dictionary not a list, however:

  for item in filter(lambda name: name["type"] == "fruit", data):

  print(item['items'][0]['items'][0])

  does actually return "kiwi"
