Question

Language: Python

Topic: APIs and JSON

Function name: can_visit

Parameters: country_code (str), langList (list of strings )

Return: boolean

Description: You are looking for a country to visit for SB2K19 and want to ensure that you know how to speak at least one of the languages spoken in that country. Given a country_code (str), a three - letter code representing the country you want to visit, and a langList (list), a list of the names of the languages you know how to speak, develop a function that returns True if you can speak at least one of the languages spoken in the country represented by country _code or return False if you cannot speak any of the languages spoken in the country represented by country_code.

Hint: Using the Languages endpoint for this function will not work because the languages are passed in by their name not by their code.

Tes t Cases:

>>> result = can_visit("LBN", [“Python”, "Chinese", "Java", "French"]) >>> print(result)

True

>>> result = can_visit("PRT", ["Spanish", "English", "Arabic"])

>>> print(result)

False

   r = requests.get(url)
   data_dict = r.json()[0]
   lan_list = []
   for lan in data_dict['languages']:
       lan_list.append(lan['name'].lower())

   for lan in langList:
       if lan.lower() in lan_list:
           return True
