Lettuce example using python and scenarios outline

1. Lettuce example using scenarios
outline:
El siguiente ejemplo tiene tres archivos, un feature y dos py. En el siguiente ejemplo
atacaremos la api del tiempo y comprobaremos que ciertos valores sean correctos. Para ello
utilizaremos lettuce con python. Además utilizaremos scenarios Outline.
Weather2.feature:
Feature: Check if the weather service works properly
In order to check the weather service
As beginner
I'll get some values and check if they are ok and if the temperature given is correct
Scenario Outline: Check if a city and and country given are correct
Given I access the url with http://api.openweathermap.org/data/2.5/weather
And the city is <city> and the country <country>
When I ask for the city and country name
Then I check if the city and country are correct
And I check if the status code is 200
Examples:
| city | country |
| London | GB |
| Madrid | ES |
| Barcelona | ES |
Scenario Outline: Check if a latitude and longitude given are correct
Given I access the url with http://api.openweathermap.org/data/2.5/weather
And the latitude is <latitude> and the longitude <longitude>
When I ask for the latitude and longitude
Then I check if the latitude and longitude are correct
And I check if the status code is 200
Examples:
| latitude | longitude |
| 51.51 | -0.13 |
| 40.42 | 3.7 |
| 10.13 | -64.7 |
Scenario Outline: Check if the temperature is correct given a city and a country
Given I access the url with http://api.openweathermap.org/data/2.5/weather
And the city is <city> and the country <country>
When I ask for the city and country name
Then I get the temperature look by city and country
Examples:

2. | city | country |
| London | GB |
| Madrid | ES |
| Barcelona | ES |
Scenario Outline: Check if the temperature is correct given the latitude and longitude
Given I access the url with http://api.openweathermap.org/data/2.5/weather
And the latitude is <latitude> and the longitude <longitude>
When I ask for weather information by latitude and longitude
Then I get the temperature look by latitude and longitude
Examples:
| latitude | longitude |
| 51.51 | -0.13 |
| 40.42 | 3.7 |
| 10.13 | -64.7 |
