So I managed to find how do extract part of the data you want to use / analyse.

You should simply call the column you are trying to extract (in my case system_name) and give its value (in my case "Métro de Paris"). Here The dataframe, data, will now have the data with value "Métro de Paris" form the column "system_name".

"articles.map is not a function". means that articles need to be an array. You can only map over an array in Javascript.

and indeed, first JSON (when parsed) is an array. It starts with [ and ends with ]. Inside of this array, there is one or more objects.

Second JSON is just an object. You are receiving object from the api, as they are adding some more information such as status and totalResults. You can use status property to know the status of the response, and totalResults for pagination purposes, for example. Then they give you the array of articles you are looking for.

You can only map via this array.

So assuming you store the result of the api call in variable data, your map function would look like: data.articles.map((element) => {... do something with element ... })

When your if-statement is executed, you return a list of items and feed them into the display_tracks() function. But what happens when the else-statement is executed? You add the request to your text-file, but do not return anything (or a NoneType item) and feed that into display_tracks(). display_tracks then iterates of this NoneType-item, throwing your exception.

You only want to show the tracks if there actually are any tracks to display. One way to do this would be to move the call of display_tracks() into your main function, but then the same error would be thrown if no tracks are found to your search-terms. Another solution would be to first check if your tracks are not empty or to catch the TypeError-exception with something like

You haven't initialized the tinderPagesList variable.

You need to initialize it first then you can add. Do like this:

You need to add migration after this change and run Update-Database in package manager console to apply these changes

After ALTER you create new records with INSERT. If you want pair your cities with existing records, you must identify it:

Define your method get_sentiment as the following:

I found the solution myself:

Strings are iterable in Python, and you're iterating over each character inside the list comprehension and running re.sub in those characters separately.

Also, you don't need Regex here. Use str.replace:
