• Using the following code, why can't I use Google trends-api PyTrends with 5 concatenated words element in a list?

  For reference, I am using this tutorial: https://towardsdatascience.com/a-very-precise-fast-way-to-pull-google-trends-data-automatically-4c3c431960aa

                                cat=CATEGORY,
                                gprop=SEARCH_TYPE)

  df_trends = pd.concat(dicti, axis=1)
  
  df_trends.columns = df_trends.columns.droplevel(0) #drop outside header
  df_trends = df_trends.drop('isPartial', axis = 1) #drop "isPartial"
  df_trends.reset_index(level=0,inplace=True) #reset_index
  df_trends.columns=['date','Nike-US','Adidas-US','Under Armour-US','Zara-US','H&M-US','Louis Vuitton-US','Nike-UK','Adidas-UK','Under Armour-UK','Zara-UK','H&M-UK','Louis Vuitton-UK',
  'Nike-Germany','Adidas-Germany','Under Armour-Germany','Zara-Germany','H&M-Germany','Louis Vuitton-Germany'] #change column names
  

  Why does it give me a list index out of range error when I use multiple words together like this:

  KEYWORDS=['Nike + Adidas + Puma','Adidas','Under Armour','Zara','H&M','Louis Vuitton'] 
  

  When I concat on the Google Trends website and use: 'Nike + Adidas + Puma' it still gives me a map and a historical frequency of that concatenated string. But why does it give a list out of range error when doing it in the KEYWORDS variable?

• I get "TypeError: list indices must be integers or slices, not str". How do I fix it?

  I am working on some code that will take the data from OpenWeatherMap.org and displays the weather. Here's what I have so far:

  import requests, json
  
  apikey = "7cb9becaea566cc27d69991c345fa129"
  base = "http://api.openweathermap.org/data/2.5/onecall?"
  lat = "censored"
  lon = "censored"
  compbase = f"{base}lat={lat}&lon={lon}&exclude=current,minutely,hourly&appid={apikey}"
  print(compbase)
  resp = requests.get(compbase)
  x = resp.json()
  daily = x["daily"]
  temp = daily["temp"]
  des = daily["weather"]
  currtemp = temp["morn"]
  currtemp = str(round(float(1.8)*(currtemp - 273) + 32, 1))
  currpres = day["pressure"]
  currpres = str(round(currpres/3386, 1))
  currhum = day["humidity"]
  feelslike = day["feels_like"]
  feelslike = str(round(float(1.8)*(feelslike - 273) + 32, 1))
  winds = str(round(float(y["wind_speed"]), 1))
  weatherdes = str(des["description"])
  if "alerts" in x:
      alerts = x["alerts"]
      aldes = alerts["description"]
      print()
      print("ALERT!!!!")
      print()
      print(f"Your WeatherWatcher program has been interuppted by {alerts['sender_name']}. Please pay attention closely.")
      print()
      print(str(aldes))
  print()
  print(f"It is currently {currtemp} degrees Fahrenheit outside.")
  print()
  print(f"It feels like {feelslike} degrees Fahrenheit outside.")
  print()
  print(f"The wind is blowing at {winds} MPH.")
  print()
  print(f"The pressure is at {currpres} inhg.")
  print()
  print(f"The humidity is at %{currhum}.")
  print()
  print(f"OpenWeatherMap describes this weather as {weatherdes}.")
  print()
  print("This data was brought to you by WeatherWatcher.")
  

  (Sorry, kinda long.)

  But when I run it, I get this:

  Traceback (most recent call last):
    File "C:\Users\ron83\OneDrive\Documents\weather.py", line 12, in <module>
      temp = daily["temp"]
  TypeError: list indices must be integers or slices, not str
  

  What did I do wrong? I know I didn't make it a string.
• How to implement recursive method **at** object initialization?

  Say I have the following object:

  const dog = {
    sound: 'woof',
    speak: function() {
      console.log(this.sound)
    }
  }
  

  How could I implement dog.speak recursively within the initial object literal declaration?

  I could accomplish this by defining the dog.speak method outside of the initial object literal. E.g.:

  const dog = {
    sound: 'woof'
  }
  
  const dog.speak = () => {
    console.log(dog.sound)
    window.setTimeout(dog.speak, 1000)
  }
  

  This works because there is no this concept here - the sound property explicitly belongs to dog. But I would prefer to define this all within the initial object literal.

  To do so, I would need to preserve the this context via .bind(). But I'm struggling to identify where I would .bind() dog as this before making the recursive function call.
• All combination for a natural number using recursive methot C#

  I have this code:

  private static IEnumerable<(string formula, int sum)> GenerateRecursive(int number)
  {
      if (number == 1)
          yield return ("1", 1);
      else
          foreach (var pair in GenerateRecursive(number - 1))
          {
              yield return ($"{pair.formula} - {number}", pair.sum - number);
              yield return ($"{pair.formula} + {number}", pair.sum + number);
          }
  }
  
  private static IEnumerable<string> SolveFor(int target, int count)
  {
      return GenerateRecursive(count)
        .Where(item => item.sum == target)
        .Select(item => $"{item.formula} = {item.sum}");
  }
  

  which gives you all the combination for a natural number from(1, 2 ,3..... , n) using addition and subtraction.

  For input is the number and the length for example:

  • length : 6
  • Number : 3

  And for the output:

  • 1 + 2 + 3 - 4 - 5 + 6 = 3
  • 1 + 2 - 3 + 4 + 5 - 6 = 3
  • 1 - 2 - 3 - 4 + 5 + 6 = 3

  I am wondering how can I do this without LINQ and Collections Generic and using just recursive method. Thank You.

• Which is better in OCaml pattern matching, `when` or `if-then-else`?

  Let's say we have a type called d:

  type d = D of int * int
  

  And we want to do some pattern matching over it, is it better to do it this way:

  let dcmp = function 
    | D (x, y) when x > y -> 1 
    | D (x, y) when x < y -> -1
    | _ -> 0
  

  or

  let dcmp = function 
    | D (x, y) -> 
      if x > y then 1 else if x < y then -1 else 0
  

  Just in general is better to match patterns with many "when" cases or to match one pattern and the put an "if-then-else" in it?

  And where can I get more information about such matters, like good practices in OCaml and syntactic sugars and such?
• OCaml A ref does not change its value despite I instructed it

  I have a real code but I made this sample to illustrate my issue. This is the code sample:

  let ejem n =
    let count = ref 0 in
    let rec aum n =
      if n = 0 then 0
        else (count := !count + 1; n + aum (n-1) )
    in (aum n, !count)
  

  I try to change the count value inside aum function but, despite the count is outside of this function, its value is always 0 once it finishes.

  Please, help me to get what the issue is
• OCaml Input types

  I am learning OCaml and so far I am having trouble to understand the concepts of types.

  For example, if we have this following code:

  # let func x = x;;
  val func : 'a -> 'a = <fun>
  

  From the official website, it tells me that 'a before the arrow is the unknown input type and 'a after the arrow is the output.

  However, when I try to use function composition:

  # let composition f x = f(x);;
  val composition : ('a -> 'b) -> 'a -> 'b = <fun>
  

  What ('a -> 'b) means? Is 'a related to f and 'b related to x?

  Another function composition that made me even more confused is:

  # let composition2 f x = f(f(x));;
  val composition2 : ('a -> 'a) -> 'a -> 'a = <fun>
  

  I don't really understand why we don't have the 'b in this case.

  Thank you in advance!
