Describe the bug
While requesting to Spotify API recommendations(seed_genre=genre), the return is an HTTPError: 400 Client Error: Bad Request for url: https://api.spotify.com/v1/recommendations?seed_genres=t%2Ce%2Cc%2Ch%2Cn%2Co

I checked to Spotify Console (Get Recommendations Based on Seeds) and the right request should be: "https://api.spotify.com/v1/recommendations?seed_genres=techno"

Your code

genre='techno'

def get_recommendations(genre):
    recommendations = sp.recommendations(seed_genres=genre)
    return recommendations

print (get_recommendations(genre))

Expected behavior

{
  "tracks": [
    {
      "album": {
        "album_type": "SINGLE",
        "artists": [
          {
            "external_urls": {
              "spotify": "https://open.spotify.com/artist/0SfsnGyD8FpIN4U4WCkBZ5"
            },
            "href": "https://api.spotify.com/v1/artists/0SfsnGyD8FpIN4U4WCkBZ5",
            "id": "0SfsnGyD8FpIN4U4WCkBZ5",
            "name": "Armin van Buuren",
            "type": "artist",
            "uri": "spotify:artist:0SfsnGyD8FpIN4U4WCkBZ5"
          },
          {
            "external_urls": {
              "spotify": "https://open.spotify.com/artist/2r7POU2f5jV6x3k4vsNwrM"
            },
            "href":

and so on

Output
