[FBRef] read_player_season_stats includes Women's World Cup by default (season 2023)

[mvantschip]

I am fetching player data for the 2023 season, which by default, according to the docs, should only return data from the top 5 leagues. However, I noticed that stats from the Women's World Cup are included as well.
I can reproduce this issue with the following code:

import soccerdata as sd
import pandas as pd

fbref = sd.FBref(seasons=2023)
stats = fbref.read_player_season_stats(stat_type='standard')
print(stats.index.unique(level='league'))

Output:

Index(['ENG-Premier League', 'ESP-La Liga', 'FRA-Ligue 1', 'GER-Bundesliga',
       'INT-Women's World Cup', 'ITA-Serie A'],
      dtype='object', name='league')`

In addition, I get a dataframe where each row occurs twice, but I am not sure if that problem is related.
See, from the same code, the output of stats.head():

import soccerdata as sd
import pandas as pd

fbref = sd.FBref(seasons=2023)
stats = fbref.read_player_season_stats(stat_type='standard')
print(stats.head())

Output:

Thanks for the wonderful work!

The docs are outdated. When no leagues are given, it returns the data for all the supported leagues. Previously, only the Big 5 leagues were supported but I've added support for the World Cups and Euros since.

I see! Thanks. Any idea about the duplicate rows? Or should I make a separate issue for that?
