I'm trying to merge two dfs (basically th same df at different time) using pd.concat.
here is my code:
Aujourdhui = datetime.datetime.now()
Aujourdhui = (Aujourdhui.strftime("%X"))
PerfsL1 = pd.read_html('https://fbref.com/fr/comps/13/stats/Statistiques-Ligue-1#all_stats_standard', header=1)[0]
PerfsL1.columns = ['Équipe', 'Used_players', 'age', 'Possesion', "nb_matchs", "Starts", "Min",
'90s','Buts','Assists', 'No_penaltis', 'Penaltis', 'Penaltis_tentes',
'Cartons_jaunes', 'Cartons_rouges', 'Buts/90mn','Assists/90mn', 'B A /90mn',
'NoPenaltis/90mn', 'B A P/90mn','Exp_buts','Exp_NoPenaltis', 'Exp_Assists', 'Exp_NP A',
'Exp_buts/90mn', 'Exp_Assists/90mn','Exp_B A/90mn','Exp_NoPenaltis/90mn', 'Exp_NP A/90mn']
PerfsL1.insert(0, "Date", Aujourdhui)
print(PerfsL1)
PerfsL12 = pd.read_csv('Ligue_1_Perfs.csv', index_col=0)
print(PerfsL12)
PerfsL1 = pd.concat([PerfsL1, PerfsL12], ignore_index = True)
print (PerfsL1)
I successfully managed to get both df individually which are sharing the same columns, but I can't merge them, getting
ValueError: no types given.
Do you have an idea where it could be coming from ?
EDIT Here are both dataframes:

Thanks you for your support and have a great day !

Please show a example of "Ligue_1_Perfs.csv".

Your code should work.
Nevertheless, try this before the concat:
PerfsL1 = PerfsL1.reset_index()
PerfsL2 = PerfsL2.reset_index()
