I have been trying to look for this specific question but I cannot seem to find it so apologies in advance if there has been a previous thread asking the same question.
I have a df with football seasons but the format is a bit awkward (see below). I want to create a new column that goes from year 1929 to 2020 (see 'season_new')
Season season_new
0 1929 1929
1 1929-30 1930
2 1930-31 1931
3 1931-32 1932
Anyone can help me?
Many thanks
