Hello,
Here’s what I am trying to do (Col2 is the desired result)
Col1 Col2
100 1
100 2
100 3
101 1
102 1
102 2
102 3
102 4
102 5
103 1
103 2
I try to ennumerate the occurrances of values of Col1, here’s the code I tried
data['Col2'] = list(enumerate(data['col1'], 1))
but it simply creates a list.
I would be grateful if anyone could shed some light on this.
Sincerely,
Josep Maria
