# Find every index of max value in a column in two-dimensional list

So I made this function to find what the max value of "column" is in my 2d-list, which returns the max value of my said column in my list, but this said max value actually appears twice, so how do I return the indexes/rows where this max value appears?

Cheers

``````def find_max(column):
maxVal = 0
for i in range(1, len(lst)):
maxVal = max(maxVal, int(lst[i][column]))
return (maxVal)
``````

I feel so lost, but i've been trying something like this.... v (obv not working atm, just brainstorming)

``````
def test(column):
maxVal = 0
year = []
for i in range(1, len(lst)):
if maxVal == int(lst[i][column]):
year.append(lst[i][0])
else:
maxVal = max(maxVal, int(lst[i][column]))
year = (lst[i][0])
year.extend(maxVal)
return year

#so column 0 is years, and I want to save the years where my X column had the biggest value(s).
``````

And lets say the column I'm looking for is the third (or index 2), so I have the max value of 27 on row 36 & 38, how do I return these indexes? (What im actually looking for is what the value on first column is, 2004 & 2006)
