get max index
Try this : l = [1, 3, 2, 2, 1, 1, 1, 2, 3, 2, 1, 1, 1, 3, 1, 1, 3] mx = max(l) m = [i for i,j in enumerate(l) if j==mx]. OUTPUT : [1, 8, 13, 16].,Say that you have a list values = [3,6,1,5] , and need the index of the smallest element, i.e. ... This way the list will only be traversed once for min (or max). ,You can find the min/max index and value at the same time if you enumerate the items in the list, but perform min/max on the original values of the list. Like so: , The function is max . To obtain the first maximum value you should do [val, idx] = max(a);. val is the maximum value and idx is its index., Without any information about the content of the array, you must check each element to find the maximum value, and the corresponding index., SELECT MIN(b), MAX(b) FROM tbl WHERE a = 12; ... The query looks in the index for a = 12 , grabs the first (a,b) pair to get MIN(b) and grabs ...,Returns the indices of the maximum values along an axis. ... axis : int, optional. By default, the index is into the flattened array, otherwise along the specified axis. , Use argmax() idxmax() to get the index of the max value. Then you can use loc df.loc[df['favcount'].idxmax(), 'sn']. Edit: argmax() is now ...,Return the maximum value in a Series. DataFrame.max. Return the maximum values in a DataFrame. Examples. >>> idx = pd.Index([3, 2, 1]) >>> idx.max() 3. > ... , There are many options, for example: import operator index, value = max(enumerate(my_list), key=operator.itemgetter(1)).
