A protip by juliengarcia about python, list, and slice. Since I start to code in Python, I like the way the list are managed. When you code in Java (version 6) for example and you want to get on the odd/even indexed values (as making x_y points from csv format), you need to go trough all the values and do the check:. int[] point_csv_array = {5, 12, 3, 21, 8, 7, 19, 102 }; //you want array_X

index=mylist.index(item).

Indexing using index arrays Indexing can be done in numpy by using an array as an index. In case of slice, a view or shallow copy of the array is returned but in index array a copy of the original array is returned. Code Python If you want to find the substring or character in the string, there are two methods- index () and find (). Both of these methods return the index of the substring if the substring you want to search is present in the given string. Example of index () and find () method index() method in Python. Just like find(), index() method determines the position at which a substring is first found in a string. In the same way index() takes 3 parameters: substring that is to be searched, index of start and index of the end(The substring is searched between the start and end indexes of the string) out of which indexes of Python string method rindex() returns the last index where the substring str is found, or raises an exception if no such index exists, optionally restricting the search to string[beg:end].

In Python, one computes the minimum of a list with the built-in function min.. Now, what if, in addition to the value of a minimum element, we also need to compute an index of such an element in the list?
