When you use a negative number as an index, Python counts backwards through the array, starting with -1 as the last item in the array. The following example accesses the last value stored in example_array: example_array[-1] 8 Python supports more advanced indexing through its slice ...
If we have a long string and we want to pinpoint an item towards the end, we can also count backwards from the end of the string, starting at the index number-1. For the same stringSammy Shark!the negative index breakdown is like this: ...
backwards compatibility is not important. For environments running a version of Python 2, converting using 2to3 will often break your program. If compatibility between environments is important for your organization, you will want to consider other libraries with an existing compatibility layer between...
Not all operations can be implemented in a lock-free manner. For example, if we wanted to count the number of occurrences of an element in a FIFO, or calculate a sum over all elements, this probably needs a lock over the entire FIFO. ...

t = (1,2,3,4,5) makes a tuple t[start:end:count] will used slice a list from start to end by incrementing counter for next element by count. And using negative numbers will retrieve list from backwards. So print( t[ : : -1]) will print tuple in reverse. Here start,...
