Slice notation is a syntax feature in Python that allows you to extract a specific subset of a sequence. You can use slice notation with any sequence in Python, including strings, lists, and tuples. Slice notation returns a new sequence that is a subset of the original sequence. You can ...
Python lists are: Ordered collections of arbitrary objects Accessed by offset Arrays of object references Of variable length, heterogeneous, and arbitrarily nestable Of the category, mutable sequence Data types in which elements are stored in the index basis with starting index as 0 Enclosed between ...

using its position or index number. Indexing in Python starts at 0, which means that the first element in a sequence has an index of 0, the second element has an index of 1, and so on. For example, if we have a string "Hello", we can access the first letter "H" using its inde...

The array in C++ is a useful data structure for representing a sequence of elements. By using an array, you can easily store and access data in a structurally consistent way. It is very important to understand how an array works in C++ to use it to its full potential. This will help ...
A struct_time is a type of time value sequence with a named tuple interface returned by gmtime(), localtime(), and strptime(): import time as time_module utc_time_in_seconds = time_module.gmtime() print("Time struct in UTC", utc_time_in_seconds) Here’s the output of the code ...
