Iterators in C++ with Examples - Dot Net Tutorials
WebWe can do that using Dictionary Comprehension. First, zip the lists of keys values using the zip () method, to get a sequence of tuples. Then iterate over this sequence of tuples using a for loop inside a dictionary comprehension and for each tuple initialised a key value pair in the dictionary. All these can be done in a single line using the ... WebMay 4, 2016 · Before c++17 inheritance from std::iterator was encouraged to remove the tedium from iterator boilerplate implementation.
