First, we need to set up a simple decision tree for our BFS to search. Next, we’ll define this simple decision tree using a Python dictionary, where each key is a node, and its value is a list of the node's children. # Define the decision tree as a dictionary tree = { 'A':...

whenever a Python program encounters the continue statement in a loop, it skips the remainder of the body of the loop and begins the next iteration. One can also combine the last three lines of code into one using the lists’s extend function in combination with a list comprehension. This ...
