Using the same algorithm (see the other answers for better approaches), you can use itertools.count to get a loop that runs forever. import itertools for x in itertools.count(1): for y in xrange(1, x): for z in xrange(1, y): if x*x == y*y + z*z: print x, y, z 回复...
Let’s get started with the most important question: What is a “Foreach Loop”? Definition: Aforeachorfor eachloop is a programming control flow statement for iterating over elements in a sequence or collection. Unlike other loop constructs, theforeachloop iterates over all elements rather t...
Here the main catch in the question is “one pass”. What does it mean? It means you get to traverse the list only once and there’s no coming back to a node once you’ve traversed it. But to calculate the middle element you will require the length of the entire LinkedList, right?
This is why it is necessary to test each and every component properly so that we know which component might be highly responsible for the failure of the software.7. What is break, continue and pass in Python?Break The break statement terminates the loop immediately and the control flows to ...

>>> my_squares_list = [x*x for x in my_input_numbers] So another question the interviewer could ask is: what’s the difference between these two methods and what’s the best one? The answer here is that while list comprehension creates a list, the map function simply returns a map ...
