Jakko Jakthat explanation was perfect, thank you, I could post the code but it's a bit long, and making it short would be quite hard cause of pygame and that sort of stuff, but if you don't mind looking into long codes iam all for it ...
Title: An integer is a perfect square after adding 100, and a perfect square after adding 168. What is the number? 程序分析：因为题目说明x是整数，但没有说明n和m一定大于零，此处考虑了n和m小于零的情形。 Program analysis:Because the title says that x is an integer, but it does not...
The longer versions (if tests, multiple for clauses) are also valid for sets: >>> a_set = {number for number in range(1,6) if number % 3 == 1} >>> a_set {1, 4} Generator Comprehensions Tuples do not have comprehensions! You might have thought that changing the square brackets...
