In conclusion, looping statements in Python are a crucial component as They enable the programmer to repeat a set of instructions until a specific condition is met, which helps to simplify complex problems and avoid repetitive code. There are three types of looping Statements in Python: for loop...

Python -- 循环技巧(Looping Techniques) 1.当想同时得到索引和对应的值时,可以用enumerate()函数 1 2 3 4 5 for i, v in enumerate(['tic', 'tac', 'toe']): print i, v 0 tic 1 tac 2 toe 2.要同时循环两个或多个序列,可以与zip()函数配对。 1 2 3 4 5 6 7 8 9 questions = ['...
In Python 2.2, withfrom _ _future_ _ import generators, you can also use: def Indexed(sequence): iterator = iter(sequence) for index in indices: yield iterator.next( ), index # Note that we exit by propagating StopIteration when .next raises it!
