How to Repeat N Times in Python Using the itertools.repeat() FunctionPython’s itertools module provides another convenient function called repeat() to create an iterator that repeats elements from an iterable indefinitely.Syntax of the itertools.repeat() Functionitertools.repeat(element, times) ...
x = itertools.cycle("ABC") print(list(itertools.islice(x, 0, 10, 1))) # ['A', 'B', 'C', 'A', 'B', 'C', 'A', 'B', 'C', 'A'] # 简单的生成一个拥有指定数目元素的迭代器 x = itertools.repeat(0, 5) print(list(x)) # [0, 0, 0, 0, 0] 1. 2. 3. 4. 5....
