2. __next__（）：next方法返回可迭代对象的下一个值。当我们使用for循环来遍历任何可迭代对象时，它在内部使用iter（）方法来获取迭代器对象，迭代器对象进一步使用next（）方法进行迭代。此方法引发StopIteration以发出迭代结束的信号。Python iter()示例 string = "GFG"ch_it
string="GFG"ch_iterator = iter(string)print(next(ch_iterator))print(next(ch_iterator))print(next(ch_iterator)) 输出 GFG 使用iter()和next()创建迭代器 下面是一个简单的Python迭代器,它创建了一个从10到给定限制的迭代器类型。例如,如果限制是15,则它会打印10 11 12 13 14 15。如果限制是5,则它...

GFG: Practice Problems based on Maths for DSA3.2 ArrayThe array is a fundamental and crucial data structure, presenting a linear arrangement of elements. It serves as a collection of homogeneous data types, with elements allocated contiguous memory. Thanks to this contiguous allocation, accessing any...
