0 Python 1 R 2 Julia”’ Strengths and Weaknesses of the enumerate() Function in Python Strengths: enumerate() is a Pythonic way of counting the list of objects. It avoids the use of for loop and thus makes the code a little bit cleaner. enumerate() has the flexibility to start count...
enumerate(iterable, start=0) Here, iterable is the sequence that you want to iterate over, and start is an optional parameter that specifies the starting value of the index. The default value of the start is 0. Parameters of Enumerate Function The enumerate() function in Python has two para...

The enumerate() function returns an enumerate object. iterable must be a sequence, an iterator, or some other object which supports iteration. Note: The __next__() method of the iterator returned by enumerate() returns a tuple containing a count (from start which defaults to 0) and the v...

函数是python为了代码最大程度地重用和最小化代码冗余而提供的基本程序结构。函数是一种设计工具,它能让程序员将复杂的系统分解为可管理的部件; 函数用于将相关功能打包并参数化。在python中可以创建如下4种函数: 1)、全局函数:定义在模块中(直接定义在模块中的函数)。 2)、局部函数:嵌套于其它函数中(在函数中再...
