We go over the list of words with aforloop. When the iteration is over, we print the "Finished looping" message which is located in the body following theelsekeyword. $ ./list_loop_for2.py cup star falcon cloud wood door Finished looping Python list loop with enumerate Theenumeratefunctio...
for loop with enumerate() Normal for loop: names = ['Alice','Bob','Charlie']fornameinnames:print(name)# Alice# Bob# Charlie While by passing an iterable object in the argument ofenumerate(), you can getindex, element. fori, nameinenumerate(names):print(i, name)# 0 Alice# 1 Bob#...
In theforloop in this example, you nestzip()insideenumerate(). This means that each time theforloop iterates,enumerate()yields a tuple with the first value as the count and the second value as another tuple containing the elements from the arguments tozip(). To unpack the nested structure...
标准for循环适用于简单的迭代遍历,enumerate()函数适用于需要同时获取索引和值的情况,zip()函数适用于同时迭代多个可迭代对象的情况。在腾讯云平台中,可以通过云服务器CVM、云数据库MySQL、云函数SCF、对象存储COS、云物联IoT Hub等产品来支持不同场景下的开发和部署需求。 相关搜索: php loop语法 matlab for loop ...
Process finished with exit code1 for 语句 Python for循环可以遍历任何序列的项目,如一个列表或者一个字符串。 for循环的一般格式如下: 1 2 3 4 for<variable>in<sequence>: <statements> else: <statements> Python loop循环实例: 实例 1 2 3
To learn more about loops, visitPython for loop. Access the Next Element In Python, we can use thenext()function to access the next element from an enumerated sequence. For example, grocery = ['bread','milk','butter'] enumerateGrocery = enumerate(grocery) ...
The enumerate() function in Python returns an enumerate object, which is an iterator that generates a sequence of tuples. Each tuple contains two values: the index of the current item in the sequence and the item itself. You can use this enumerate object directly in a loop, or you can ...
1. 枚举 -enumerate可以有参数哦 之前我们这样操作: i = 0 for item in iterable: print i, item i += 1 现在我们这样操作: for i, item in enumerate(iterable): print i, item enumerate函数还可以接收第二个参数。就像下面这样: >>> list(enumerate('abc')) ...
1、enumerate(iterable,start=0) enumerate()是python的内置函数,是枚举、列举的意思 对于一个可迭代的(iterable)/可遍历的对象(如列表、字符串),enumerate将其组成一个索引序列,利用它可以同时获得索引和值 在python中enumerate的用法多用于在for循环中得到计数 ...
