Besides this, there is another way of doing it. If you can recall, our old traditional way of accessing an element of the list by index -myList[i]. Although, in this case, we will be using another functionrange()(or alternativelyxrange()can also be used).range()function has already ...
在使用for循环的Python中,list是一种有序的可迭代对象,它可以存储多个元素。list可以包含不同类型的元素,例如整数、浮点数、字符串等。 当使用for循环遍历一个list时,Python会按照list中元素的顺序依次取出每个元素,并执行相应的操作。for循环会自动迭代list中的每个元素,直到遍历完所有元素为止。 下面是list...
Python list loop with while The while statement is a control flow statement that allows code to be executed repeatedly based on a given boolean condition. list_loop_while.py #!/usr/bin/python vals = [1, 2, 3, 4, 5, 6, 7] n = len(vals) i = 0 mysum = 0 while i < n: mys...

languages = ['Swift', 'Python', 'Go'] # using _ for placeholder variable for _ in languages: print('Hi') Here, the loop still runs three times because there are three elements in thelanguageslist. Using_indicates that the loop is there for repetition and not for accessing the elements...
Below are the few examples of Python list. numers = [1,2,4,6,7] players = ["Messi", "Ronaldo", "Neymar"] Using a loop, we can perform various operations on the list. There are ways to iterate through elements in it. Here are some examples to help you understand better. Example ...
You can use list comprehension to get the for loop in one line. Alist comprehensionis a concise and elegant way to create a new list from an existing list in Python. With list comprehension, you can create a new list by applying specific operations on each element of the existing list. ...
ListsandTuplesare iterable objects. Let’s look at how we can loop over the elements within these objects now. words=["Apple","Banana","Car","Dolphin"]forwordinwords:print(word) Copy Output: Apple Banana Car Dolphin Copy Now, let’s move ahead and work on looping over the elements of...
Example 1: Double the Elements of a List Using the One-Line “For” Loop If you have an old list and you want to operate on it to double the value of its elements, you can use the following method to do it using the list comprehension. ...
