Print all items, using a while loop to go through all the index numbers thislist = ["apple", "banana", "cherry"]i = 0 while i < len(thislist): print(thislist[i]) i = i + 1 Try it Yourself » Learn more about while loops in our Python While Loops Chapter.Looping...
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...
下面是循环取List中数据的流程图: flowchart TD start[Start] --> input_list{Input List} input_list --> |Initialize index| index(0) index --> |index < len(list)| loop loop --> |Get element at index| get_element get_element --> |Process element| process process --> update_index{Upd...
4- Use a “while loop” to print the values contained in “mylist”, one at a time. 1i =02whilei <len_mylist:3print('mylist','[',i,']','=',mylist[i])4i += 1 5- Create a numpy array using the values contained in “mylist”. Name it “myarray”. 1importnumpy as np...
If we want to iterate all the elements of the listmyListusing theforloop: 如果要使用for循环迭代列表myList所有元素: for i in myList: print (i) 1. 2. As we can see we are using a variablei, which represents every single element stored in the list, one by one. Our loop will run ...

# Python3 code to iterate over a list list= [1,3,5,7,9] # Usingforloopforiinlist: print(i) 输出: 1个3579 方法2:For循环和range() 如果我们要使用从数字x到数字y迭代的传统for循环。 # Python3 code to iterate over a list list= [1,3,5,7,9] ...
In Python, we use a for loop to iterate over sequences such as lists, strings, dictionaries, etc. For example, languages = ['Swift', 'Python', 'Go'] # access elements of the list one by one for lang in languages: print(lang) Run Code Output Swift Python Go In the above example...
sent = 'the sky is blue'# splitting the sentence into wordssent_split = sent.split()# extract each word with a loopfor i in sent_split:print(i)Out:theskyisblue While循环 与for循环类似，while循环重复执行一个代码块——只要条件为真。只有当循环条件为false时，循环才会中止。while循环的一般...
下面着重介绍一个在for loop中循环使用else语句的例子。else 中的语句会在循环正常执行完的情况下执行。 三、把else语句放进for loop 例5:我们写一个简单的奇数偶数判别代码: 输入: for i in list(range(10,20)): if i%2 == 0: print(i,'是偶数') ...
