In this article, we’ll explore the Python for loop in detail and learn to iterate over different sequences including lists, tuples, and more. Additionally, we’ll learn to control the flow of the loop using thebreak and continue statements. When to use for Loop Anytime you have need to...
Next, we used the for loop to iterate over the numbers produced by the range() function In the body of a loop, we printed the current number. for num in range(10): print(num) Run Output: 0 1 2 3 4 5 6 7 8 9 for loop with range() The range() function returns a sequence...
# iterate from i = 0 to 3 for _ in range(0, 4: print('Hi') Run Code Output 0 1 2 3 Here, the loop runs four times. In each iteration, we have displayed Hi. Since we are not using the items of the sequence(0, 1, 2 and 4) in the loop body, it is better to use _...
print(character) ... a b c d e >>> for index in range(5): ... print(index) ... 0 1 2 3 4 In these examples, you iterate over a tuple, string, and numeric range. Again, the loop traverses the sequence in the order of definition.Note...
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 ...
for i in a: print i 1. 2. 3. Output 输出量 Here, a variable ‘a’ is defined with 5 values. The for loop here doesn’t check any condition as in case of a while loop. It just follows the sequence of a variable. We have also declared a counter variable ‘i’ which iterates ...
forxinrange(2,30,3): print(x) Try it Yourself » Else in For Loop Theelsekeyword in aforloop specifies a block of code to be executed when the loop is finished: Example Print all numbers from 0 to 5, and print a message when the loop has ended: ...
if the suite inserts an item in the sequence before the current item, the current item will be treated again the next time through the loop. This canlead to nasty bugs that can be avoided by making a temporary copy using a slice of the whole sequence, e.g., for x in a[:]: if...
了解Python控制流语句——for 循环 for循环 Python教程中for...in语句是另一种循环语句,其特点是会在一系列对象上进行迭代(Iterates),意即它会遍历序列中的每一个项目。我们将在后面的Python序列(Sequences)章节中了解有关它的更多内容。现在你所需要的就是所谓队列就是一系列项目的有序集合。
英文: Original Sinmilarly, using While and For loops,you can iterate tuples, dictionaries, and sets.These are called iterables.Iterables has many values within itself,so a loop control structure can iterate through every item inside the iterable. ...
