Here, 100 is thestartvalue, 0 is thestopvalue, and-10is the range, so the loop begins at 100 and ends at 0, decreasing by 10 with each iteration. This occurs in the output: Output 100 90 80 70 60 50 40 30 20 10 When programming in Python,forloops often make use of therange()...

在很多的高级语言中都有for循环(for loop)。for语句是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to beexecutedrepeatedly。(作用:介绍了f...
In computer science, afor-loop(or simplyfor loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly。(作用:介绍了for循环是什么?) A for-loop has two parts: a header specifying the iteration, and a body which is executed once per iteration. (...
Write for loop to iterate a list, In each iteration, it will get the next number from a list, and inside the body of a loop, you can write the code to calculate the square of the current number. Example: Calculate the square of each number of list Python list is an ordered sequence...
For Loops in Python (Definite Iteration)Darren Jones04:27 Mark as Completed Supporting Material Recommended TutorialAsk a Question This lesson goes into the guts of the Pythonforloop and shows you how iterators work. You’ll learn how to create your own iterators and get values from them using...
Python "for" Loops: The Pythonic Way In this quiz, you'll test your understanding of Python's for loop. You'll revisit how to iterate over items in a data collection, how to use range() for a predefined number of iterations, and how to use enumerate() for index-based iteration. Ge...
for_loop_else.py #!/usr/bin/python words = ["cup", "star", "monkey", "bottle", "paper", "door"] for word in words: print(word) else: print("Finished looping") We go over the list of words with aforloop. When the iteration is over, we print the "Finished looping" message ...
I’ll explore iterators more in future articles. For now know that iterators are hiding behind the scenes of all iteration in Python. Even more on iterators If you’d like to dive a bit deeper into this topic, you might want to check out myLoop Better talkor myarticle of the same name...
for语句实际上解决的是循环问题。在很多的高级语言中都有for循环(for loop)。 for语句其实是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code ...
