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()...
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. (...
Flow chart of a for loop Why use for loop? Let’s see the use for loop in Python. Definite Iteration: When we know how many times we wanted to run a loop, then we use count-controlled loops such as for loops. It is also known as definite iteration. For example, Calculate the perc...
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 be...
/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 which is located in ...
这整个吃过程叫做一个循环(loop),每吃一次的过程叫做一次迭代(iteration)。某些人把loop和iteration都翻译做循环,其实他们是有差异的,就像method和function(method和function的差异还没这么大)。 在正式介绍循环语句之前,我们先学点预备知识。 函数 什么是函数?这是一个不太好回答的问题。我们暂且把函数理解为‘我们...
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...

Loop iteration: 1 Loop iteration: 2 Loop iteration: 3 Loop iteration: 4 1. 2. 3. 4. 5. 这表明循环成功执行了5次,符合我们的预期。 总结 通过以上步骤,我们成功地实现了在Python中循环固定次数的功能。在这篇文章中,我向你展示了整个过程的流程,并提供了详细的代码示例和注释。希望这篇文章对你理解和...
