并行迭代 我提过多次 “迭代” 这个词,可以看出它在 Python 中占有重要的位置,其实 “迭代” 在 Python 中的表现就是 for 循环,从对象中获得一定数量的元素。在这里我们介绍一个方便的技巧,在使用迭代的时候,可以通过 zip() 函数对多个序列进行并行迭代。请看下面的例子: >>> name = ['rocky','leey','zh...
Pythonin the second iteration. Goin the third iteration. for loop Syntax for val in sequence: # body of the loop Theforloop iterates over the elements ofsequencein order. In each iteration, the body of the loop is executed. The loop ends after the last item in the sequence is reached....
Python for loop with range() function Python range is one of thebuilt-in functions. When you want the for loop to run for a specific number of times, or you need to specify a range of objects to print out, the range function works really well. When working withrange(), you can pass...

我们都知道,在 Java 的时候如果需要使用 for loop 循环,首先需要定义一个 i,然后进行循环。 比如说,我们要循环 1 到 501,Java 的代码为: for(int i=1; i<501; i++) Python 把这个循环进行简化了。 我们可以使用下面的代码来在 Python 中执行循环:for i in range(1, 501): ...
In this article, you’ll learn what is for loop in Python and how to write it. We use a for loop when we want to repeat a code block a fixed number of times. A for loop is a part of a control flow statement which helps you to understand the basics of Python. Also, Solve:...
