The if statement in Python is similar to that found in other programming languages (such as Java). It's the backbone of the logical flow of most programs. Here's an example:Python Copy y = 6 if y % 2 == 0: print('Even') The output is:...
When a Python program is run, the code is executed from top to bottom. The flow of the program can be altered with various keywords, includingif/else,for,while, andmatch. The control flow structures can be used to executed code conditionally or multiple times. The if statement Theifkeyword...

Learn Control Flow in Python Learn Loops in Python Python Modules Python Script Summary Learn Control Flow in Python As we said earlier,control flowallows us to choose different outcomes depending on a given condition. Its most simple implementation in Python is anif / elseclause. The basic synt...
Python program control flow is regulated by various types ofconditional statements,loops, andfunctioncalls. By default, the instructions in a computer program are executed in a sequential manner, from top to bottom, or from start to end. However, such sequentially executing programs can perform onl...
和大多数语言一样,Python 循环同样支持 continue 和 break。这没什么好说的。Changing horses in midstream我们看一个有意思的例子。 Code>>> a=range(3) >>> for i in a: print i a=range(10) 0 1 2 >>> 你会发现在循环体内部对 a 的修改并没有起到作用,为什么会这样呢?改一下代码就明白了。

The programs we’ve written so far are straight-line programs that consist of a sequence of Python statements executed one after the other. The flow of execution is simply a straight sequence of statements, with no branching or looping back to previous statements. In this chapter, we look at...
Control Flow In the programs we have seen till now, there has always been a series of statements faithfully executed by Python in exact top-down order. What if you wanted to change the flow of how it works? For example, you want the program to take some decisions and do different things...
【GiantPandaCV导语】本文作为从零开始学深度学习编译器的番外篇,介绍了一下深度学习框架的Data Flow和Control Flow,并基于TensorFlow解释了TensorFlow是如何在静态图中实现Control Flow的。而对于动态图来说,是支持在Python层直接写Control Flow的,最后基于Pytorch介绍了如何将Python层的Control Flow导出到TorchScript模型以...
