Python循环语句之break与continue的用法
Python break 语句
Python break语句，就像在C语言中，打破了最小封闭for或while循环。
break语句用来终止循环语句，即循环条件没有False条件或者序列还没被完全递归完，也会停止执行循环语句。
break语句用在while和for循环中。
如果您使用嵌套循环，break语句将停止执行最深层的循环，并开始执行下一行代码。
Python语言 break 语句语法：
break
流程图：
实例：
#!/usr/bin/python for letter in 'Python': # First Example if letter == 'h': break print 'Current Letter :', letter var = 10 # Second Example while var > 0: print 'Current variable value :', var var = var -1 if var == 5: break print "Good bye!"
以上实例执行结果：
Current Letter : P Current Letter : y Current Letter : t Current variable value : 10 Current variable value : 9 Current variable value : 8 Current variable value : 7 Current variable value : 6 Good bye!
Python continue 语句
Python continue 语句跳出本次循环，而break跳出整个循环。
continue 语句用来告诉Python跳过当前循环的剩余语句，然后继续进行下一轮循环。
continue语句用在while和for循环中。
Python 语言 continue 语句语法格式如下：
continue
流程图：
实例：
#!/usr/bin/python # -*- coding: UTF-8 -*- for letter in 'Python': # 第一个实例 if letter == 'h': continue print '当前字母 :', letter var = 10 # 第二个实例 while var > 0: var = var -1 if var == 5: continue print '当前变量值 :', var print "Good bye!"
以上实例执行结果：
当前字母 : P 当前字母 : y 当前字母 : t 当前字母 : o 当前字母 : n 当前变量值 : 9 当前变量值 : 8 当前变量值 : 7 当前变量值 : 6 当前变量值 : 4 当前变量值 : 3 当前变量值 : 2 当前变量值 : 1 当前变量值 : 0 Good bye!

What is the function of C language sum?
Apr 03, 2025 pm 02:21 PM
There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.
Is the conversion speed fast when converting XML to PDF on mobile phone?
Apr 02, 2025 pm 10:09 PM
The speed of mobile XML to PDF depends on the following factors: the complexity of XML structure. Mobile hardware configuration conversion method (library, algorithm) code quality optimization methods (select efficient libraries, optimize algorithms, cache data, and utilize multi-threading). Overall, there is no absolute answer and it needs to be optimized according to the specific situation.
How to convert XML files to PDF on your phone?
Apr 02, 2025 pm 10:12 PM
It is impossible to complete XML to PDF conversion directly on your phone with a single application. It is necessary to use cloud services, which can be achieved through two steps: 1. Convert XML to PDF in the cloud, 2. Access or download the converted PDF file on the mobile phone.
Is there any mobile app that can convert XML into PDF?
Apr 02, 2025 pm 08:54 PM
An application that converts XML directly to PDF cannot be found because they are two fundamentally different formats. XML is used to store data, while PDF is used to display documents. To complete the transformation, you can use programming languages and libraries such as Python and ReportLab to parse XML data and generate PDF documents.
How to convert xml into pictures
Apr 03, 2025 am 07:39 AM
XML can be converted to images by using an XSLT converter or image library. XSLT Converter: Use an XSLT processor and stylesheet to convert XML to images. Image Library: Use libraries such as PIL or ImageMagick to create images from XML data, such as drawing shapes and text.
How to control the size of XML converted to images?
Apr 02, 2025 pm 07:24 PM
To generate images through XML, you need to use graph libraries (such as Pillow and JFreeChart) as bridges to generate images based on metadata (size, color) in XML. The key to controlling the size of the image is to adjust the values of the <width> and <height> tags in XML. However, in practical applications, the complexity of XML structure, the fineness of graph drawing, the speed of image generation and memory consumption, and the selection of image formats all have an impact on the generated image size. Therefore, it is necessary to have a deep understanding of XML structure, proficient in the graphics library, and consider factors such as optimization algorithms and image format selection.
Recommended XML formatting tool

XML formatting tools can type code according to rules to improve readability and understanding. When selecting a tool, pay attention to customization capabilities, handling of special circumstances, performance and ease of use. Commonly used tool types include online tools, IDE plug-ins, and command-line tools.
What is the process of converting XML into images?
Apr 02, 2025 pm 08:24 PM
To convert XML images, you need to determine the XML data structure first, then select a suitable graphical library (such as Python's matplotlib) and method, select a visualization strategy based on the data structure, consider the data volume and image format, perform batch processing or use efficient libraries, and finally save it as PNG, JPEG, or SVG according to the needs.
