python缩进区别分析

python indentation

仔细观察下面两个python程序,代码一模一样,但是运行的结果却不同,就是因为最后一行return缩进的不同

代码如下:


def powersum(power, *args):

'''Return the sum of each argument raised to specified power.'''
total = 0
for i in args:
total += pow(i, power)
return total


运行时输入powersum(2,3,4)输出25(3的平方加上4的平方)

代码如下:


def powersum(power, *args):
'''Return the sum of each argument raised to specified power.'''
total = 0
for i in args:
total += pow(i, power)
return total


运行时输入powersum(2,3,4)输出9(3的平方)

由此可见,对于python编写代码时,不能随意的缩进

Is there any mobile app that can convert XML into PDF? 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 control the size of XML converted to images? 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.

Is the conversion speed fast when converting XML to PDF on mobile phone? 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.

Is there a mobile app that can convert XML into PDF? Is there a mobile app that can convert XML into PDF? Apr 02, 2025 pm 09:45 PM

There is no APP that can convert all XML files into PDFs because the XML structure is flexible and diverse. The core of XML to PDF is to convert the data structure into a page layout, which requires parsing XML and generating PDF. Common methods include parsing XML using Python libraries such as ElementTree and generating PDFs using ReportLab library. For complex XML, it may be necessary to use XSLT transformation structures. When optimizing performance, consider using multithreaded or multiprocesses and select the appropriate library.

How to modify node content in XML How to modify node content in XML Apr 02, 2025 pm 07:21 PM

XML node content modification skills: 1. Use the ElementTree module to locate nodes (findall(), find()); 2. Modify text attributes; 3. Use XPath expressions to accurately locate them; 4. Consider encoding, namespace and exception handling; 5. Pay attention to performance optimization (avoid repeated traversals)

What is the process of converting XML into images? 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.

How to convert xml format to html How to convert xml format to html Apr 02, 2025 pm 08:57 PM
