Two real-life solutions to value error reporting and encoding error reporting in Python when processing JSON
Two real-life solutions to value error reporting and encoding error reporting in Python when processing JSON
1、ValueError: Invalid control character at: line 1 column 8363 (char 8362)
使用json.loads(json_data)时，出现：
ValueError: Invalid control character at: line 1 column 8363 (char 8362)
出现错误的原因是字符串中包含了回车符（\r）或者换行符（\n）
解决方法：
(1)对这些字符转义：
json_data = json_data.replace('\r', '\\r').replace('\n', '\\n')
(2)使用关键字strict:
json.loads(json_data, strict=False)
strict默认是True,它将严格控制内部字符串，将其设置为False,便可以允许你\n \r。
2、UnicodeEncodeError: ascii codec can't encode错误
在windows下写的python脚本，放到linux下运行，直接报：
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-11: ordinal not in range(128)
解决方法：
（1）临时解决方法：
在代码前加入：
import sys
reload(sys)
sys.setdefaultencoding('utf8')
（2）一劳永逸：
在Python的lib\site-packages文件夹下新建一个sitecustomize.py，内容如下：
# encoding=utf8
import sys
reload(sys)
sys.setdefaultencoding('utf8')
这样的话，系统在Python启动的时候，自行调用该文件，设置系统的默认编码。

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 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.
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 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

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.
Recommended XML formatting tool
Apr 02, 2025 pm 09:03 PM
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.
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.
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.
