Use the file.read(1) method to read the file character by character in a while loop. Use a break statement to exit the loop at the end of the file. main.py with open('example.txt', 'r', encoding='utf-8') as file
本文提出的多模态RAG方法采用模态特定处理、后期融合和关系保留的技术架构,在性能表现、准确性指标和实现复杂度之间实现了最佳平衡。
python缩进来表示代码块,不使用大括号 {} 。 缩进的空格数是可变的,但是同一个代码块的语句必须包含相同的缩进空格数。 4、数字(Number)类型 python中数字有四种类型:整数、布尔型、浮点数和复数。 int(整数), 如 1 bool(布尔), 如 True float(浮点数), 如 1.23、3E-2 complex(复数), 如 1 + 2j、 ...

Python-tesseract is an optical character recognition (OCR) tool for python. That is, it will recognize and "read" the text embedded in images. Python-tesseract is a wrapper for Google’s Tesseract-OCR Engine. It is also useful as a stand-alone invocation script to tesseract, as it can re...
In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...
