在python项目中,需要批量ocr图片后,批量生成同名的txt文件,存储文件需要使用路径,一般是path =r'd:\folder\filename.txt',使用变量怎么代替路径呢?

步骤如下:
直接使用变量就可以了。
path=variable
因为r'()'符号的作用是使用原始字符串,它会改变引号内字符转义的规则。如果您只是从另一个变量中获取值,则不需要r写入字符串。
代码:
filelist=['test1.jpg','test2.jpg'] for filename in filelist: filenamev= 'D:\\baoan-nlt\\' + filename savepath = filenamev[:-4]+'.txt'

Mathematical operations of the entire array in NumPy can be efficiently implemented through vectorized operations. 1) Use simple operators such as addition (arr 2) to perform operations on arrays. 2) NumPy uses the underlying C language library, which improves the computing speed. 3) You can perform complex operations such as multiplication, division, and exponents. 4) Pay attention to broadcast operations to ensure that the array shape is compatible. 5) Using NumPy functions such as np.sum() can significantly improve performance.

In Python, there are two main methods for inserting elements into a list: 1) Using the insert(index, value) method, you can insert elements at the specified index, but inserting at the beginning of a large list is inefficient; 2) Using the append(value) method, add elements at the end of the list, which is highly efficient. For large lists, it is recommended to use append() or consider using deque or NumPy arrays to optimize performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
