Method 1: Read the File Line by Line Using “file.readline()” Method To retrieve the file content line by line until the file ends, we use Python’s “file.readline()” method. This method takes the optionally specified size and retrieves the first line of the file. We can use this...

Any kind of parsing and analysis should happen asynchronously without delaying the file being saved. Could you please reopen this until Pylance doesn’t delay saving anymore? The issue described in the title here is not fixed: Saving .py files delayed by Getting code actions from ''Python' ...
content = file.read().decode('gbk') # 输出解码后的字符串到终端 print(content) ``` 这里的关键点在于: 1. 使用`open()`函数打开文件时,指定模式为`'rb'`(二进制读取模式),因为文件的实际内容是以字节形式存储的,尤其对于非ASCII编码(如GBK)的文本文件。 2. 在`open()`函数中通过`encoding='gbk'...
