Use Relative Import Syntax:Relative imports allow you to specify the path to the module relative to the current file's location. Use the.(dot) to represent the current directory and..(dot dot) to represent the parent directory. For example, if you have a module namedutils.pyin the parent ...
# 直接运行search.py可以导入成功 # run.py中可以成功 # python run.py from src.postprocessors.verifiers.search import SearchVerifier # run.py文件中 or 直接从根目录开始应用 # search.py里 from src.llms.qwen_ds import QwenModel 4. 类似3 # qwen_ds.py ROOT = Path(__file__).absolute()....
这种方法适用于将目录组织为Python包。在文件所在目录下新建一个空的__init__.py文件，这样Python解释器就会将该目录视为一个包。然后，可以使用from application.app.folder.file import func_name这样的语句来导入包中的类或函数。__init__.py文件还可以用来导入包中的其他模块，从而在包级别直接引用...

Return sends a specified value back to its caller whereas Yield can produce a sequence of values. We should use yield when we want to iterate over a sequence, but don't want to store the entire sequence in memory. import sys # for example when reading a large file, we only care about...

This does not introduce the module name from which the imports are taken in the local symbol table (so in the example,fibois not defined). 这种导入方式不会将模块名字fibo放入到当前模块的符号表中(例如,输入fibo是未定义的)。 There is even a variant to import all names that a module defines...
