我们可以将父目录所在的文件夹添加到sys.path中,然后就可以直接导入其中的文件了。 importsys sys.path.append('/path/to/parent/directory')frommoduleimportMyClass 1. 2. 3. 4. 在上面的例子中,我们将父目录所在的文件夹添加到sys.path中,然后就可以导入该文件夹中的module模块并使用其中定义的MyClass类。
Import the Target Module:Once the parent directory is added to thesys.path, you can import the module using the standard import statement: from utils import some_function This import statement is the same as the relative import example, but it works because the parent directory is now included...
from module_name import logger as logger_a ---> 为导入的变量或方法取个别名,引用时直接用别名 1.同级目录下模块的导入: 在main_day41.py中导入para_day41.py,两种方法: #方法一: 相当于把para_day41.py中的所有代码拷贝过来赋值给变量para_day41,引用时直接用"该变量." import para_day41 para_d...
from multiprocessing.pool import Pool 使用绝对导入方式也会导致一些问题,当我们导入本地目录的模块时,Python经常会找不到相应的库文件而抛出ImportError异常。解决这样的问题最为简单的是将本地目录添加到sys.path列表中去,在pycharm中可以对文件夹右键选择Mark Directory as->Sources Root。
