在Python IDLE中执行sys.path,sys.path中第一个路径通常为空,代表执行文件所在的路径,所以在被导入模块与执行文件在同一目录下时肯定是可以正常导入的,而针对被导入的模块与执行文件在不同路径下的情况,为了确保模块对应的源文件仍可以被找到,需要将源文件所在的路径添加到sys.path中,假设foo.py所在的路径为/
列表中每一个元素都可以当做一个目录来看:在列表中会发现有.zip或.egg结尾的文件,二者是不同形式的压缩文件,事实上Python确实支持从一个压缩文件中导入模块,只需把他们当成目录看即可. 在Python IDLE中执行sys.path,sys.path中第一个路径通常为空,代表执行文件所在的路径,所以在被导入模块与执行文件在同一目录下...
This is an environment variable that returns search path for all Python modules. >>> sys.path ['', 'C:\\python37\\Lib\\idlelib', 'C:\\python37\\python36.zip', 'C:\\python37\\DLLs', 'C:\\python37\\lib', 'C:\\python37', 'C:\\Users\\acer\\AppData\\Roaming\\Python\\Pyt...
print("Bye", name) return The module above contains two simple function that will print the supplied name, along with the greeting. If you follow along, make sure to save the module in the same directory that will also contain the top-level file. There are two ways to import a module:...
The resulting search path is accessible in the Python variable sys.path, which is obtained from a module named sys:Python >>> import sys >>> sys.path ['', 'C:\\Users\\john\\Documents\\Python\\doc', 'C:\\Python36\\Lib\\idlelib', 'C:\\Python36\\python36.zip', 'C:\\Python...
As the Python interpreter starts, it put all the above locations in a list returned by the sys.path attribute. Example: Module Attributes Copy import sys sys.path ['','C:\python36\Lib\idlelib', 'C:\python36\python36.zip', 'C:\python36\DLLs', 'C:\python36\lib', 'C:\python36'...

Take another look at the function as it currently stands. Pay particular attention to the three strings in this code, which are all colored green by IDLE: Understanding the string quote characters In Python, strings can be enclosed in a single quote character ('), a double quote character (...
This is because sys.modules.clear removes IDLE from memory, so you will have to use the second solution in that case. On the first run, the solution determines which modules are initial modules for the system (all those that are loaded at this point). On all other runs, the solution ...
This video course is part of the Python Basics series, which accompanies Python Basics: A Practical Introduction to Python 3. You can also check out the other Python Basics courses. Note that you’ll be using IDLE to interact with Python throughout this course. If you’re just getting sta...
