The -m tells Python to load it as a module, not as the top-level script.Or perhaps you don't actually want to run moduleX, you just want to run some other script, say myfile.py, that uses functions inside moduleX. If that is the case, put myfile.py somewhere else – not ...
import绝对是我们在使用python时最常用的语句之一了,但其实关于import,需要注意的地方还真不少,如导入第三方库,导入自己写的库,导入相对路径下文件中的方法,在包内部的相对与绝对导入等导入源;有导入的顺序;有Lazy Load惰性导入方法;有已经导入后的重载等等。本文就旨在讲清楚这些问题,并提供足够的示例以供参考。 I...

math is part of Python’s standard library, which means that it’s always available to import when you’re running Python. Note that you write math.pi and not just simply pi. In addition to being a module, math acts as a namespace that keeps all the attributes of the module together....
