Python modules provide powerful building blocks for extending Python’s functionalityacross various programming domains. This list of Python modulescovers the core categories of Python modules, focusing onsystem
Instructions for building Python, from the README distributed with the source. Import Path¶ The search path for modules is managed as a Python list saved insys.path. The default contents of the path include the directory of the script used to start the application and the current working di...
Let’s talk a little bit about modules.Python模块是代码库,您可以使用import语句导入Python模块。 Python modules are libraries of code and you can import Python modules using the import statements. 让我们从一个简单的案例开始。 Let’s start with a simple case. 我们将通过说“导入数学”来导入数学模...
Instead, Python follows this convention: if the __init__.py file in the package directory contains a list named __all__, it is taken to be a list of modules that should be imported when the statement from <package_name> import * is encountered. For the present example, suppose you cr...
>>>importsys>>>sys.path.append('/ufs/guido/lib/python') 6.3. Thedir()Function The built-in functiondir()is used to find out which names a module defines. It returns a sorted list of strings: >>>importfibo,sys>>>dir(fibo)['__name__', 'fib', 'fib2']>>>dir(sys)['__display...
Python dir function The built-indirfunction gives a sorted list of strings containing the names defined by a module. dirfun.py #!/usr/bin/python """ This is dirfun module """ import math, sys version = 1.0 names = ["Paul", "Frank", "Jessica", "Thomas", "Katherine"] ...

Python 下一切皆对象,每个对象都有多个属性(attribute),Python对属性有一套统一的管理方案。与dir()的区别: dir() 是一个函数,返回的是list; __dict__是一个字典,键为属性名,值为属性值; dir()用来寻找一个对象的所有属性,包括__dict__中的属性,__dict__是dir()的子集; ...
List of modules The Feature Selection category includes these modules: Filter Based Feature Selection: Identifies the features in a dataset that have the greatest predictive power. Fisher Linear Discriminant Analysis: Identifies the linear combination of feature variables that can best group data into se...
