Cara menggunakan ta-lib python

Istilah utama¶

• pip adalah program penginstal yang disukai. Mulai dari Python 3.4, disertakan secara bawaan pada installer biner Python.

• Sebuah virtual environment adalah lingkungan Python semi-terisolasi yang memungkinkan paket diinstal untuk digunakan oleh aplikasi tertentu, dibandingkan diinstal sistem luas atau global.

• venv is the standard tool for creating virtual environments, and has been part of Python since Python 3.3. Starting with Python 3.4, it defaults to installing pip into all created virtual environments.

• virtualenv is a third party alternative [and predecessor] to venv. It allows virtual environments to be used on versions of Python prior to 3.4, which either don't provide venv at all, or aren't able to automatically install pip into created environments.

• The Python Package Index is a public repository of open source licensed packages made available for use by other Python users.

• the Python Packaging Authority is the group of developers and documentation authors responsible for the maintenance and evolution of the standard packaging tools and the associated metadata and file format standards. They maintain a variety of tools, documentation, and issue trackers on both GitHub and Bitbucket.

• distutils is the original build and distribution system first added to the Python standard library in 1998. While direct use of distutils is being phased out, it still laid the foundation for the current packaging and distribution infrastructure, and it not only remains part of the standard library, but its name lives on in other ways [such as the name of the mailing list used to coordinate Python packaging standards development].

Berubah pada versi 3.5: Penggunaan venv sekarang disarankan untuk membuat lingkungan virtual.

Penggunaan dasar¶

The standard packaging tools are all designed to be used from the command line.

The following command will install the latest version of a module and its dependencies from the Python Package Index:

python -m pip install SomePackage

Catatan

For POSIX users [including macOS and Linux users], the examples in this guide assume the use of a virtual environment.

For Windows users, the examples in this guide assume that the option to adjust the system PATH environment variable was selected when installing Python.

It's also possible to specify an exact or minimum version directly on the command line. When using comparator operators such as >,
