Python3 Environmental build

In this chapter we will show you how to build a Python3 development environment locally.

Python3 can be applied to multiple platforms including Windows, Linux and Mac OS X.

  • Unix (Solaris, Linux, FreeBSD, AIX, HP/UX, SunOS, IRIX, etc.)
  • Win 9x/NT/2000
  • Macintosh (Intel, PPC, 68K)
  • OS/2
  • DOS (various DOS versions)
  • PalmOS
  • Nokia portable phone
  • Windows CE
  • Acorn/RISC OS
  • BeOS
  • Amiga
  • VMS/OpenVMS
  • QNX
  • VxWorks
  • Psion
  • Python can likewise be ported to Java and .NET virtual machines.


Python3 Download

Python3's latest source code, binary documentation, news, etc. can be viewed on Python's official website:

Python official site: https://www.python.org/

>

You can download Python's documentation at the following link, and you can download documents in formats such as HTML, PDF, and PostScript.

Python documentation download address: https://www.python.org/doc/



Python installation

Python has been ported to many platforms (it has been modified to work on different platforms).

You need to download the binary code for your platform and install Python.

If your platform's binary code is not available, you will need to manually compile the source code using the C compiler.

The compiled source code is more functionally selective and provides more flexibility for Python installations.

Source Code is accessible for establishment on Linux.

Here are the approaches to introduce Python3 on various stages.

Unix & Linux Platform Installation Python3:

Here's how to install Python3 on different platforms.

  • Open an internet browser to get to https://www.python.org/downloads/source/
  • Select a source tarball for Unix/Linux.
  • Download and unfasten the compress record Python-3.x.x.tgz, 3.x.x for the relating variant number you downloaded.
  • If you have to redo a few choices to adjust Modules/Setup

Use the Python 3.6.1 version as an example:

# tar -zxvf Python-3.6.1.tgz
# cd Python-3.6.1
# ./configure
# make && make install

Check if Python3 is available:

# python3 -V
Python 3.6 .1

Window stage establishment Python:

Here are the basic strides to introduce Python on the Window stage.

Open the internet browser to get to https://www.python.org/downloads/windows/ , by and large download executable installer, x86 implies 32-bit machine, x86-64 implies 64-bit machine.

MAC Platform Installation Python:

The MAC framework accompanies a Python 2.7 condition, you can interface Download the most recent form of Python 3.x at https://www.python.org/downloads/macintosh osx/.

You can likewise introduce it by alluding to the manner in which the source is introduced.



Environment Variable Configuration

Programs and executables can be in many directories, and these paths are most likely not in the search path where the operating system provides executable files.

The path is stored in an environment variable, which is a named string maintained by the operating system. These variables contain information about the available command line interpreters and other programs.

The path variable in Unix or Windows is PATH (UNIX is case sensitive and Windows is not case sensitive).

In Mac OS, the python installation path was changed during the installer process. If you need to reference Python in other directories, you must add the Python directory to the path.

Set environment variables on Unix/Linux

Python condition variable

The following essential condition factors apply to Python:

Variable NameDescription
PYTHONPATH PYTHONPATH is the Python seek way. As a matter of course, the modules we import will be looked from PYTHONPATH.
PYTHONSTARTUP After Python begins, search for the PYTHONSTARTUP condition variable and afterward execute the code in the document indicated by this variable.
PYTHONCASEOK Adding PYTHONCASEOK condition factors will put forth python import defense insensitive.
PYTHONHOME Another module seek way. It is normally implanted in the PYTHONSTARTUP or PYTHONPATH registry, making it simpler to switch between the two module libraries.


Run Python

There are three different ways to run Python:

1, intuitive mediator:

You can go to python through the direction line window and begin composing Python code in the intuitive translator.

You can do python encoding on Unix, DOS or whatever other framework that gives a direction line or shell.

$ python # Unix/Linux

Or then again

C:>python # Windows/DOS

Add a Python directory to the environment variable:

OptionsDescription
-dShow troubleshoot data when parsing
-OGenerate improved code ( .pyo document )
-SDo not acquaint an area with discover the Python way at startup
-VOutput Python rendition number
-X Worked in special cases (just for strings) since variant 1.6 are out of date.
-c cmd Execute the Python content and run the outcome as a cmd string.
file Execute a python content in a given python document.

Run Python3 program in Cloud Studio

The 3.0 variant of Python, frequently alluded to as Python3000, or Py3k for short. This is a bigger update than the past variant of Python. All together not to present an excess of unwieldy, Python 3.0 was not intended to be in reverse good. Numerous projects intended for before renditions of Python are not working legitimately on Python 3.0. The Python advancement condition that Cloud Studio accommodates us is the Python adaptation 2.7. The accompanying advances will enable you to run a program written in Python3 on Cloud Studio

  • step1: Sign in to Tencent Cloud Developer Platform, select PHP + Python + Java advancement condition, as of now, I see the terminal info direction python - version can see that the right now utilized python mediator rendition is 2.7.12

  • step2: Install Python3, execute the order, introduce Python3 and check whether the translator works.
sudo apt-get introduce python3
