  Microsoft provides different learning topics for you to get learning about
  Python, these topics are not too long and cover basic knowledge about Python
  to using Python with ML. These are very hands-on and if you happen to finish
  everything should be able to help you get to learn Python a lot in different
  areas.&nbsp;

I'm an experienced developer with C# and Javascript but haven't done any work with Python yet, my main motivation for learningPython is part of learning AL, ML lots of courses require you to have basic Python knowledge. So as a beginner who starts learningPython, I'm searching around to see where are good resources to learn and will share at here as well.

How to Get Start with Python


<h2>How to generate Pokemon Proto API to Csharp Type</h2>
<p>
  Pokemon API use
  <a
    href="https://developers.google.com/protocol-buffers/"
    target="_blank"
    rel="noopener"
    >Google Protocol Buffers</a
  >
  to generate API contract to C#. This blog will demo how to do that. Following
  demo we'll use Protobuf's 3.0.0-beta-2 for csharp., you can download from
  following link,
  <a
    href="https://github.com/google/protobuf/releases"
    target="_blank"
    rel="noopener"
    >Protobuf release</a
  >. Also, we'll need Python, because
  <a
    href="https://github.com/AeonLucid/POGOProtos/tree/v1.0"
    target="_blank"
    rel="noopener"
    >POGOProtos</a
  >
  need Python to run command to generate Protos to Csharp.
</p>
<ul>
  <li>
    <a
      href="https://github.com/google/protobuf/releases"
      target="_blank"
      rel="noopener"
      >Protobuf Release</a
    >
  </li>
  <ul>
    <li>Download google's protobuf for your enviroment.</li>
    <li>
      You can click following link to download or go to above link to check the
      latest version.
    </li>
    <li>
      <a
        href="https://github.com/google/protobuf/releases/download/v3.0.0-beta-2/protoc-3.0.0-beta-2-win32.zip"

      rel="noopener"
      >POGOProtos</a
    >
  </li>
  <ul>
    <li>
      Github repo contains ProtoBuf, the .proto files need to decode PokemonGo
      RPC api.
    </li>
  </ul>
  <li>
    <a
      href="https://wiki.python.org/moin/BeginnersGuide/Download"
      target="_blank"
      rel="noopener"
      >Python Download</a
    >
  </li>
  <ul>
    <li>POGOProtos need Python to run for generate Csharp type.</li>
  </ul>
</ul>
<h3>1. Download Google Protobuff</h3>
<p>
  At this blog, I'm using the 3.0.0-beta-2 with my windows 10, once you download
  this to your pc, you'll also need to add path to Enviroment Variables.
</p>
<p>
  <img
    class="img-responsive"
    src="https://d1p0mp3f1fx0hz.cloudfront.net/_n3fvwf6wy.png"
    alt=""
  />
</p>
<h3>Add path to System Enviroment Variables</h3>
<p>
  Once you add the path, you can type <code>protoc</code> at command line tools.
</p>
<pre class="language-xml"><code>A:\protoc-3.0.0-win32\bin
</code></pre>
<p>Following is example command line to get version of he protoc</p>
<pre class="language-xml"><code>&gt; protoc --version
</code></pre>
<h3>2. Download Python</h3>
<p>
  You'll need Python, so go to
  <a
    href="https://wiki.python.org/moin/BeginnersGuide/Download"
    target="_blank"
    rel="noopener"
    >this website</a
  >
  to get the Python, once you download the Python, try not to change their
  default folder, add also add the path to the system Vnviroment Variables as
  well.
</p>
<pre class="language-xml"><code>C:\Python27
C:\Python27\Scripts</code></pre>
<h3>3. Compile all the PokemonGO Api Protos</h3>
<p>
  Once you get the <code>Protos</code> and <code>Python</code>, you can start to
  get what's you really want, which is the PokemonGo Protos to call Pokemon API.
  Go to this
  <a
    href="https://github.com/AeonLucid/POGOProtos/tree/v1.0"
    target="_blank"
    rel="noopener"
    >Github Repo to get latest souce code</a
  >.
</p>
<p>
  You have couple of choice to compile Protos to Csharp here, I'm using
  following command to compile all protos to csharp classes, you will move
  location to the place contains the <code>compile.py</code>, then run following
  command line.
</p>
<pre class="language-xml"><code>python compile.py
</code></pre>
<h3>Output result of csharp classes</h3>
<p>
  After run the command line, you'll get all the csharp classes as following at
  out folder.
</p>
