ohhh, i'm invincible its only 2 steps.

 


Eureka!!!!!

python text to speech and this is awesome

pip install pyttsx3
pip install pypiwin32

the code:

import pyttsx3;
engine = pyttsx3.init();
engine.say("My wife is Sheryl and my two son's are Kiefer and Jairus");

sudo add-apt-repository ppa:jonathonf/python-3.6



I don't know my previous post above if its totally working on how to install python 3.6.
But here, I just tested it and obviously it works.

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6

Python libraries

Running API from python code needs this libraries.


installing in centos
curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
python get-pip.py

sudo pip install web.py
sudo pip install pyt
sudo pip install python-dateutil
sudo pip install tzlocal
sudo pip install pyyaml



installing in ubuntu, need to install the pip first.
$ sudo apt-get install python-pip python-dev build-essential
$ sudo pip install --upgrade pip
$ sudo pip install --upgrade virtualenv

How to send sms to your phone using python

The very basic how to create python program to send SMS to your phone.

Python Rocks!

I have a transfer knowledge today with my colleague as he will be leaving soon. While listening to him I look at his code on how to write the INI file in python. I was wondering how he did it. I know in Java before and I can't really remember the code. So to make it short, I google it and try to learn by my self.

I found this site and it's really straight forward.
https://martin-thoma.com/configuration-files-in-python/

you can create a variety not only INI file but also JSON,YAML and XML. wow, that's great!

My first sms project using TWILIO , PYTHON and DOCKER

I just found out this cool app called twilio and I really interested how it works. My main objective is to create a mass sms sending app but its too far at this point.

First, I found this youtube from cleverprogramming website. https://www.youtube.com/watch?v=uzBRycRYsqw. The tutorial is very straight forward. I can follow his steps but I want something different in my setup. I want to use docker instead installing in my development pc which I'm working in the office now. Hopefully no ones knows what I'm doing. haha

But anyway, so first I'm struggling how to mount the volume from my python image. So this is what I did.

1. run docker pull python
this will pull the latest images which i think python 3.6

2. create a dockerfile
FROM python
RUN pip install twilio
VOLUME ["/mnt/python_file"]

from script above, I creating a python base image and install twilio app and specify the volume. Isn't that easy. But the hardest part, is that I don't know if its working exactly what I wanted.

3. run docker build -t python-twilio

i have already my custom image, next will run this to create a container.

4. run docker run -v /c/Users/DEFAULT.DEFAULT-PC/volumes:/mnt/python_file python-twilio python /mnt/python_file/send_sms.py

previously, i didn't add '/mnt/python_files/' from send_sms.py which giving me error that the file is not found. So that's it, i received the sms message to my phone, Eureka!

btw, I have so much to improve my code. we will see next time to achieve my goal to build an app. Viola!



UPDATED:
The new command below is changing the volume from c: drive to d:.
d_drive name is the same which I configure in the Oracle VM virtualbox.

ex1:
docker run -v /d_drive/Lynard/development/personal/twilio_tutorial:/mnt/python_file twilio1 python /mnt/python_file/send_sms.py

ex2:
docker run -v /d_drive/Lynard/development/personal/twilio_tutorial:/mnt/codes ls/twilio python /mnt/codes/send_sms.py

So now, I can do and save my code in my drive D: isn't that great! Eureka!!!!

Remove the pycharm-*.tar.gz to save disk space (optional)
Run pycharm.sh from the bin subdirectory

NOTE: PyCharm on Linux doesn't need special installation or running any installation script. It runs out of the pycharm-*.tar.gz
