Using Flask and Flask-WTF to build websites in Python 2.7 and 3.6.2 - part 002.

This is one update of my old tutorial about Flask and python 2.7 under Linux from here.
The default install of python 2.7 and pip is very simple - read this tutorial.
First, you need to install the Flask python module under Windows 10:

C:\Python27\Scripts>pip install Flask

The simple example of the running Flask python module is one script named hello.py:

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":
    app.run()

Using the command to run the script and show the result into your browser:

C:\Python27>python.exe hello.py
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Now the installation of Flask-WTF python module:

C:\Python27\Scripts>pip install Flask-WTF
Collecting Flask-WTF
  Downloading Flask_WTF-0.14.2-py2.py3-none-any.whl
Collecting WTForms (from Flask-WTF)
  Downloading WTForms-2.1.zip (553kB)

Now I try with Python 3.6.2 with both python modules and works great.

C:\Python362\Scripts>pip3.6.exe install flask
...

operable program or batch file.

The gtts python module.

This python module named gtts will create an mp3 file from spoken text via the Google TTS (Text-to-Speech) API.
The installation of the gtts python module under Windows 10.

C:\Python27\Scripts>pip install gtts
Collecting gtts
  Downloading gTTS-1.2.0.tar.gz
Requirement already satisfied: six in c:\python27\lib\site-packages (from gtts)
Requirement already satisfied: requests in c:\python27\lib\site-packages (from gtts)
Collecting gtts_token (from gtts)
  Downloading gTTS-token-1.1.1.zip
Requirement already satisfied: chardet<3 .1.0="">=3.0.2 in c:\python27\lib\site-packages (from requests->gtts)

Requirement already satisfied: idna<2 .6="">=2.5 in c:\python27\lib\site-packages (from requests->gtts)
Collecting urllib3<1 .22="">=1.21.1 (from requests->gtts)
  Using cached urllib3-1.21.1-py2.py3-none-any.whl
Installing collected packages: gtts-token, gtts, urllib3
  Running setup.py install for gtts-token ... done
  Running setup.py install for gtts ... done
  Found existing installation: urllib3 1.22
    Uninstalling urllib3-1.22:
      Successfully uninstalled urllib3-1.22
Successfully installed gtts-1.2.0 gtts-token-1.1.1 urllib3-1.21.1

Let's see a basic example:

from gtts import gTTS
import os
import pygame.mixer
from time import sleep
 
user_text=input("Type your text: ")
 
translate=gTTS(text=user_text ,lang='en')
translate.save('output.wav')

pygame.mixer.init()
path_name=os.path.realpath('output.wav')
real_path=path_name.replace('\\','\\\\')
pygame.mixer.music.load(open(real_path,"rb"))
pygame.mixer.music.play()
while pygame.mixer.music.get_busy():
    sleep(1)

The text will be taken by input into a user_text variable.
You need to type the text into quotes also you will get an error.
The result will be one audio file named output.wav and play it by pygame python module.
This uses the default voices for all languages. I don't find a way to change this voices with python.
