Python "Hello Web Bot"¶
This tutorial will guide you through the process of creating a simple Python web automation.
- BotCity Account
- BotCity Studio SDK
- Python 3.7 or higher
Downloading the WebDriver¶
To be able to work with web automations, we need to use the corresponding WebDriver to communicate with browsers for automation.
In doing so, it requires that the WebDriver for the chosen browser to be installed and available preferrably
PATH. If you can't add the necessary WebDriver to your
PATH you will be able to inform the
via code in your bot.
Here is a list of supported browsers along with links for you to download the proper WebDriver:
Please follow the instructions on the WebDriver website for installation and setup.
Once the desired WebDriver for the Web Browser to be used is installed we can proceed to the next steps.
Creating Your First Project¶
BotCity offers a template project which can be customized via a tool called cookiecutter.
In order to use it we need first to install the cookiecutter Python package by running the following command on your command-line terminal:
python -m pip install --upgrade cookiecutter
After doing that you are ready to create your first Python web automation using BotCity’s framework.
From Template to Project¶
With cookiecutter properly installed, it is time to make use of it and create a new project.
To create a new project using our template we will invoke the
cookiecutter and provide as argument the URL in which the templates from BotCity is located:
python -m cookiecutter https://github.com/botcity-dev/bot-python-template/archive/v2.zip
The system will prompt you with a couple of answers in order to properly create your project.
- Once prompted for project_type answer with
2for Web and press enter;
- For bot_id type
HelloWebBotand press enter;
After going through the process above you will now have a new folder named
Congratulations, you now have a project with BotCity’s Python Web Framework. 🏆
Let’s take a deeper look into it.
Exploring the Project¶
Under your project folder
HelloWebBot you will have the following structure:
HelloWebBot ├── bot.py <- Here is where you will develop your bot code. ├── resources <- Folder containing resources useful for the Bot. ├── build.bat <- Batch script to generate the package. ├── build.ps1 <- PowerShell script to generate the package. ├── build.sh <- Shell script to generate the package. ├── requirements.txt <- File describing the python dependencies for your Bot. └── HelloWebBot.botproj <- File used to load the project on BotStudio.
It may seem like a lot of files and folders but here are the most important ones:
- bot.py: Change this file and add here the code for your bot.
- resources: Add into this folder files to be used with your bot such as images, spreadsheets and etc.
- requirements.txt: Change this file and add all external dependencies that are used in the code.
All this information is great but it is time to see some action.

Setting WebDriver Path¶
As mentioned before, to be able to use the web framework features, it is necessary to configure the WebDriver path of the browser we are using.
If you don't have the WebDriver path added to your
PATH, you can manually add the path in your bot code, via the
... def main(): bot = WebBot() # Configure whether or not to run on headless mode bot.headless = False # Changing the default Browser to Firefox bot.browser = Browser.FIREFOX # Setting the path of the Firefox WebDriver bot.driver_path = "<path to your WebDriver binary>" ...
Chrome is set as the default browser. To change the default browser, just select another option through the
Testing Your Project Locally¶
To test your project locally, let's first install the Python dependencies that are being used in the project.
Using the command-line tool, access the
HelloWebBot folder which we described above.
Installing the Project¶
From this folder, run the command below to install the dependencies defined in the
pip install --upgrade -r requirements.txt
This command will produce a lot of output which means that all dependencies such as
botcity-framework-web, and others are being installed.
Once this process is complete, your project is ready to run.
Running the Bot¶
Our template project runs a very simple automation. It opens up the web browser you have configured and loads BotCity’s website.
Using the open terminal inside the project folder, you can run your
HelloWebBot automation with the following command:
