Debugging Your Application

A. Setting breakpoints in PyCharm:

  • Click on the left-hand gutter of the code editor to set a breakpoint.
  • Run the application in debug mode by selecting "Debug (filename).py".

B. Stepping through the code:

  • Use the debugging toolbar to step through the code line by line.
  • Analyze variables and their values to identify and fix issues.

C. Inspecting variables and values:

  • While debugging, hover over variables to see their current values.
  • Use the "Watches" window to monitor specific variables throughout the debugging process.

Building and Distributing Your Application

A. Creating an executable file:

  • Install the PyInstaller package using pip.
  • Open a terminal within PyCharm and navigate to your project directory.
  • Run the command "pyinstaller --onefile (filename).py" to create an executable file.

B. Packaging the application for distribution:

  • Create a new folder and copy the executable file into it.
  • Include any necessary files or resources needed by your application.

C. Sharing the application with others:

  • Compress the folder containing the executable and resources into a ZIP file.
  • Distribute the ZIP file to others, along with instructions for running the application.
