Hi yallz. Curses module its not the curse that you are thinking of. The curses module in Python is a library that provides functionalities for creating text-based user interfaces (TUIs) in a terminal environment. It allows you to control the cursor position, manipulate text attributes, and handle input events from the keyboard and mouse.
Here is a more detailed explanation of the key features and concepts associated with the curses module:
Initialization: To start using curses, you need to initialize it using the
curses.initscr()function. This function initializes the curses library and returns a special window object that represents the entire screen.
- Windows and Pads: In curses, a window is a rectangular region on the screen that can contain text or other graphical elements. You can create multiple windows within the main screen window. Additionally, pads are similar to windows but provide scrolling capabilities.
Text Output: To display text on the screen, you can use the
addstr(y, x, text)method of a window or pad object. This method adds the specified string of text at the given coordinates
(y, x)on the screen. You can also modify various text attributes such as colors, boldness, and underlining.
Input Handling: The
getch()method of a window or pad object is used to wait for keyboard input. It returns the ASCII value of the key pressed by the user. You can use this function to create interactive applications that respond to user input.
Screen Updates: The
refresh()method of a window or pad object updates the screen with any changes made to it. This is necessary to show the updated content to the user. You can also use the
doupdate()methods for more efficient screen updates.
- Key Codes: The curses module provides constants for special keys, such as function keys, arrow keys, and control characters. These constants can be used to handle specific key presses and create more sophisticated user interfaces.
It’s worth noting that the curses module is primarily designed for UNIX-based systems and may not work on all platforms. However, alternative libraries like
windows-curses can provide similar functionality on Windows.
