Python: Output flickers in Terminal
Output flickering in the terminal can be caused by various reasons, such as a high volume of output, delays in processing, or issues with the terminal itself.
One possible solution is to use the curses
library in Python to create a more controlled output display. curses
is a library for creating terminal UIs that allows you to manipulate the cursor, change the color of text, and more.
Here is an example of using curses
to print text to the terminal without flickering:
pythonimport curses
def main(stdscr):
# Clear the screen
stdscr.clear()
# Print a message
stdscr.addstr("Hello, world!")
# Refresh the screen to show the output
stdscr.refresh()
# Wait for user input
stdscr.getkey()
if __name__ == '__main__':
# Initialize curses
curses.wrapper(main)
In this example, the curses.wrapper()
function takes care of initializing and cleaning up the curses
library, and the stdscr
object represents the terminal screen. The addstr()
method is used to print text to the screen, and the refresh()
method is called to update the display.
Another option is to try using a different terminal emulator that may have better performance or compatibility with your system. Some popular options include gnome-terminal
, konsole
, and xterm
.
