Steps to Build the Python Project on Typing Speed TestImport the libraries. For this project based on Python, we are using the pygame library. Create the game class. Now we create the game class which will involve many functions responsible for starting the game, reset the game and few helper functions to perform draw_text () method. The draw_text () method of Game class is a helper function that will draw the text on the screen. get_sentence () method. Remember that we have a list of sentences in our sentences.txt file? show_results () method. The show_results () method is where we calculate the speed of the users typing. run () method. This is the main method of our class that will handle all the events. reset_game () method. The reset_game () method resets all variables so that we can start testing our typing speed again.
Python print() function prints the message to the screen or any other standard output device. Syntax: print(value(s), sep= , end = n, file=file, flush=flush) Parameters: value(s) : Any value, and as many as you like.
