Color game using Tkinter in Python



TKinter is widely used for developing GUI applications. Along with applications, we can also use Tkinter GUI to develop games. Let’s try to make a game using Tkinter. In this game player has to enter color of the word that appears on the screen and hence the score increases by one, the total time to play this game is 30 seconds. Colors used in this game are Red, Blue, Green, Pink, Black, Yellow, Orange, White, Purple and Brown. Interface will display name of different colors in different colors. Player has to identify the color and enter the correct color name to win the game. Below are the steps of above game :


# import the modules  
import tkinter 
import random 

# list of possible colour. 
colours = ['Red','Blue','Green','Pink','Black', 
         'Yellow','Orange','White','Purple','Brown'] 
 score = 0

# the game time left, initially 30 seconds. 
timeleft = 30

# start the countdown timer. 
def startGame(event):
    if timeleft == 30: 

       # start the countdown timer. 
       countdown() 

   # run the function to 
   # choose the next colour. 
   nextColour()

# Function to choose and 
# display the next colour. 
def nextColour(): 

  # use the globally declared 'score' 
  # and 'play' variables above. 
  global score 
  global timeleft 

  # if a game is currently in play 
  if timeleft > 0: 

     # make the text entry box active. 
     e.focus_set() 

    # if the colour typed is equal 
    # to the colour of the text 
    if e.get().lower() == colours[1].lower(): 
      score += 1

    # clear the text entry box. 
    e.delete(0, tkinter.END) 

    random.shuffle(colours) 

    # change the colour to type, by changing the 
    # text _and_ the colour to a random colour value 
    label.config(fg = str(colours[1]), text = str(colours[2]))
 
    # update the score. 
    scoreLabel.config(text = "Score: " + str(score)) 

# Countdown timer function 
def countdown(): 

    global timeleft 

    # if a game is in play 
    if timeleft > 0: 

        # decrement the timer. 
        timeleft -= 1

        # update the time left label 
        timeLabel.config(text = "Time left: "
                               + str(timeleft)) 

        # run the function again after 1 second. 
        timeLabel.after(1000, countdown) 

# Driver Code 

# create a GUI window 
root = tkinter.Tk() 

# set the title 
root.title("COLORGAME")

# set the size 
root.geometry("375x200")

# add an instructions label 
instructions = tkinter.Label(root, text="Type in the colour"       "of the words, and not the word text!", 
                             font = ('Helvetica', 12)) 
instructions.pack()

# add a score label 
scoreLabel = tkinter.Label(root, text = "Press enter to start",                      font = ('Helvetica', 12)) 
scoreLabel.pack()

# add a time left label
timeLabel = tkinter.Label(root, text = "Time left: " +
              str(timeleft), font = ('Helvetica', 12)) 
timeLabel.pack()

# add a label for displaying the colours 
label = tkinter.Label(root, font = ('Helvetica', 60)) 
label.pack() 

# add a text entry box for 
# typing in colours 
e = tkinter.Entry(root)

# run the 'startGame' function  
# when the enter key is pressed
root.bind('', startGame)
e.pack() 

# set focus on the entry box
e.focus_set()

# start the GUI 
root.mainloop()
