PyQt5 – 色彩游戏

在本文中，我们将了解如何使用 PyQt5 创建彩色游戏。在这个游戏中，用户必须通过命名给定单词颜色的颜色名称来获得最高分，并且为了混淆玩家，文本将具有不同的颜色名称。下面是彩色游戏的样子

GUI Implementation Steps :
1. Create a head label to show the name of the game, set its features like alignment color etc.
2. Create a instruction label to tell the instruction to the user
3. Create a push button to start/ reset the game
4. Create Label to show the score
5. Create a line edit to get the input from user
6. Create a label for count down of 30 seconds

Back-end implementation steps :
1. Create start flag, a list of colors, counter value variable and score value variable
2. Create a timer object which call a method after one second
3. Inside the timer method check for the start flag if its true set counter value to the counter label and decrement the count value
4. Check if counter variable is equal to zero then make the start flag false and make the line edit disable
5. Add action to the start button
6. Inside the start button action make the start value to true set count value to 30 and clear the line edit text
7. Get the random choice from the color list and set that color to the color label
8. Again get the random choice from the list and set that text to the label
9. Add action to the line edit when enter is pressed
10. Inside the action of line edit check for the entered text with the random choice if matches increment the score value and change the color label color and text with another random value.
