PyQt5 – 拼字游戏

在本文中，我们将了解如何使用 PyQt5 创建一个混乱的文字游戏。乱字游戏：给玩家乱字，玩家必须重新排列单词的字符才能做出正确有意义的单词。下面是游戏的样子

GUI implementation steps : 
1. Create a heading label that display the game name 
2. Create label that shows the jumbled word 
3. A line edit widget that get the text 
4. A push button that check the input text which is beside the line edit 
5. Create a result label that tells if answer is correct or not and change its color 
6. Two push button to start and reset the game
Back end implementation steps : 
1. Create a list of words 
2. Add action to the check button 
3. Inside the action of check push button get the input text and compare it with the input word 
4. If word matches show result as correct and set color to green else set color to red and say wrong 
5. Add action to the start button 
5. Inside the start button action get the current word from the list using random function 
6. Create a jumble word from the current word and set it to the jumble label 
7. Remove the text of the result label and set color to yellow 
8. Add action to the reset button 
9. Inside the reset button action set the current word to blank 
10. Remove text from all labels and set their color back to original one
