PyQt5 – 火焰计算器
在本文中，我们将了解如何使用 PyQt5 创建火焰计算器。这个火焰计算器基于两个给定名称的算法评估和预测关系的结果。
火焰是一个流行的游戏，以首字母缩写命名：朋友，恋人，深情，婚姻，敌人，兄弟姐妹。该游戏无法准确预测某个人是否适合您，但与您的朋友一起玩会很有趣。

GUI implementation steps :
1. Create a label that says enter player 1 name and set color and geometry to it
2. Add QLineEdit widget in front of the first name label to get the first name
3. Similarly create another label that says enter player 2 name and set color and geometry to it
4. Add QLineEdit widget in front of this label to get the second name
5. Create a label to show the result and set its border, geometry and change its font.
6. Create a push button at the bottom which says get result.
Back end implementation steps :
1. Add action to the push button
2. Inside the push button action get both player names
3. Remove the spacing in between the names
4. Call the get result method that returns the result
5. Inside the get result method call the remove letter method that removes the common characters with their respective common occurrences.
6. Then get the count of characters that are left and take FLAMES letters as [“F”, “L”, “A”, “M”, “E”, “S”]
7. Start removing letter using the count we got. The letter which last the process is the result, return the result
8. Set the result to the label using setText method.
