Pyhton 中的数字转换

Question

我正在制作一个计算器，我想添加数字转换的功能，但它似乎不起作用。这就是我的目标：当我单击 BIN 按钮（或任何数字转换按钮）时，它会将其键入，然后我键入二进制数字，然后单击任何其他数字转换。按钮，例如 DEC，它会输入它，当我按下等号按钮时，它应该给我十进制的二进制数，但事实并非如此。我将不胜感激任何帮助。谢谢。

这是我的代码：

我希望它打印出例如“BIN 111 DEC”并给我 111 的十进制数。

Answer 1

请按照以下步骤操作：

创建一个变量来存储当前输入值，初始化为空字符串。
创建一个变量来存储当前的数制（例如“BIN”、“DEC”等），初始化为None。
当点击数字转换按钮（例如“BIN”、“DEC”）时，相应地更新当前的数字系统变量。
当点击数字按钮（0-9）时，将点击的数字追加到当前输入值变量中。
点击等于按钮时，根据当前数制进行数字转换。
如果当前数制为“BIN”，则将输入值从二进制转换为十进制。
如果当前数制为“DEC”，则将输入值从十进制转换为二进制。
使用转换后的值更新显示。

当前输入=“” 当前_编号_系统 = 无

def handle_number_conversion(number_system): 全局当前号码系统当前系统编号 = 系统编号 # 更新显示或执行任何必要的操作

def handle_number_click(number): 全局电流输入当前输入 += str(数字) # 更新显示或执行任何必要的操作

defhandle_equal_click(): 全局当前输入、当前数字系统如果当前编号系统==“BIN”：小数值 = int(当前输入, 2) 打印（“BIN”，当前输入，“DEC”，十进制值） # 更新显示或执行任何必要的操作 elif current_number_system == "DEC": 二进制值 = bin(int(当前输入))[2:] 打印（“DEC”，当前输入，“BIN”，二进制值） # 更新显示或执行任何必要的操作

使用示例

handle_number_conversion("BIN") # 用户点击BIN按钮 handle_number_click(1) # 用户点击数字1 handle_number_click(1) # 用户点击数字1 handle_number_click(1) # 用户点击数字1 handle_number_conversion("DEC") # 用户点击DEC按钮 handle_equal_click() # 用户点击等于按钮
