用python编写个简单的进制转换器

这个案例将显示十进制到二进制的转换过程。程序将要求输入一个十进制数，然后当点击“Click_Me”按钮时，它将被转换成二进制。十进制数将由八位二进制数表示，二进制数的每一位都将放在一个文本字段中。

下面是制作此应用程序的步骤：

创建py项目

 创建窗口

# 创建窗口
win =tk.Tk()
# 设置标题
win.title("进制转换器1.1")

# 设置窗口大小
win.geometry("800x200")

创建Label标签，设为标题

# 设置项目标题标签
title = tk.Label(win, text="DECIMAL TO BINARY CONVERSION \n--------------------------------------------------")
title.grid(row=0, column=1)

创建输入框标签，和转换后单独的标签

# 输入框标签
t1 = tk.Label(win, text="Insert The Number")
t1.grid(row=1, column=0)

创建输入框Text ，用来输入转换之前的数字

# 设置下方单位
Lb7 = tk.Label(win,text="bit7")
Lb7.grid(row=3,column=2)

b6 = tk.Text(win,bd=5,width=5,height=3)
b6.grid(row=2,column=3,sticky=W)
Lb6 = tk.Label(win,text="bit6")
Lb6.grid(row=3,column=3)

b5 = tk.Text(win,bd=5,width=5,height=3)
b5.grid(row=2,column=4,sticky=W)
Lb5 = tk.Label(win,text="bit5")
Lb5.grid(row=3,column=4)

b4 = tk.Text(win,bd=5,width=5,height=3)
b4.grid(row=2,column=5,sticky=W)
Lb4 = tk.Label(win,text="bit4")
Lb4.grid(row=3,column=5)

b3 = tk.Text(win,bd=5,width=5,height=3)
b3.grid(row=2,column=6,sticky=W)
Lb3 = tk.Label(win,text="bit3")
Lb3.grid(row=3,column=6)

b2 = tk.Text(win,bd=5,width=5,height=3)
b2.grid(row=2,column=7,sticky=W)
Lb2 = tk.Label(win,text="bit2")
Lb2.grid(row=3,column=7)

b1 = tk.Text(win,bd=5,width=5,height=3)
b1.grid(row=2,column=8,sticky=W)
Lb1 = tk.Label(win,text="bit1")
Lb1.grid(row=3,column=8)

b0 = tk.Text(win,bd=5,width=5,height=3)
b0.grid(row=2,column=9,sticky=W)
Lb0 = tk.Label(win,text="bit0")
Lb0.grid(row=3,column=9)

创建转换后的单独显示框

# 设置二进制每位的显示框
b7 = tk.Text(win,bd=5,width=5,height=3)
b7.grid(row=2,column=2,sticky=W)

定义函数，实现获取输入框数字，转换二进制，输出功能

def Click_Me():
    """计算十进制转二进制"""
    n = str(bin(int(text.get())))  # 从text中获取十进制数，转为整型，使用bin方法转为二进制
    m = n.replace("0b", "")  # 删除转为二进制留下的”0b“
    if len(m) <= 8:
        """判断长度，不够8位在前面添加相应的0"""
    m = (8 - len(m)) * "0" + m
    b7.insert(END, m[0])  # 取出字符串的第一位，下标为0的数，显示到第一个文本框中
    b6.insert(END, m[1])
    b5.insert(END, m[2])
    b4.insert(END, m[3])
    b3.insert(END, m[4])
    b2.insert(END, m[5])
    b1.insert(END, m[6])
    b0.insert(END, m[7])

定义按钮，添加函数

# 按钮
butt = tk.Button(win, text="Click Me", command=Click_Me)
butt.grid(row=2, column=1, sticky=W)

全部代码如下：

# 导入模块
import tkinter as tk
from tkinter import*

# 创建窗口
win =tk.Tk()
# 设置标题
win.title("进制转换器1.1")

# 设置窗口大小
win.geometry("800x200")

# 设置点击事件
def Click_Me():
    """计算十进制转二进制"""
    n = str(bin(int(text.get())))  # 从text中获取十进制数，转为整型，使用bin方法转为二进制
    m = n.replace("0b", "")  # 删除转为二进制留下的”0b“
    if len(m) <= 8:
        """判断长度，不够8位在前面添加相应的0"""
    m = (8 - len(m)) * "0" + m
    b7.insert(END, m[0])  # 取出字符串的第一位，下标为0的数，显示到第一个文本框中
    b6.insert(END, m[1])
    b5.insert(END, m[2])
    b4.insert(END, m[3])
    b3.insert(END, m[4])
    b2.insert(END, m[5])
    b1.insert(END, m[6])
    b0.insert(END, m[7])

# 设置项目标题标签
title = tk.Label(win, text="DECIMAL TO BINARY CONVERSION \n--------------------------------------------------")
title.grid(row=0, column=1)

# 输入框标签
t1 = tk.Label(win, text="Insert The Number")
t1.grid(row=1, column=0)

# 输入框
text = tk.Entry(win, bd=5, width=15)
text.grid(row=2, column=0, sticky=W)

# 按钮
butt = tk.Button(win, text="Click Me", command=Click_Me)
butt.grid(row=2, column=1, sticky=W)

# 设置二进制每位的显示框
b7 = tk.Text(win,bd=5,width=5,height=3)
b7.grid(row=2,column=2,sticky=W)

# 设置下方单位
Lb7 = tk.Label(win,text="bit7")
Lb7.grid(row=3,column=2)

b6 = tk.Text(win,bd=5,width=5,height=3)
b6.grid(row=2,column=3,sticky=W)
Lb6 = tk.Label(win,text="bit6")
Lb6.grid(row=3,column=3)

b5 = tk.Text(win,bd=5,width=5,height=3)
b5.grid(row=2,column=4,sticky=W)
Lb5 = tk.Label(win,text="bit5")
Lb5.grid(row=3,column=4)

b4 = tk.Text(win,bd=5,width=5,height=3)
b4.grid(row=2,column=5,sticky=W)
Lb4 = tk.Label(win,text="bit4")
Lb4.grid(row=3,column=5)

b3 = tk.Text(win,bd=5,width=5,height=3)
b3.grid(row=2,column=6,sticky=W)
Lb3 = tk.Label(win,text="bit3")
Lb3.grid(row=3,column=6)

b2 = tk.Text(win,bd=5,width=5,height=3)
b2.grid(row=2,column=7,sticky=W)
Lb2 = tk.Label(win,text="bit2")
Lb2.grid(row=3,column=7)

b1 = tk.Text(win,bd=5,width=5,height=3)
b1.grid(row=2,column=8,sticky=W)
Lb1 = tk.Label(win,text="bit1")
Lb1.grid(row=3,column=8)

b0 = tk.Text(win,bd=5,width=5,height=3)
b0.grid(row=2,column=9,sticky=W)
Lb0 = tk.Label(win,text="bit0")
Lb0.grid(row=3,column=9)

# 循环显示
win.mainloop()
