Python ttk 计算器 之前花了很大心思
'''frame框架布局在frame内部，可以重新进行一次布局'''
import ttkbootstrap as ttk
from ttkbootstrap.constants import *
from PIL import ImageTk,Image
win = ttk.Window()
win.title("计算器")
win.geometry("320x287+500+200")

# 设置窗体图标
win.iconbitmap("./py_pic/jsq3.ico")

style.configure("TButton",font=("微软雅黑",13))

# 通过循环批量制作按钮

if ci != 0 and ci % 5 == 0:
ri += 1 # 换行

'''单击事件绑定

win.mainloop() 代码看起来基本是完整的。你需要引入一些模块，以及创建窗口、按钮等部件，并设置它们的样式和功能。
但是，有几个问题需要注意：
1. `import ttkbootstrap as ttk` 这行代码可能会导致错误，因为`ttkbootstrap`库可能没有安装或找不到。你可以尝试使用标准的`tkinter.ttk`模块代替。
2. 你在代码中使用了一个图标文件作为窗口的图标，但是需要将图标文件提供给程序，并确保路径正确。否则，你可以跳过设置图标这一步。
3. 在代码中有如下几处错误：
- `style.configure("TButton",font=("微软雅黑",13))` 应该改为 `style.configure("TButton", font=("微软雅黑",13))`
- `btn1 = ttk.Button(box,text=v,width=4,bootstyle=(SUCCESS, OUTLINE))` 应该改为 `btn1 = ttk.Button(box,text=v,width=4,style='success-outline')`
- 图片处理部分的代码可能不完整或有错误。建议直接使用透明的等于号图片，而不是通过代码进行处理。
根据你的代码脉络，我稍微修改了部分代码并删除了不能运行的部分。以下是一个修正后的示例代码：
import tkinter as tk
from tkinter import ttk
win = tk.Tk()
win.title("计算器")
win.geometry("320x287+500+200")
win.resizable(width=False,height=False) # 设置不能调整窗口大小
style = ttk.Style()
style.configure("TButton", font=("微软雅黑", 13))
def calcu(e):
txt = str(e.widget)
if txt == "取余":
txt = "%"
elif txt == "整除":
txt = "//"
# 根据你的逻辑进行按钮操作
def theEqual_Click():
# 根据你的逻辑进行等号按钮操作
varLabel0 = tk.StringVar()
varLabel0.set("计算过程区：")
label0 = ttk.Label(win, font=("宋体",15), textvariable=varLabel0)
label0.grid(sticky=tk.EW)
varEntry1 = tk.StringVar()
entry1 = ttk.Entry(win, font=("微软雅黑",15), textvariable=varEntry1)
entry1.grid(sticky=tk.EW)
box = ttk.Frame(win)
box.grid(row=2, column=0)
btnText = [
"1", "2", "3", "+", "-",
"4", "5", "6", "*", "/",
"7", "8", "9", "C", "删除",
]
ri = 0
ci = 0
for v in btnText:
if ci != 0 and ci % 5 == 0:
ri += 1
ci = 0
btn1 = ttk.Button(box, text=v, width=4)
btn1.bind("<Button-1>", calcu)
btn1.grid(row=ri, column=ci)
ci += 1
btn_0 = ttk.Button(box, text="0")
btn_0.bind("<Button-1>", calcu)
btn_0.grid(row=ri+1, column=0, columnspan=2, sticky=tk.EW)
btnDP = ttk.Button(box, text=".")
btnDP.bind("<Button-1>", calcu)
btnDP.grid(row=ri+1, column=2, sticky=tk.EW)
btnTS = ttk.Button(box, text="取余")
btnTS.bind("<Button-1>", calcu)
btnTS.grid(row=ri+1, column=3, sticky=tk.EW)
btnCE = ttk.Button(box, text="整除")
btnCE.bind("<Button-1>", calcu)
btnCE.grid(row=ri+1, column=4, sticky=tk.EW)
btnEqual = ttk.Button(box, text="=", command=theEqual_Click)
btnEqual.grid(row=ri+2, column=0, columnspan=5, sticky=tk.EW)
win.mainloop()
这段代码可以创建一个简单的计算器窗口，具有按钮和文本框。你可以根据自己的需求进行修改和扩展。希望能对你有所帮助！
