用python实现计算器，他应该有以下功能：1.首先它是有gui界面的.2他可以进行加减乘除最基本的四则运算.3他可以进行十进制转换成其他任意进制4有清除键

好的，您可以使用Python中的tkinter模块来创建一个GUI界面的计算器，具有您提到的所有功能。

以下是一个简单的示例代码：

from tkinter import *

def clear():
    display.delete(0, END)
    
def button_click(number):
    current = display.get()
    display.delete(0, END)
    display.insert(0, str(current) + str(number))
    
def add():
    first_number = display.get()
    global f_num
    global math
    math = "addition"
    f_num = float(first_number)
    display.delete(0, END)
    
def subtract():
    first_number = display.get()
    global f_num
    global math
    math = "subtraction"
    f_num = float(first_number)
    display.delete(0, END)
    
def multiply():
    first_number = display.get()
    global f_num
    global math
    math = "multiplication"
    f_num = float(first_number)
    display.delete(0, END)
    
def divide():
    first_number = display.get()
    global f_num
    global math
    math = "division"
    f_num = float(first_number)
    display.delete(0, END)
    
def convert():
    decimal_number = int(display.get())
    base = int(input("Enter the desired base: "))
    converted_number = ''
    while decimal_number > 0:
        remainder = decimal_number % base
        converted_number = str(remainder) + converted_number
        decimal_number = decimal_number // base
    display.delete(0, END)
    display.insert(0, converted_number)
    

def equal():
    second_number = display.get()
    display.delete(0, END)
    
    if math == "addition":
        display.insert(0, f_num + float(second_number))
        
    if math == "subtraction":
        display.insert(0, f_num - float(second_number))
        
    if math == "multiplication":
        display.insert(0, f_num * float(second_number))
        
    if math == "division":
        display.insert(0, f_num / float(second_number))


root = Tk()
root.title("Calculator")

display = Entry(root, width=35, borderwidth=5)
display.grid(row=0, column=0, columnspan=4, padx=10, pady=10)

button_1 = Button(root, text="1", padx=40, pady=20, command=lambda: button_click(1))
button_2 = Button(root, text="2", padx=40, pady=20, command=lambda: button_click(2))
button_3 = Button(root, text="3", padx=40, pady=20, command=lambda: button_click(3))
button_4 = Button(root, text="4", padx=40, pady=20, command=lambda: button_click(4))
button_5 = Button(root, text="5", padx=40, pady=20, command=lambda: button_click(5))
button_6 = Button(root, text="6", padx=40, pady=20, command=lambda: button_click(6))
button_7 = Button(root, text="7", padx=40, pady=20, command=lambda: button_click(7))
button_8 = Button(root, text="8", padx=40, pady=20, command=lambda: button_click(8))
button_9 = Button(root, text="9", padx=40, pady=20, command=lambda: button_click(9))
button_0 = Button(root, text="0", padx=40, pady=20, command=lambda: button_click(0))

button_clear = Button(root, text="Clear", padx=80, pady=20, command=clear)
button_convert = Button(root, text="Convert", padx=76, pady=20, command=convert)
button_add = Button(root, text="+", padx=39, pady=20, command=add)
button_subtract = Button(root, text="-", padx=41, pady=20, command=subtract)
button_multiply = Button(root, text="x", padx=40, pady=20, command=multiply)
button_divide = Button(root, text="/", padx=41, pady=20, command=divide)
button_equal = Button(root, text="=", padx=91, pady=20, command=equal)

button_1.grid(row=3, column=0)
button_2.grid(row=3, column=1)
button_3.grid(row=3, column=2)

button_4.grid(row=2, column=0)
button_5.grid(row=2, column=1)
button_6.grid(row=2, column=2)

button_7.grid(row=1, column=0)
button_8.grid(row=1, column=1)
button_9.grid(row=1, column=2)

button_0.grid(row=4, column=0)

button_clear.grid(row=4, column=1, columnspan=2)
button_convert.grid(row=5, column=0, columnspan=2)
button_add.grid(row=1, column=3)
button_subtract.grid(row=2, column=3)
button_multiply.grid(row=3, column=3)
button_divide.grid(row=4, column=3)
button_equal.grid(row=5, column=2, columnspan=2)

root.mainloop()

这将创建一个简单的计算器GUI，您可以单击按钮执行所需的操作。

同样，十进制转换功能只能在命令行上使用，因为它需要输入所需进制的值。 您也可以在GUI中添加一个输入框以获取所需进制，但这超出了此示例的范围。
