Question

你好，我在圆计算器的区域中添加了一个GUI，但出现此错误


C:\Users\Timothy\Desktop>python aoc.py
  File "aoc.py", line 12
    var = variable.get()
                       ^
IndentationError: unindent does not match any outer indentation level

这是我的代码，我不知道这是一个漂亮的代码，但对我来说还可以

from tkinter import *
from tkinter import messagebox
pi = 3.14159265359
screen = Tk()
screen.title("Area of Circle Calculator")
screen.geometry("800x500")
C = Canvas(screen, bg="#ED553B", height=25, width=800)
C.grid()
def submit():
    r = float(radius.get())
    an = int(pi * r*r)
    var = variable.get()
    if var == "in2":
        line = Label(screen, text = "_________________________________________")
        ra = Label(screen, text = "Radius: %f" %(r) "in2")
        p = Label(screen, text = "PI: 3.14159265359")
        a = Label(screen, text = "Area of circle %f"  % (an))
        eline = Label(screen, text = "_________________________________________")
        line.grid()
        ra.grid()
        p.grid()
        a.grid()
        eline.grid()

messagebox.showinfo("Information","The area of circle is  %f"  % (an))

units = Label(screen, text = "Units")
units.grid()
variable = StringVar(screen)
variable.set("Unit") # default value

w = OptionMenu(screen, variable, "in2", "cm2", "m2")
w.grid()
ask = Label(screen, text="What is the radius of the circle?")
ask.grid()

radius = Entry(screen)
radius.grid()

done = Button(screen, text="submit", command=submit)
done.grid()

screen.mainloop()

非常感谢您的答复/答复我尝试取消缩进，即使我知道我不会工作，但我尝试查看是否可以解决我的问题
