问题描述
我正在使用tkinter编写程序，以查找均值或中位数（取决于用户选择的是哪个）。在找到均值的同时，中位数仅在我打印值时才起作用（而不是配置文本）。
我评估了（使用 import image
img = image.Image("cy.jpg")
win = image.ImageWin(img.getWidth(),img.getHeight())
img.draw(win)
img.setDelay(1,15) # setDelay(0) turns off animation
for row in range(img.getHeight()):
for col in range(img.getWidth()):
p = img.getPixel(col,row)
newred = 255 - p.getRed()
newgreen = 255 - p.getGreen()
newblue = 255 - p.getBlue()
newpixel = image.Pixel(newred,newgreen,newblue)
img.setPixel(col,row,newpixel)
img.draw(win)
win.exitonclick()
的值以找到中位数，但是它给出了以下错误：
eval()这是我的代码的一小部分：
TypeError: can only concatenate str (not int) to str.
但是，当我from tkinter import *
import statistics
root = Tk()
class stats:
def __init__(self,constant):
# Determines the type of stat used. e.g-> mean,median,mode,etc...
self.types_list = ["mean","median"]
self.type = self.types_list[1]
self.values = []
self.answer_label = Label(constant,text = "",bg = "light green")
self.answer_label.place(relx = .2,rely = .7,relwidth = .3,relheight = .2)
self.type_label = Label(constant,text = "It is set to Median",bg = "light green")
self.type_label.place(relx = .843,rely = 0,relwidth = .15,relheight = .1)
self.input_data = Entry(constant)
self.input_data.place(relx = .45,rely = .05,relwidth = .25,relheight = .05)
self.check = Button(constant,text = "Check",bg = "red",command = self.get_values)
self.check.place(relx = .65,relwidth = .1,relheight = .05)
self.mean = Button(constant,text = "Mean",command = self.set_mean)
self.mean.place(relx = .4,rely = .5,relwidth = .2,relheight = .2)
self.median = Button(constant,text = "Median",command = self.set_median)
self.median.place(relx = .2,relheight = .2)
def set_mean(self):
self.type = self.types_list[0]
self.type_label.config(text = "It is set to Mean")
def set_median(self):
self.type = self.types_list[1]
self.type_label.config(text = "It is set to Median")
def get_values(self):
# Iterates through each number in entry widget
self.values = self.input_data.get()
# If it's mean
if self.type == self.types_list[0]:
mean = statistics.mean(eval(self.values))
self.answer_label.config(text = mean)
# If it's median
elif self.type == self.type_label[1]:
median = statistics.median(eval(self.values))
self.answer_label.config(text = median)
s = stats(root)
mainloop()
且未将print(statistics.median(eval(self.values)))设置为type时，它起作用。
如果有人愿意提供帮助，我将很荣幸！或者，如果有任何改进-更好的变量名，简单性（我将解决），或者即使我的问题过长，也可以注释或包括在答案中。如果您需要进一步澄清我的问题，也请发表评论。
