首先PhotoImage注意這里只支持gif格式的圖片

photo = PhotoImage(file="D:/python/images/02.gif")

發(fā)現(xiàn)tkinter是只支持gif的格式，如果要加載png或者jpg的話就要使用PIL模塊

from tkinter import *
from PIL import Image, ImageTk

root = Tk()
root.title('測試組python畢業(yè)題')

img = Image.open('ques.png')  # 打開圖片
photo = ImageTk.PhotoImage(img)  # 用PIL模塊的PhotoImage打開
imglabel = Label(root, image=photo)
imglabel.grid(row=0, column=0, columnspan=3)

Label(root, text="Answer:").grid(row=1, column=0, sticky=S + N)

answerEntry = Entry(root)
btn = Button(root, text="Submit", command='submit')

answerEntry.grid(row=1, column=1)
btn.grid(row=1, column=2)

mainloop()

但運(yùn)行時(shí)會(huì)報(bào)

ModuleNotFoundError: No module named 'PIL'

運(yùn)行命令:

pip install pillow

D:\Program Files\Python37>pip install pillow
Collecting pillow

     |████████████████████████████████| 2.0MB 133kB/s

如果運(yùn)行該命令 顯示

Requirement already satisfied: Pillow in c:\program files (x86)\python\lib\site-packages (3.4.2)

則表示已經(jīng)安裝過了

如果已安裝則先卸載以獲取最新的pillow
運(yùn)行命令: pip uninstall pillow
然后運(yùn)行:pip install pillow
就可以了

補(bǔ)充：解決python tkinter 展示jpg、png格式圖片的問題

報(bào)錯(cuò)：

from tkinter import *
 
img = PhotoImage(file = r'D:\test\hero\暗黑元首\暗黑元首.jpg')
lable_show = Label(frame_show,imag = img)

解決：首先安裝PIL庫，使用pip命令

pip install pillow

然后使用PIL庫獲得ImageTk.PhotoImage對象代替tk.PhotoImage對象即可

from PIL import Image,ImageTk
 
img = ImageTk.PhotoImage(Image.open(r'D:\test\hero\暗黑元首\暗黑元首.jpg'))
lable_show = Label(frame_show,imag = img)
