好吧，我正在使用Tkinter（3.3）制作一个程序。用户提交名称，然后在数据库cards.cdb中搜索名称，该名称打印出其信息，然后将其与在线源url进行比较。它还使用功能picture显示指定事物的图片。所以当按钮被点击时，它会调用buttonclicked函数，然后调用其他两个函数。作业前的本地变量参考
from tkinter import *
import urllib
import urllib.request
from bs4 import BeautifulSoup
import Pydeck
import sys
from collections import defaultdict
root = Tk()
name=""
def buttonclicked():
name()
picture(text)
def name():
all_lists=[] #all lists
text = inputfield.get()
Pydeck.loadDatabase('C://Users/Trevor/Desktop/Y-In Process/cards.cdb')
cardName = Pydeck.getCardsFromName(text)
if not cardName == "":
c = Pydeck.Card(cardName)
tex.insert(END, c.name)
level="\nLevel %s" % c.level + " " + c.attribute + " " + c.typestring
tex.insert(END, level)
atk="\nAtk: %s" % c.attack
tex.insert(END, atk)
defe="\nDef: %s" % c.defense
tex.insert(END, defe)
typestring='\n%s' %c.typestring
desc='\n%s' %c.description
seperator='\n--------------------\n'
tex.insert(END, typestring)
tex.insert(END, desc)
tex.insert(END,seperator)
#--
url_name=c.name.replace(' ','_')
url=('http://yugioh.wikia.com/wiki/Card_Tips:{}'.format(url_name))
page = urllib.request.urlopen(url)
soup = BeautifulSoup(page.read())
content = soup.find('div',id='mw-content-text')
links = content.findAll('a')
link_lists = defaultdict(list)
all_lists.append([link.get("title") for link in links])
common_links = set(all_lists[0]).intersection(*all_lists[1:])
omit_list=['None', 'Special Summon', 'Edit Searchable by section', 'Edit Special Summoned from the hand by section','Edit Special Summoned from the Deck by section','Edit Special Summoned from the Graveyard by section','Edit Easier Tribute Summons section','Edit Generic Tips section','Edit Traditional Format section']
final=set(common_links)-set(omit_list)
tex.insert(END,final)
#--
tex.see(END) # Scroll if necessary
def picture(text):
gifdir = "C:\\Users\\Trevor\\Desktop\\Y-In Process\\Pictures\\"
Pydeck.loadDatabase('C://Users/Trevor/Desktop/Y-In Process/cards.cdb')
cardName = Pydeck.getCardsFromName(text)
if not cardName == "":
c=Pydeck.Card(cardName)
filename='{}.gif' .format(c.cardID)
img = PhotoImage(file=gifdir+filename)
can = Canvas(root)
can.pack(fill=BOTH,side='left')
can.config(width=img.width(), height=img.height())
can.create_image(2, 2, image=img, anchor=NW)
tex=Text(root)
tex.pack(side='right')
inputfield = Entry(root)
inputfield.pack(side='bottom')
but = Button(root,text="Enter Name", command = buttonclicked) #Calls name function
but.pack(side='bottom')
text = inputfield.get()
root.mainloop()
，我发现了错误
filename='{}.gif' .format(c.cardID)
UnboundLocalError: local variable 'c' referenced before assignment
我知道这意味着没有被创建c但在picture功能我也把它定义但它不承认它。
任何人有任何建议，因为我难住？
