如何在tkinter中修改標簽？-有解無憂

我一直在想辦法修改標簽以在一行中列印元素 1 到 4 并重復。我附上了一張圖片，希望能澄清我想要完成的事情。

我的目標是使結果如下所示

1 A 2 B 3 C 4 D

1 a 2 b 3 c 4 d

如何在 tkinter 中修改標簽？

my_entries = []

#prints the result
def something():
   entry_list =''
   index = 0
   for entries in my_entries:
      index =1
      print(entries.get()   ' '  str(index))
      entry_list = entry_list   str(index)   ' '   str(entries.get())   '\n'
      if index == 4:
         index = 0
      my_label.config(text=entry_list)
   
   #prints the element
   print('\n' my_entries[1].get())


def get_value():
    my_entries.clear()
    value = vialEntry.get()
    try:
        #print(int(value))
        return int(value)
    except ValueError:
        return None

#this function will create the inputs for the vials elements 
def make_entry():  
   num = get_value()
   print(num)
   tk.Label(master, text = "Name ").grid(row=1, column=1)
   tk.Label(master, text = "Time ").grid(row=1, column=2)
   tk.Label(master, text = "Temp ").grid(row=1, column=3)
   tk.Label(master, text = "Freq ").grid(row=1, column=4)
   #row loop
   for y in range(num):
      #column loop
      for x in range(4):
         user_entery = Entry(master)
         tk.Label(master, text = "Element: " str(y 1)).grid(row=y 2, column=0, pady=5)
         user_entery.grid(row=y 2, column=x 1, pady=0, padx=5)
         my_entries.append(user_entery)

#end of make_entry function

my_button = Button(master, text="Click me", command=something)
my_button.grid(row=23, column=0, pady=20)
tk.Label(master, text = "Results: ").grid(row=24, column=0)
my_label = Label(master, text='')
my_label.grid(row=25, column=0, pady=0)

uj5u.com熱心網友回復：

您\n在每個索引/值對之后添加。您需要\n在 4 個索引/值對之后添加：

def something():
   entry_list =''
   index = 0
   for entries in my_entries:
      index =1
      print(entries.get()   ' '   str(index))
      entry_list  = str(index)   ' '   str(entries.get())
      if index == 4:
         index = 0
         entry_list  = '\n'
      else:
         entry_list  = ' '

   my_label.config(text=entry_list)

   #prints the element
   print('\n' my_entries[1].get())

請注意，for 回圈可以簡化如下：

def something_():
    entry_list = ''
    for i, entry in enumerate(my_entries):
        entry_list  = f'{i%4 1} {entry.get()}'   ('\n' if i%4 == 3 else ' ')
    # or one-liner
    #entry_list = ''.join(f'{i%4 1} {entry.get()}'   ('\n' if i%4 == 3 else ' ') for i,entry in enumerate(my_entries))
    my_label.config(text=entry_list)
