[英]Tkinter - how to print list values in label with each value on different line, newest value first
I am trying to print values from list in a tkinter label.我正在尝试从 tkinter label 中的列表中打印值。 It should work this way: there will be generated some coordinates (in code below a wrote just randint - like example) and every new value will be added on the first position with max.它应该以这种方式工作:将生成一些坐标(在下面的代码中,只写 randint - 例如示例),并且每个新值都将添加到第一个 position 上,最大值为。 10 values in list.列表中有 10 个值。 Problem is that if I just iterate through the list and print value - it works - but if I want to place it on a label via f-string, it only shows one value... For loop I used because it will print every value on different line问题是,如果我只是遍历列表并打印值 - 它可以工作 - 但如果我想通过 f-string 将它放在 label 上,它只显示一个值......我使用的循环是因为它会打印每个值在不同的线路上
list = []
def listappend():
list.insert(0, random.randint(0, 10))
if len(list) > 10:
label_coords_list.pop()
for x in list:
print(x)
label.config(text=f'Current coordinates:\n{x}')
else:
for x in list:
print(x)
label.config(text=f'Current coordinates:\n{x}')
test_button = Button(root, text='Test', width=13, command=listappend)
test_button.place(x=330, y=50)
print(x)
shows this: print(x)
显示了这一点:
6 6
5 5
4 4
0 0
6 6
7 7
0 0
1 1
6 6
each number on its own line每个数字单独一行
and label_coords.config(text=f'Current coordinates:\n{x}')
prints only '6' on the label a doesn not update any more.并且label_coords.config(text=f'Current coordinates:\n{x}')
在 label 上仅打印 '6' a 不再更新。
...as usual - I guess that there are some silly mistakes:) will be grateful for any hint. ...像往常一样 - 我想有一些愚蠢的错误:) 将不胜感激任何提示。
Does replacing:是否更换:
for x in list:
print(x)
label.config(text=f'Current coordinates:\n{x}')
with和
message = ''
for x in list:
print(x)
message += '\n' + str(x)
label.config(text=f'Current coordinates:{message}')
label.pack()
correspond to what you want?对应你想要什么?
