英文:
Visual Elements not updating in real time with Taipy GUI
问题
对不起，我不会为您翻译代码。
英文:
Is it normal that when I attempt to add a value to my list or change my data using a button, I do not observe any modifications on the GUI?
Despite this, after refreshing the page, the accurate list is displayed.
from taipy.gui import Gui
import pandas as pd
a_list = [1,2,3]
data = pd.DataFrame({"x":[1,2,3], "y":[2,1,3]})
md = """
<|Update|button|on_action=update|>
# My list
<|{a_list}|>
# My data
<|{data}|table|width=fit-content|>
"""
def update(state):
state.a_list.append(4)
state.data["y"] = [10, 4, 3]
Gui(md).run()
For example, in the code above, clicking the button should add 4 to my list and change my table. However, I see no modification in real time. When I refresh my page, I see the right modifications.
After clicking and before refreshing:

Taipy在这一组特定赋值（.append()，.drop()）中不直接更改您的GUI。要实时看到更改，您必须使用普通的“等于”赋值（state.xxx = yyy）。您的代码将如下所示：
from taipy.gui import Gui
import pandas as pd
a_list = [1,2,3]
data = pd.DataFrame({"x":[1,2,3], "y":[2,1,3]})
md = """
<|Update|button|on_action=update|>
# My list
<|{a_list}|>
# My data
<|{data}|table|width=fit-content|>
"""
def update(state):
state.a_list += [4]
temp = state.data
temp["y"] = [10, 4, 3]
state.data = temp
Gui(md).run()
请注意，这是一段Python代码示例，包括Taipy的GUI元素和一个用于更新GUI的函数。
英文:
Taipy does not directly change your GUI with this set of specific assignments (.append(), .drop()). You must use a regular ‘equals’ assignment to see changes in real time (state.xxx = yyy). Your code will look like this:
from taipy.gui import Gui
import pandas as pd
a_list = [1,2,3]
data = pd.DataFrame({"x":[1,2,3], "y":[2,1,3]})
md = """
<|Update|button|on_action=update|>
# My list
<|{a_list}|>
# My data
<|{data}|table|width=fit-content|>
"""
def update(state):
state.a_list += [4]
temp = state.data
temp["y"] = [10, 4, 3]
state.data = temp
Gui(md).run()
