I am trying to get a variable out of wxPython file open dialog. I have 2 button which gets the path to 2 files with .GetPath() ?
this is the code I have so far
'def onclk1(event):
with wx.FileDialog(panel, "OPEN EMG FILE", wildcard="TXT Files(*.txt)|*.txt",
style=wx.FD_OPEN | wx.FD_FILE_MUST_EXIST) as EmgFile:
if EmgFile.ShowModal() == wx.ID_CANCEL:
return "cancelled"
emg = EmgFile.GetPath()
e1.Bind(wx.EVT_BUTTON, onclk1)
Now I need to pass the path outside def to another variable.
Thanks in advance
In future it might be better to provide a minimal working example of your code.
Don't forget that a GUI is event driven and you must use the event to assign the return value of a dialog to the variable you want.
You've not said what you want to do with the file path, but this code shows how to assign it to a label.

I have a code. When it runs, you click on add contact button and add some contact. When you press on each contact, it just shows you the last contact information you have added. But when I press on each contact, I want it to instead show me the information for the contact I have clicked. Who can help me to solve this problem?

Everyone will develop their own style when using wxPython. As Rolf has suggested, you do not just add widgets to a frame, but you need to add a panel. I have added a basic contact add screen below. The 'New' button creates an instance of a wx.Dialog, which captures the details of a contact. These are then available to the MainFrame where you can save them if you want.
Note that I have freely created new classes in the application to handle the different areas of concern. GUI apps can become very complex, and in my opinion, there is no substitute for factoring each bit of functionality into its own method or class.
Not everything needs to be a member of the frame class.
Note also the I have used sizers and not absolute positions.
This code does not do everything that you want to do, but it might help get you started.

I'm trying to make a form that has several input fields. Underneath these fields I want to have a wxpython Ultimate List Control (for all intents and purposes it's the same thing as a List Control). My issue is with sizers. To give some context, my form looks like this
Name [TextCtrl]
Blah [TextCtrl]
ListControl
I want it to look like
Name [TextCtrl]
Blah [TextCtrl]
ListCtrl (this spans to the end of the row)
My problem is when I try to add the List Control. I want the list control to Stretch from The Static Text to the Text Control, but it pushes the TextControl over. Can someone please point me in the right direction? I have attached the relevant code below.
class UserField(wx.Dialog):
def __init__(self, parent):
wx.Dialog.__init__(self, parent=parent, title="Info", size=(350, 400),
style=wx.DEFAULT_FRAME_STYLE)

self.Center()

def init_ui(self):
panel = wx.Panel(self, wx.ID_ANY)
hbox = wx.BoxSizer(wx.VERTICAL)
flex_grid = wx.FlexGridSizer(5, 2, 5, 10) # row, col, vgap, hgap
info_text = wx.StaticText(parent=panel, label="Enter information")
self.search_button = wx.Button(parent=panel, label="Search")
self.list_control = UltimateListCtrl(panel,
agwStyle=wx.LC_REPORT | wx.BORDER_SUNKEN | ULC_HAS_VARIABLE_ROW_HEIGHT, )
flex_grid.AddMany(
[
info_text, self.search_button
]
)
lbox = wx.BoxSizer(wx.HORIZONTAL)

Here's a quick demonstration of wx.GridBagSizer. The program opens a simple frame with a single button that spawns a dialog with a GridBagSizer. You can place items in the sizer according to a position (pos) and optionally allow a widget to span multiple rows and/or columns (span).

field1Ctrl = wx.TextCtrl(panel)
field2Ctrl = wx.TextCtrl(panel)
listCtrl = wx.ListCtrl(panel)
sizer.Add(field1Label, pos=(0, 0))
sizer.Add(field2Label, pos=(1, 0))
sizer.Add(field1Ctrl, pos=(0, 1))
sizer.Add(field2Ctrl, pos=(1, 1))
# HERE'S THE IMPORTANT LINE. NOTE THE 'span' ARGUMENT:
sizer.Add(listCtrl, pos=(2, 0), span=(1, 2), flag=wx.EXPAND)

New python programmer here and trying to learn how to dynamically update widgets. To start, I have the following code. What I would like to do is change my variable "self.dynamiclength" to any integer, and have WxPython update the number of widgets appropriately. I have tried putting self.Refresh() and self.Update() in my TestFrame after updating self.dynamiclength to no avail.
I have done as much reading as possible on this before resorting to asking for help, but I am just too new at Wx to solve this one on my own. Thank you much!

If you need to update the number of widgets AFTER you've already created and shown the application, the you'll need to do it in a method, NOT in the init. The init only runs the first time the application is instantiated. Whenever you add or remove widgets after the frame is shown, you'll need to call Layout() on the parent widget or its sizer.

Try this to see what the error is,
1.you press create new (any amount of times)
2.press, load file
3. click any item on the listbox (except for the one that you are in)
4. Then go back to the orginal item that you were in,
5. Then click any item, other than the one you are currently in
There will be some sort of problem, the image does not destroy itself and returns an error like the following:
(, PyDeadObjectError('The C++ part of the StaticBitmap object has been deleted, attribute access no longer allowed.',), )
I am still able to load images but the previous images do not delete.
It is hard to word this problem, if anyone can help me with this situation, it would be greatly appreciated. If you need further explanation please comment. I thank you greatly for viewing.
Here you have your code fixed to clear your current image when loading another one.
This is done basically using self.parent.bitmap.Destroy().
I modified some few things without changing the structure of your code, in order for you to recognize changes. I eliminated globals calls. Look how I also eliminated the global IMAGE_LISTSEL variable and converted it in a class attribute. That is what Robin and Fenikso were telling you. Try to do the same with IMAGE_NAME and IMAGE_DATA.
Although the code is working, it is still far from being acceptable wxpython code. You can get many examples of correctly written wxpython code in the web. If you can afford it I recommend to you wxPython in Action from Noel Rappin and Robin Dunn.

Sometimes you are using bmp1 and bitmap1 as local variables and sometimes as globals. Since you are making multiple instances of them without saving the prior references anywhere then you are losing your references to the already existing objects. When you Destroy() them then you are only destroying the most recently created instances.
Try adding them to some sort of collection (like a list) instead and then you can access any of the items from the list when you need them later. Also try to avoid using global variables. Store your variables in the object instances that they belong to.
