over writing in Spyder

Guys I am using Spyder ide, but when I go to modify a certain thing in any line it selects the letter and starts typing above it and deletes the already written code rather than spacing and typing, any solution?

I would try to hit the Insert key on your keyboard first and see if it toggles between the Insert mode and the Overtype mode:
overtype mode, in which the cursor, when typing, overwrites any text that is present in the current location; and
insert mode, where the cursor inserts a character at its current position, forcing all characters past it one position further.
The insert/overtype mode toggling is not global for the computer or
even for a single application but rather local to the text input
window in which the Insert key was pressed.

Automatically populate python input prompt with default value

The code:
input("Type your input here:)
displays as:
Type your input here:
I want to automatically populate the input window with text that can be cleared by pressing backspace so the display looks like:
Type your input here: DEFAULT
and after pressing backspace 3 times the user would see:
Type your input here: DEFA
Other posts have indicated that this isn't something you can do in, say, bash, but is there a way to do this in Python?

Simple answer: No. It's just not something you can do in a console app. What's commonly done is to display the default you'll get if you press return:
Type your input here [DEFAULT]:

Why is the 'send_keys' command pressing the enter key after it fills the text box?

I am trying to fill a form with selenium, which requires me to pull names from a .txt file and assign them to a variable, and then filling a text box using the value from that variable. It successfully fills the desired box, but it presses the 'enter' key right after it fills, which submits the form before the script can fill the other boxes.
I have tried making the script fill the First Name box last, but the form requires information to be filled in the order they are arranged of the website.
# Assigns a random name to var 'firstname'
firstname = (random.choice(list(open('names.txt'))))
# Fills the First Name input
first = driver.find_element_by_css_selector('#first_name')
first.send_keys(firstname)
The code should fill in the first name box and continue to fill in the rest of the form, but instead only fills the first box and then presses the enter key, which prematurely submits the form. I know it is an issue with sending the variable because when I change the code to: first.send_keys('firstname')
The script works as intended.

Editing text in a wx.textcontrol with wx validator

I have a validator which Ive attached to a wx.TextCtrl inside a wx.Dialog:
myinput = wx.TextCtrl(self, validator=MyValidator())
All that validator does is it binds a wx.EVT_CHAR event and checks whether the input is a number and whether the number of characters entered is less than 5.
The problem is when I select the text with my mouse i.e. turn it to blue I cant replace the text if the number of characters is already at its maximum.
How can I detect whether the user has selected the text of that specific text box and has pressed a key?

Take a look at how the IntValidator inside the file wx\lib\intctrl.py is created.
Now use the intctrl instead of creating your own and limit the characters entered to 4 by using the method SetMaxLength(4)

send key code to field

i want to simulate the pressing of the enter key using py-appscript
i already found this, but it seems to only output the newline
Translate Applescrip [key code 125 using command down] to appscript
right now i want to press the enter key after the value has been set.
Example, after entering the IP hit enter key.
or send a keycode to the field itself.

app('System Events').key_code(76). (Or key_code(36) or keystroke('\r') if you meant ↩ instead of ⌤.)
keystroke and key_code don't ignore keys actually held down by the user, so you might need to add a delay if you're using a shortcut with modifier keys used to run the script.
