So this happens and I have tried retyping it the def statement. How can I fix this? I don't know when it started happening or why it happens but I know that I got it working once I think from restarting the program. This is python btw

You should make sure your indentation is uniform (always 4 spaces). Starting with if Submit == "yes":, your lines have one extra space. This will be easier to do if you use a better IDE than IDLE, which will automatically highlight and label problems like this. Some good alternatives are Spyder (which is free), and PyCharm (which is free for students).

Disclaimer: Sorry if the question is stupid or repeated, I've tried to find similar ones that answer what I need to know but I couldn't. I've started to learn programming about 1 month ago and this is my second time on this website. Feel free to point out any errors or better ways to formulate my questions on stackoverflow, I'll be grateful.
Context:
I was trying to find out a way to print a string - in this case ' º ' - after my user's input - an angle -, on the same line.
I need an alternative way to do this, or help with the one I'm using.
What I got from my research is that, apparently, using the command os.system(cls) should erase the previous line, and putting \033[A before the string should move the cursor up one line. So using these two together should erase the previous line and then overwrite it.
Here's my try:
from os import system
cls = lambda: system('cls')
angle = float(input(f'Insert an angle:'))
cls()
print(f'\033[AInsert an angle:{angle}º')
Desired result on run:
Insert an angle: *60*º # being 60 the user's input
Actual result on pycharm:
Insert an angle:60
Insert an angle:60.0º # for some reason, you can't see it when paste it here, but there's a symbol of a crossed rectangle on the beginning of this line on Pycharm's run
How it looks on pycharm's run terminal
As you can see, the line isn't getting overwritten, only repeated.
What is weird is that when I run this program with Python 3.8 instead of Pycharm, it works as intended, but, on Pycharm, the line isn't overwritten. Instead, Pycharm just prints a crossed rectangle symbol.
Why does it work when executing the file with Python 3.8, but not when pressing "run" on pycharm?
Is there a way to avoid it?
Are there better alternatives to printing a string on the same line as an input?
In cases where I need special printing (ANSII escape codes, backspacing...), I use the actual Terminal, not the Python Console.
For whatever reason, interactive consoles, regardless of IDE, seem to have issues with handing specialties like that. With the normal Terminal, it works as expected:
I have never found a way of having the interactive console handle cases like this.
I don't know how this happens or why,
but I'll be in a jupyter notebook grouping by things and I will very conciously type in dataframe.groupby, write some other code and hit ctrl+ enter
and there will be that damn error. Every single time, I will go back and delete the 'groupyouby' and type in groupby.
I doubt that anyone has run into this error,and I don't know how long it will be until someone else creates the mess of libraries that I have that resulted in this chinese water tourture like nightmare. I am here, to let you know, that you are not alone.
Also if someone has a fix that would be great. I got nothing for you other than that description above.
Grammarly was the cause of this.
If you use jupyter notebooks and have the grammarly extension. It will cause problems.
I use Intellij IDEA for python, and it used to show every error I made on it. For some reason now, even if I do something that is clearly wrong, that check mark on the side always shows up. I tried fixing it, but that didn't work.
I'm using Atom at work for editing Python code, and I'm running against a painful interaction between muscle memory and a labor-saving feature.
Near as I can tell, Atom will, when you paste a snippet of code, redo the indentation so that it's consistent with the indentation of the line it was pasted into, preserving relative indents.
If I didn't have any baggage from using editors without this feature, I'm pretty sure it'd be great, but as it is, I can't break my habit of selecting back to the preceding newline, and pasting that, which tends to do crazy things when pasting to or from the first line of a block.
I've tried to turn off Auto Indent on Paste, but it's not on anywhere I can find, and I'm not even sure it's the same feature; it's just what I hear about from people complaining about Atom going crazy when they paste Python.
So, where do I look to disable this? I'm willing to work up from no extensions back to what I've got installed, so assume a vanilla install.
I guess the workflow I'm looking for is "paste, manual re-indent", because at least that way I know what I'm getting and my response is always the same. As it stands, I don't have to think about it until it converts simple line rearrangements into syntactic garbage, which is worse than just adjusting things every time.
EDIT: In response to Milo Price, I have just now tried setting both autoIndentOnPaste and normalizeIndentOnPaste to false. The behavior is unchanged.
FURTHER EDIT: I had to reload the configuration for it to take. It's working now.
You have to set the config options autoIndentOnPaste and normalizeIndentOnPaste both to false, and then reload the configuration.
I am new to python programming... Just wanted to know does IDLE has a concept of 'executing selected statements'??
F5 runs the whole program... Is there any way to do this?
No, not now. Since you are at least the second person to ask this, I added the idea to my personal list of possible enhancements. However, while running a selection would not be a problem, producing accurate tracebacks for exception would be. Doing so is an essential part of Python's operation.
Currently, one can disable code that you need to not run by commenting it out (Alt-F3) or by making it a string. One can stop execution after a particular statement by adding 1/0. Or you can copy code to a new editor window.
Do you have a specific use case in mind, or are you just wondering?
Install Spyder, with its dependecies, and you will have wonderful FREE IDE !
You will have another solution, is to use IPython Notebook, where you will be able to use your Internet Browser to run python codes!:
