Let's say I'm on line 500 in spyder, and I want to run everything from that line and above (lines 1-500), is there a shortcut to select the lines quickly. Right not I'm highlighting the lines and scrolling up and using shift and up arrow but both of them take some time to scroll. Is there a faster way to select, similar to select all but only for the specific lines 1-500?
(Spyder maintainer here) The easiest way to do what you want is by creating code cells. These are sections in your file separated by comments of the form # %%, which can be run independently by placing the cursor inside them and pressing the shortcuts Ctrl+Enter (run cell) and Shift+Enter (run cell and and advance to the next one).
Please refer to our documentation for more details.
This post is old I know, but I found out that CTRL-Shift-Home doesn't work for me.
I have to use CTRL-Alt-Shift-Home to select everything above the line or -End for everything below.
This is for Windows 7 and Spider 3.3.6
Just in case someone is interested in deleting all the lines, and only find this question after searching, the easy way would be using
'''
for all the codes between the two lines, and then use the triangle on the left to suppress, so you could delete in one go.

I am not able to click(I can say it's diabled) step in, step out, step over option in pycharm debugger
I don't know if this is exactly what is causing your issues but here is one possibility:
All debugging options are grayed out in the menu if your cursor is on an empty line or a line that is a comment. Try putting your cursor on an actual line with code. The "Toggle Line Breakpoint" option in the "Run" menu should now become active. After starting the script with "Run -> Debug", the breakpoint will be triggered (assuming the code reaches it) and the other debug options such as "Step over" become available.
As mentioned in this answer: https://stackoverflow.com/a/48665161/2891209
Depending on what you're trying to debug it is possible for step-in to not show you code which isn't pure python. Pycharm will do the best it can of course, but if the function you're trying to debug isn't native python be prepared for anything...
If you're trying to step into a python wrapped C library function
Sometimes the debugger will skip over that code completely.
Sometimes you can walk the frames but the editor can't show you lines of code.
Sometimes you'll be able to step into an empty skeleton of a function.
It really depends on how the library was created.
I'm new to Python.
I'm using Spyder 4.0.1, Python 3.7.
The Spyder built-in PEP-8 convention code style check returns error E501 (line too long). Although I set the vertical line and wrap lines, it still shows error for the long characters line. Pycharm would wrap lines automatically, but I cannot find any effective solution in Spyder.
What should I do? Do I have to press Enter manually for the long line? Thanks.
In Windows Go To
Tools->Preferences->Editor and select Wrap lines.
If you use mac, you need to go to Python on the left right corner then click on Preferences.
Then go to Editor, and check Wrap lines.
To turn on the Word Wrap feature, go to View > Toggle Word Wrap or click the Edit Display icon in the Code Editor toolbar (it's the second-to-last one on the right) and select Toggle Word Wrap. You can also set the program preferences to keep this feature on by default.
I use MacOS. With other editors I've used, I can hold down Control+Shift followed by a combination of p or n to select multiple lines above or below the current point. I've read through the keybindings under Preferences -> Keyboard shortcuts but I can't figure it out.

Is there a way to autocomplete brackets in spyder?!
Also is there a way to get auto indentation?
I risk making this too broad but is there also a way to make sure that if say I'm defining a function, I can simply click at the end of the function without highlighting everything to make it run.
Example:
def print_twice(Spam):
print(Spam)
print(Spam)
In the above I would like to run the last line but have spyder run everything from def print_twice(Spam) to print(Spam)
Thanks and sorry if the question is annoying or already has an answer. Couldn't find it.
(Spyder maintainer here) My answers:

Brackets are auto-completed automatically by default.
Also is there a way to get auto indentation?
Auto-indentation works automatically too, after : or by aligning your code on open parenthesis.

No, but you can create a cell to run your function. Cells are regions in your code delimited by comments of the form # %% and you can run them with Ctrl+Enter (run cell and stay on it) or Shift+Enter (run cell and advance to next one).
If you have a script open in the Windows version of R, you can run a line (or section of highlighted code) in the shell by hitting CTRL-R (believe it's command-enter in apple version). Is there similar functionality for IDLE? Many thanks
No
In the shortcut key list in IDLE, in Options > Configure IDLE > Keys, in the Action - Key(s) list, one does not find any shortcut key for executing selected code.
IDLE with IdleX supports the ability to run a single line of code or a selection by pressing F9. It also has subCodes which allows you to run code in between '##' comments. It has the same effect as highlighting a lot of code for execution, but you don't need to keep highlighting each time.
If you type part of your search string before hitting Alt+P, then Alt+P will find only items starting with what you typed.
