BTW, you will get a more complete backtrace if you load the source file instead of the byte-compiled file, for the code that defines run-python. (https://emacs.stackexchange.com/a/20265/12031)

How do I load the source file for debug purpose?

currently I have

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  replace-regexp-in-string("\\`\\^" "" nil)
  python-shell-comint-end-of-output-p(">>> ")
  python-util-comint-end-of-output-p()
  python-eldoc--get-doc-at-point()
  python-eldoc-function(#f(compiled-function (string &rest plist) #<bytecode -0xec60eba7fe247cd>))
  #f(compiled-function (f) #<bytecode -0x191cde0269aa4cd>)(python-eldoc-function)
  eldoc--documentation-compose-1(nil)
  eldoc-documentation-compose()
  eldoc--invoke-strategy(nil)
  eldoc-print-current-symbol-info()

  apply(#<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_11> nil)
  timer-event-handler([t 0 0 500000 nil #<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_11> nil idle 0 nil])

Simply specify the .el suffix explicitly, using any of the load methods.

Interactively, that's one of:

  • M-x load-library RET python.el
  • M-x load-file RET /path/to/python.el

Or you can visit the .el file and use M-x eval-buffer

  • python.el was a problem in the linked question, but in this question it looks as if eldoc stuff needs to be loaded: all of the byte-compiled gobbledegook seems to come from a timer that runs an anonymous function (sigh...) and functions called from eldoc-documentation-compose-1 and python-eldoc-function. Loading python.el is not going to help in this case.
