Have that in python-mode.el --as older Emacsen might miss the function--:

;; subr-x.el might not exist yet
(unless (functionp 'string-trim)
   (defsubst string-trim (string &optional trim-left trim-right)
     "Trim STRING of leading and trailing strings matching TRIM-LEFT and 
TRIM-RIGHT.

TRIM-LEFT and TRIM-RIGHT default to \"[ \\t\\n\\r]+\"."
     (string-trim-left (string-trim-right string trim-right) trim-left))
