python - 为什么我在 Emacs 中得到了太多的标签？

Question

初始化.el

(setq make-backup-files nil)

(add-to-list 'load-path "~/.emacs.d/")

; Add all top-level subdirectories of .emacs.d to the load path
(progn (cd "~/.emacs.d")
       (normal-top-level-add-subdirs-to-load-path))
; Third party libraries are stored in ~/.emacs.d/extern
(add-to-list 'load-path "~/.emacs.d/extern")
(progn (cd "~/.emacs.d/extern")
       (normal-top-level-add-subdirs-to-load-path))

; Python-specific enchancements
(load-library "python")

; Zenburn color theme
(require 'color-theme-zenburn)

(color-theme-zenburn)

python.el

; use tabs in files (urgh...yelp!)
;(setq-default indent-tabs-mode t)

; tab display width of 4 columns by default
; (throw everything at the wall, and eventually something will stick...)
;(setq-default tab-width 4)  ; Normal emacs tab-width
; (setq-default c-basic-offset 2) ; python-mode.el setting
;(setq-default py-indent-offset 4) ; Use Tabs, not spaces
;(setq-default py-smart-indentation nil) ; Don't try to guess tab width

(defun customize-py-tabs ()
    (setq tab-width 4
        py-indent-offset 4
        indent-tabs-mode t
        py-smart-indentation nil
   )
)

(add-hook 'python-mode-hook 'customize-py-tabs)

; Highlight useless whitespace
(add-hook 'python-mode-hook
                  (lambda () (setq show-trailing-whitespace t)))

我正在尝试将我的 emacs 设置为在我的 python 代码中切换到正确的级别，但它添加了额外的选项卡。它是一致的。如果应该有 4 个选项卡，我得到 5 个。有什么建议吗？

例如

def func:
        # This is where it puts me
    # This is where it SHOULD put be

任何以 tab-width 设置为 8 以外的值开始的 Python 缩进注定会带来麻烦。 tab-width 决定 Emacs 如何显示 TAB 字符，而不是 多远 以响应点击tab键。
