If colon --> followed by single or multiple spaces --> followed by any alphabet should move it's position to the right side and by leaving space left side.

(如果冒号->后跟一个或多个空格->后跟任何字母，则应将其位置移到右侧，并在左边留空格。)

When I try re.sub(':+ [a-zA-Z]', ' :', string) on #YoTambien: smiling_face_with_heart-eyes --> #YoTambien :smiling_face_with_heart-eyes

(当我尝试在re.sub(':+ [a-zA-Z]', ' :', string) #YoTambien: smiling_face_with_heart-eyes --> #YoTambien :smiling_face_with_heart-eyes)

re.sub is replacing the entire pattern and returning #YoTambien :miling_face_with_heart-eyes , but, I just want to move the position of the colon, but not to override with "S".

(re.sub替换了整个模式并返回#YoTambien :miling_face_with_heart-eyes ，但是，我只想移动冒号的位置，而不是用“ S”覆盖。)
