The requirement is to replace the better in text with that strong
in the regular mode of the sub method, where I have added r to indicate escape.
Why add a\, written as r"\ * (. *?)\ *?
Why can"t you just write ringing * (. *?) *?
what do the two here do?
related codes
text = "Beautiful is better than ugly."
re.sub (r"\ * (. *?)\ *," , text)
what result do you expect? What is the error message actually seen?
in the regular mode of the sub method, I have added r in front to indicate escape.
Why add a\, written as r"\ * (. *?)\ *?
Why can"t you just write ringing * (. *?) *?
what I need is between * and *, and I don"t need * to represent the quantity, so why add\ * after r to escape *?
