Python: replace Japanese word with brace, such as {keyword: 部屋}, {keyword: 公園}, ..... with 'keyword'

Question

there are some Japanese sentences like following:

 {keyword: 部屋}いいね!
 {keyword: 公園}は綺麗です.
 私は{keyword: 部屋捜査}です。

　　　.......... .........

I want to replace the substring like :{keyword: 部屋},{keyword: 公園}..... with 'keyword'.

For example:

input: 私は{keyword: 部屋捜査}です  

output: 私はkeywordです

My trying code is following and but it is wrong, the result is same:

import re
s = '{keyword: 賃貸}'    
t = re.sub(r"\{keyword:[あ-んア-ン一-]+\}", 'keyword', s)
print(t)

Thanks!

What about just matching any chars but `}` after `{keyword:`? Try [`re.sub(r"\{keyword:[^}]*}", 'kd', s)`](https://regex101.com/r/i19GqU/1) — Wiktor Stribiżew, May 31 '18 at 10:47
hi @Wiktor Stribiżew, could you explain your regex in detail, please! — tktktk0711, May 31 '18 at 10:54
Matching a string between two strings is a long solved issue, so I decided to close as a dupe. [This post](https://stackoverflow.com/a/32680048/3832970) shows how to use `.*?` to match from a starting delimiter to the closing one. You do not even need a negated character class if you consider it too complex. — Wiktor Stribiżew, May 31 '18 at 11:04

Use the following:-

inputString = "私は{keyword: 部屋捜査}です"
t = re.sub(r"\{keyword:[^}]*}", 'keyword', inputString)
print(t)

Could you explain in detain, please! for example; what's meaning of '[^}]'? – tktktk0711 Jun 01 '18 at 02:09
Hi @tktktk0711, `[^}]` is used to define one character, that is not `}`. For further details, use reference:- https://docs.python.org/3/howto/regex.html#more-metacharacters and – nandal Jun 01 '18 at 07:08
