| IDLE doesn't highlight f-strings like r-strings or u-strings. See the attached screenshot. |

| I've attached a patch that colorizes f-strings. The issue is marked as "test needed" which the dev guide says "... reporter should post a script or instructions to let a triager or developer reproduce the issue." Steps to re-create are to open an IDLE window and type in the code ``` f"123" F"123" u"123" ``` and notice the colorization difference. |

| There are 10 possible f-string prefixes, including combinations with r/R. See https://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals While adding these, I noticed that IDLE was coloring now invalid ur prefixes and deleted those. I decided to test by modifying the existing human visual htest. Ammar: thank you for submitting a patch. It happens that I wrote my patch before I saw your submission. If I had seen yours first, I might have given you a chance to finish it. Feel free to try another IDLE issue. |

| Thank you for the new feature (I presume) and its application. I disliked both writing and reading all the near duplication. I am posting this to python-list as an example of what the new feature is good for. |

| Thank you for advertising the new feature. Would you like to improve the documentation? It always was the hardest part to me. |

| The doc appears to be carefully accurate, but the second sentence especially is a bit awkward. I will open a new issue. |

| #29287 is about syntax highlighting the code within f-strings as code rather than as part of the string. |
