Extract data from text file

Hello! Please help me. I need a code to extract data from a large text file.

This includes data like this:

146.204.224.152 - feest6811 [21/Jun/2019:15:45:24 -0700] "POST /incentivize HTTP/1.1" 302 4622

197.109.77.178 - kertzmann3129 [21/Jun/2019:15:45:25 -0700] "DELETE /virtual/solutions/target/web+services HTTP/2.0" 203 26554

156.127.178.177 - okuneva5222 [21/Jun/2019:15:45:27 -0700] "DELETE /interactive/transparent/niches/revolutionize HTTP/1.1" 416 14701

159.253.153.40 - - [21/Jun/2019:15:46:10 -0700] "POST /e-business HTTP/1.0" 504 19845

100.32.205.59 - ortiz8891 [21/Jun/2019:15:45:28 -0700] "PATCH /architectures HTTP/1.0" 204 6048

233.187.15.207 - - [21/Jun/2019:15:46:14 -0700] "GET /harness/intuitive HTTP/1.0" 304 21006

168.95.156.240 - stark2413 [21/Jun/2019:15:45:31 -0700] "GET /engage HTTP/2.0" 201 9645

It is needed to be converted into a list of strings like this:

"host: 146.204.224.152"

"username: feest6811"

"time: 21/Jun/2019:15:45:24 -0700"

"request: POST /incentivize HTTP/1.1"

sometimes there are no username so instead it is changed into a dash line
