I am trying to make a list from a text file (.txt) with python regular expression re. Some parts of the text are showing below.

146.204.224.152 - feest6811 [21/Jun/2019:15:45:24 -0700] "POST /incentivize HTTP/1.1" 302 4622\n197.109.77.178 - - kertzmann3129 [21/Jun/2019:15:45:25 -0700] "DELETE /virtual/solutions/target/web+services HTTP/2.0" 203 26554

May I know that how can I regex the text with a list format as:

{
"host_name": "146.204.224.152", 
"name": "feest6811", 
"time": "21/Jun/2019:15:45:24 -0700", 
"method": "POST /incentivize HTTP/1.1"
},
..
..
..

I'm trying to regex with this pattern since I saw example with this pattern:

pattern="(?P<host_name>.*)(\ -\ )(?P<name>\w*)"

for item in re.finditer(pattern,'Text_data',re.VERBOSE):
    print(item.groupdict())

Any suggestion to regex from this text.

Use

(?m)^(?P<host_name>[\d.]+) - (?P<name>\w+) \[(?P<time>[^][]+)] "(?P<method>[^"]+)"

See proof.
