修改多级嵌套列表以制作单级列表

Question

If I have a list formed by the command dic.keys() like this:

[
  "['my', 'modem']", "['technical', 'schematics']", "['still', 'glad']",
  "['spent', 'calling']", "['most', 'feared']", "['the', 'sysop']",
  "['s', 'mystique']", "['had', 'been']", "['of', 'doom']",
  "['i', 'hooked']", "['in', 'california']", "['my', 'ego']",
  "['until', 'my']", "['didn', 't']"
]

The keys are formed by str() ,so it looks like list, but is a string. My question is, how can you separate each item to make it look like this?

[ 'my', 'modem', 'techenical', ... ]

Answer 1

Just do a pattern matching for each string:

res = []
for item in l:
    m = re.match("\['(.*)', '(.*)'\]", item)
    res.append(m.group(1))
    res.append(m.group(2))
#>>> res - ['my', 'modem', 'technical', ...]
