用python代码，列表格式的文本文件，我们想转换为hcl格式的terraform。用expected格式，它无法添加双引号“”与列表。
下面是列表文件input.txt

spn-owner-adm = owner, reader, admin, net-admin, str-admin, viewer
spn-net-adm = admin, net-admin, str-admin
spn-str-adm =  str-admin, viewer, compute-admin, viewer, reader
spn-my-adm = owner, admin, viewer, reader

预期输出. txt

spn-owner-adm = [ "owner", "reader", "admin", "net-admin", "str-admin", "viewer" ]
spn-net-adm = [ "admin", "net-admin", "str-admin" ]
spn-str-adm = [ "str-admin", "viewer", "compute-admin", "viewer", "reader" ]
spn-my-adm = [ "owner", "admin", "viewer", reader" ]

output.txt文件错误，每个字符用双引号引起来。

spn-owner-adm  = [" ""o""w""n""e""r"","" ""r""e""a""d""e""r"","" ""a""d""m""i""n"","" ""n""e""t""-""a""d""m""i""n"","" ""s""t""r""-""a""d""m""i""n"","" ""v""i""e""w""e""r" ]
spn-net-adm  = [" ""a""d""m""i""n"","" ""n""e""t""-""a""d""m""i""n"","" ""s""t""r""-""a""d""m""i""n" ]
spn-str-adm  = [" "" ""s""t""r""-""a""d""m""i""n"","" ""v""i""e""w""e""r"","" ""c""o""m""p""u""t""e""-""a""d""m""i""n"","" ""v""i""e""w""e""r"","" ""r""e""a""d""e""r" ]
spn-my-adm  = [" ""o""w""n""e""r"","" ""a""d""m""i""n"","" ""v""i""e""w""e""r"","" ""r""e""a""d""e""r" ]

#!/usr/bin/env python3
import re
myspn_pattn = r"""^spn-.*-adm.*$"""
spnup = []
myfile = "input.txt"
with open(myfile, 'r') as fsp, open('output.txt', 'w+') as fspn:
    fspn.write("spn =   {" "\n\n")
    for myspn in fsp:
        spnmatch = re.findall(myspn_pattn, myspn)
        if spnmatch:
            for line in spnmatch:
                spnname = line.split('=')[0]
                spnrglist = line.split('=')[1]
                #print("\t" '{} = "{}",' .format(spnname, spnrglist))
                spnup = '{} = [{} ]\n'.format(spnname, ''.join(['{}'.format(v) for v in spnrglist]))

            fspn.write(spnup)
    fspn.write("\n")
    fspn.write("\t" "}")

regex

由于sprnglist是一个字符串，执行for v in sprnglist会遍历字符。话虽如此，我无法复制您描述的每个字符都有引号的问题，但代码示例的输出无论如何都不是预期的结果。
如果你想得到想要的输出，你首先需要将字符串分割成你想要的部分（每个部分都用,分割），然后用引号括起来，然后重新连接它。在下面的例子中，我用,连接它以用于输出格式。

import re
myspn_pattn = r"""^spn-.*-adm.*$"""
spnup = []
myfile = "input.txt"
with open(myfile, 'r') as fsp, open('output.txt', 'w+') as fspn:
   fspn.write("spn =   {" "\n\n")
   for myspn in fsp:
      spnmatch = re.findall(myspn_pattn, myspn)
      if spnmatch:
         for line in spnmatch:
            line:str
            spnname = line.split('=')[0]
            spnrglist = line.split('=')[1]
            #print("\t" '{} = "{}",' .format(spnname, spnrglist))
            spnup = '{} = [{} ]\n'.format(spnname, ', '.join(['"{}"'.format(v.strip()) for v in spnrglist.split(",")]))

         fspn.write(spnup)
   fspn.write("\n")
   fspn.write("\t" "}")

我还想指出的是，使用fspn.write("\t" "}")会导致输出中出现奇怪的缩进。
output.txt:

spn =   {

spn-owner-adm  = ["owner", "reader", "admin", "net-admin", "str-admin", "viewer" ]
spn-net-adm  = ["admin", "net-admin", "str-admin" ]
spn-str-adm  = ["str-admin", "viewer", "compute-admin", "viewer", "reader" ]
spn-my-adm  = ["owner", "admin", "viewer", "reader" ]

    }
