Remove double quotes from the list ?

[PythonDev]

the problem you have is somewhere before the code you show here

i.e.
how it happened that cgi.FieldStorage instance

FieldStorage (None, None, [MiniFieldStorage ('v_name', 'John'), MiniFieldStorage ('v_sname', 'Aguiar')])

become a str

"FieldStorage (None, None, [MiniFieldStorage ('v_name', 'John'), MiniFieldStorage ('v_sname', 'Aguiar')])"

somewhere you converted cgi.FieldStorage object int str object and that is where the problem is.

there are appropriate methods to parse cgi.FieldStorage and acceess the MiniFiledStorage objects in the list and their values. Don't manipulate strings

import cgi
# let recreate what you SHOULD have instead of str
array_input = cgi.FieldStorage()
array_input.list = [cgi.MiniFieldStorage('v_name', 'John'), cgi.MiniFieldStorage('v_sname', 'Aguiar')]

# what we have and how we access data
print(type(array_input))
print(type(array_input['v_name']))
print(array_input.getvalue('v_name'))

Output:
<class 'cgi.FieldStorage'>
<class 'cgi.MiniFieldStorage'>

It all starts with the code below:

# Retrieves form field entries in the environment variable (wsgi.input) and assigns the variable (array_input):
array_input = cgi.FieldStorage(environ["wsgi.input"], environ=environ)

After that I send the variable array_input via parameter to the method of another class that processes deconstruction of the value of the variable (array_input) so that I can remove the characters that conflict in the threat detection (xss), because I don't know if it is possible to manipulate the type <class 'cgi.FieldStorage'> using regular expressions from the python re module, below is the code that receives the parameter and decouples the variable:

# Function -> Importa module cgi que trata form request e re (regex)
import re

# Class Function ->
class ProcessInputPost:

     # Method Function ->
     def spark (v_response, v_uri, array_input):

         # Function -> Convert to tuple
         a_inp = (array_input)
         # Function -> Convert tuple to string:
         o_inp = str(a_inp)
         # Function -> Remove parentheses for checking data:
         v_inp = re.sub ("[()]", "", o_inp)
         # Function ->
         from cern.safe.threatdetect import ThreatDetect
         # Function ->
         return ThreatDetect.m_post (v_response, v_uri, array_input)
