How to convert a tuple in a list to a normal list?

Use tuple unpacking

response = [('indigo', 'admin')]
data = [*response[0]]
print(data)

Output: ['indigo', 'admin']

For this very specific example you can just access the first element of the list a = [('indigo', 'admin')] via your_tuple = a[0] which returns your_tuple = ('indigo', 'admin'). Then this tuple can be converted to a list via list(your_tuple).

In general it is better not to do these steps in between. I just put them to be more pedagogical. You get the desired result with:

list(a[0])

you can access the first elem of the origin list [('indigo', 'admin')] (it has only one elem) to get the tuple. then use list function to convert the tuple into list.
