You can use this code:

res = ['-14.82381293', '-0.29423447', '-13.56067979', '-1.6288903']
res=map(str, res)
print ('[%s]' % ','.join(map(str, res)))

This code is used for string or Integer or a decimal number for example:

res = ['-14.82381293', '-0.29423447', '-13.56067979', '-1.6288903','book','3234']

In your case, the elements are stored as strings in the list res.
You have to convert those elements into numbers.

In this situation python's builtin map(...) function can be used.
Syntax of map:

variable_to_store_new_value = map(type, list_of_elements)

Above code will return a map object. Convert that into a list.

variable = list(map(type, list_of_elements))

Here type can be any valid python data type (str, int, float, etc.) or a function.

Solution to your problem

res = list(map(float, res))

what says float about it?

res = [float(item) for item in res]
print(res)

honestly, have not seen the answer in comments

The quotes are coming because the numbers are stored as string data type.

Therefore to remove the quotes, you must convert them into float.

res = ['-14.82381293', '-0.29423447', '-13.56067979', '-1.6288903']
new_res=[]
for i in range(0,len(res)):
    new_res.append(float(res[i]))
print(new_res)

You can do this .
