How can merge list value in a single list?

I have many files in a folder. I want to pick the latest file. I have written code also, but it is givving values in separate list.

Output I'm getting:

['tb_exec_ns_decile_20190129']
['tb_exec_ns_decile_20190229']
['tb_exec_ns_decile_20190329']

Expected Output:

['tb_exec_ns_decile_20190129', 'tb_exec_ns_decile_20190229', 'tb_exec_ns_decile_20190329']

Code:

path1 = "D:/Users/SPate233/Downloads/testing/*.csv"
files = glob.glob(path1)
print(files)

for name in files:
    new_files = []
    new_files = os.path.split(name)[1].split('.')[0]
    new_files = new_files.split(',')
    print(new_files)

You can always merge list in python as in example below:

>>> first_list = [1, 2, 3]
>>> second_list = [4, 5, 6]
>>> merged_list = first_list + second_list
>>> merged_list
[1, 2, 3, 4, 5, 6]

The correct term here would be append not merge since, you want all the file names in a list together, Create an empty list to store all the file names in it:

f_list = []                              # an empty list to store the file names
for name in files:
    file_name = os.path.split(name)[1].split('.')[0]
    f_list.append(file_name.split(','))  # appending the names to the list

print(f_list)                            # print the list
