How to save multiple blender scripts (text-files) at once?

Question

I want to write a script that saves all the text files inside a Blender file. Is there a way I can access the text files as a list and then select them individually?

Heres my script so far:

import bpy
import datetime

file_destination = 'D:\\Sync Cloud\\Sync\\BLENDER PYTHON SCRIPTS\\Mass Saves By Date'

# GET SCRIPTS
all_scripts = bpy.data.texts
num_of_scripts = int((str(all_scripts).split('[')[1]).split(']')[0])

# GET DATE AND TIME
now = datetime.datetime.now()
date = str(now).split(' ')[0]
time = (str(now).split(' ')[1]).split('.')[0]

# GET BLENDER FILE NAME
path = str(bpy.data.filepath).split('\\')
file_path_num = len(path) - 1
file_name = path[file_path_num].split('.blend')[0]

i=0
for x in range(0,num_of_scripts):
    txt_script = bpy.data.texts[i]

    # DELETE A .py
    script_name = (str(txt_script).split("\"")[1]).split('.py')[0]
    if 'Text' not in script_name:

        py_filename = date +'_'+time+'_'+file_name+'_'+script_name+'.py'

        # SAVE SCRIPT
        bpy.ops.text.save_as(filepath=str(file_destination)+'\\'+str(py_filename),
        hide_props_region=True,
        check_existing=True,
        filter_blender=False,
        filter_backup=False,
        filter_image=False,
        filter_movie=False,
        filter_python=True,
        filter_font=False,
        filter_sound=False,
        filter_text=True,
        filter_archive=False,
        filter_btx=False,
        filter_collada=False,
        filter_alembic=False,
        filter_usd=False,
        filter_folder=True,
        filter_blenlib=False,
        filemode=9,
        display_type='DEFAULT',
        sort_method='FILE_SORT_ALPHA')

    i+=1

This keeps giving me an error:

Error: Unable to save '': Invalid argument Traceback (most recent call last): File "D:\Sync Cloud\Sync\BLENDER PYTHON SCRIPTS\Save Scripts.blend\Export Scripts.py", line 43, in File "C:\Program Files\Blender Foundation\Blender 2.82\2.82\scripts\modules\bpy\ops.py", line 201, in call ret = op_call(self.idname_py(), None, kw) RuntimeError: Error: Unable to save '': Invalid argument

Pathlib

Here is a script that writes all text files in blend with suffix .py to a designated folder.

IMO there is no need to timestamp a file name, since it is given a date when written to or touched. Timestamp a containing folder name if need be.

import bpy
from pathlib import Path

destination_folder = "/tmp/texts"
df = Path(destination_folder)

#create if doesn't exist
if not df.exists():
    df.mkdir(parents=True, exist_ok=True)

for text in bpy.data.texts:
    p = df / text.name
    if p.suffix == ".py":
        p.write_text(text.as_string())

On getting the path from the blend file name

>>> bpy.data.filepath
'/home/batfinger/Documents/blender/tests/snurf.blend'

>>> Path(bpy.data.filepath)
PosixPath('/home/batfinger/Documents/blender/tests/snurf.blend')

>>> bp = Path(bpy.data.filepath)

>>> bp.stem
'snurf'

If the file is new and has not been saved the datapath will be "". The folder will revert to the base path blender was started from. In my case blender was launched from the terminal in the folder "foo".

>>> dp = Path('')
>>> dp
PosixPath('.')

>>> dp.absolute()
PosixPath('/home/batfinger/foo')
