Invalid argument error when using f string in path of DataFrame.to_csv()

I want to write pandas dataframe to a csv file every 10 secs. The csv file name includes the current timestamp. Here is part of the code:
import pandas as pd
import time
while True:
df = pd.read_sql_query('select * from dbo.tbl_tag_values', cnxn)
t = time.localtime()
current_time = time.strftime('%Y-%m-%dT%H:%M:%S',t)
csv_path =f'C:/Users/00_Projects/App/data-{current_time}.csv'
df.to_csv(csv_path)
time.sleep(10)
Without using f-string and a static file name, the script works fine but with the f-string I get the error:
Traceback (most recent call last):
File "c:\Users\00_Projects\App\script.py", line 24, in <module>
df.to_csv(csv_path)
File "C:\ProgramData\Anaconda3\lib\site-packages\pandas\core\generic.py", line 3466, in to_csv
return DataFrameRenderer(formatter).to_csv(

File "C:\ProgramData\Anaconda3\lib\site-packages\pandas\io\common.py", line 702, in get_handle
handle = open(
OSError: [Errno 22] Invalid argument: 'C:/Users/00_Projects/App/data-2023-01-02T15:33:19.csv'
I read this post How to use f string in a path location and tried Path from pathlib but got the same error.
My OS is windows.
Thanks for any help!

How to open and close an excel workbook in a python for loop using xlwings

I need to open and close the same workbook in a python for loop without necessarily saving the workbook. I tried the following in xlwings:
import xlwings as xw
for i in range(5):
print(i)
book = xw.Book()
book.app.quit()
However this will only run for the first iteration. At the second iteration I get an error:
Traceback (most recent call last):
File "D:/TEMP/SE/python/ref.py", line 5, in <module>
book = xw.Book('tree_template.xlsx')
File "C:\Users\aboufira\AppData\Local\Continuum\miniconda3\envs\SE\lib\site-packages\xlwings\main.py", line 533, in __init__
for wb in app.books:
File "C:\Users\aboufira\AppData\Local\Continuum\miniconda3\envs\SE\lib\site-packages\xlwings\main.py", line 374, in books
return Books(impl=self.impl.books)

return Books(xl=self.xl.Workbooks)

File "_ctypes/callproc.c", line 948, in GetResult
OSError: [WinError -2147467259] Unspecified error
Why does this occur? How can I get xlwings to exit out of the application without causing any problems?

Your code was almost correct, use:
import xlwings as xw
for i in range(5):
print(i)
app = xw.App(visible=True)
book = xw.Book()
app.quit()
You can also use app = xw.App(visible=False) if you want to open a workbook without showing it.

Use this to suffice the pop-ups
app.display_alerts=False

Open .h5 file in Python

I am trying to read a h5 file in Python.
The file can be found in this link and it is called 'vstoxx_data_31032014.h5'. The code I am trying to run is from the book Python for Finance, by Yves Hilpisch and goes like this:
import pandas as pd
h5 = pd.HDFStore('path.../vstoxx_data_31032014.h5', 'r')
futures_data = h5['futures_data'] # VSTOXX futures data
options_data = h5['options_data'] # VSTOXX call option data
h5.close()
I am getting the following error:
h5 = pd.HDFStore('path.../vstoxx_data_31032014.h5', 'r')
Traceback (most recent call last):
File "<ipython-input-692-dc4e79ec8f8b>", line 1, in <module>

Unable to open/create file 'path.../vstoxx_data_31032014.h5'
where I have substituted my working directory for 'path.../' for the purpose of this question.
Does anyone know where this error might be coming from?

In order to open a HDF5 file with the h5py module you can use h5py.File(filename). The documentation can be found here.
import h5py
filename = "vstoxx_data_31032014.h5"
h5 = h5py.File(filename,'r')
futures_data = h5['futures_data'] # VSTOXX futures data
options_data = h5['options_data'] # VSTOXX call option data
h5.close()

import os
wd=os.chdir('pah of your working directory') #change the file path to your working directory
wd=os.getcwd() #request what is the current working directory
print(wd)
if __name__ == '__main__':
# import required libraries
import h5py as h5
import numpy as np
import matplotlib.pyplot as plt
f = h5.File("hdf5 file with its path", "r")
datasetNames = [n for n in f.keys()]
for n in datasetNames:
print(n)

Unable to open xlsx file with xlrd

I am getting an error file is not support in xlrd-0.7.1.
The file is saved in xlsx format
Traceback (most recent call last):
File "C:\Users\jawed\workspace\test\Excelproject.py", line 8, in <module>
workbook=xlrd.open_workbook(file_location)
File "C:\Python27\lib\site-packages\xlrd\__init__.py", line 425, in open_workbook

File "C:\Python27\lib\site-packages\xlrd\__init__.py", line 878, in biff2_8_load
f = open(filename, open_mode)
IOError: [Errno 2] No such file or directory: 'C:\\Users\\jawed\\workspace\\IAMarks.xls'

The file doesn't exist.
Check the location of the file before calling the function:
import os
if os.path.isfile(file_location):
workbook = xlrd.open_workbook(file_location)
else:
# tell the user they've done something wrong
A possibly more Pythonic way to do it (see EAFP) is in a try/except block:
try:
workbook = xlrd.open_workbook(file_location)
except IOError as error:
print(error)
# tell the user they've done something wrong

write to an open exceldocument

I'm working on a project which I am going to write values to a exceldocument. I can write values to excel but I want to write the values to excel with the document open. If i have the doc open when trying to write to it i get an error message.
Here is my code I'm currently using.
#Write to excel
from openpyxl import Workbook
import datetime
wb = Workbook()
ws = wb.active
ws['C3'] = 1337
ws['A1'] = datetime.datetime.now()
ws['B5'] = CIRCLES
ws['B4'] = "Red puck"
wb.save("sample.xlsx")
And the error message when i have the doc. opened when trying to write to it.
