Prerequisite: DateTime module
In this article, we are going to see how to create filenames with dates or times using Python.
For this, we will use the DateTime module. First, import the module and then get the current time with datetime.now() object. Now convert it into a string and then create a file with the file object like a regular file is created using file handling concepts in Python.
Example 1: Creating text file containing date/time
Python3
# import modulefrom datetime import datetime# get current date and timecurrent_datetime = datetime.now().strftime("%Y-%m-%d %H-%M-%S")print("Current date & time : ", current_datetime)# convert datetime obj to stringstr_current_datetime = str(current_datetime)# create a file object along with extensionfile_name = str_current_datetime+".txt"file = open(file_name, 'w')print("File created : ", file.name)file.close() |
Output:
Current date & time : 2023-05-11 07-21-36 File created : 2023-05-11 07-21-36.txt
Any type of file can be created in this manner if the required extension is provided correctly.
Example 2: Creating CSV file containing date/time
Python3
# import modulefrom datetime import datetime# get current date and timecurrent_datetime = datetime.now().strftime("%Y-%m-%d %H-%M-%S")print("Current date & time : ", current_datetime)# convert datetime obj to stringstr_current_datetime = str(current_datetime)# create a file object along with extensionfile_name = str_current_datetime+".csv"file = open(file_name, 'w')print("File created : ", file.name)file.close() |
Output:
Current date & time : 2023-05-11 07-22-34 File created : 2023-05-11 07-22-34.csv
