Introduction:
The ‘datetime’ module in python is a powerful tool for handiling date and time. It provides classes for manipulating dates. It enters a python expression enrichment to convert dates from one format to another . In this we use some expressions :
- Convert a date from YYYY-MM-DD to MM-DD-YY
- parse the original date string into ‘datetime’object.
- Format the ‘date’ object into the desired string format.
parding the date string:
- ‘datetime.striptime(date_str, “%Y-%m-%d)’: now this function Parses the date string(‘date_str’) using the formate’”%Y – %m – %d”‘.the format codes are:
`%Y`:Four-digit year`%m`: Two-digit year`%d`: Two-digit day
formatting the `datetime` Object:
date_obj.strftime("%d-%m-%Y"):this function converts the`datetime` object(`date_obj`) back into sting using the new format`"%d-%m-%Y"`. the format codes are:`%d`: Two-digit day`%m` : Two-digit month
`%Y` : Four-digit year
example:
import datetime
date_input = '20190707'
datetime_object = datetime.datetime.strptime(date_input, '%Y%m%d')
new_format = datetime_object.strftime('%m-%d-%Y')
new_format_1 = datetime_object.strftime('%m/%d/%Y')
print(new_format)
print(new_format_1)
Output:
07-07-2019
07/07/2019

conclusion :
Changing date formats in Python is essential for data cleaning and ensuring consistency across different systems. The datetime module offers a robust and flexible approach to handle these conversions effectively. By understanding and utilizing strptime for parsing and strftime for formatting, you can easily convert date strings between various formats as required for your applications.
