Python3: Wanna have a date ? Python has a date and time for you!

Let's see one of the widely used python modules - datetime

A basic example of datetime:

We need to convert the datetime objects to string in the required format so that they can be user-readable. This is how we can do that:

There are following directives which you can use to format the date:

%d - Day of the month (01-31) %m - Month as number (01-12) %b - Short version of month (e.g. Mar) %B - Full version of Month name (e.g. March) %a - Short version of weekday (e.g. Wed) %A - Full version of weekday (e.g. Wednesday)

%w - Weekday as number 0-6 and 0 is Sunday. %Y - Full version of year (e.g 2021)

%y - Short version of year (e.g. 21) %I - Hour ranging 00-12

%H - Hours ranging 00-23 %p - AM/PM %M - Minutes ranging 00-59 %S - Seconds ranging 00-59 %f - Microseconds ranging 000000-999999

%j - Day number of year ranging 001-366

From the frontend we will get the dates as strings to operative over them we will need them to convert to the python's native datetime type.

Let's try some other date format:

Get today's date:

Some examples of datetime.time module to access time and it's conversions:

We often need to calculate date from future or in the past in the real world. Let's how we can calculate that:
