How do I import this timestamp, and then get days since the timestamp?

I am receiving a timestamp as a string in this format 2024-09-27T04:58:04.894614Z

I've done a lot of playing and reading around using import datetime, converting to datetime objects

e.g. timestamp = datetime.strptime(timestamp, '%Y-%m-%d %H:%M:%S.%f')

But datetime seems extremely confusing to use.

I am current using

from datetime import datetime, date, time, timedelta which cannot be changed.

How can I get the number of days since the imported timestamp please?

Keep it simple,

• Parse the string to a datetime object using strptime.
• Use datetime.now() to get the current time.
• Subtract the parsed datetime from the current time and extract the days from the result.

from datetime import datetime

timestamp = "2024-09-21T04:58:04.894614Z"
timestamp_dt = datetime.strptime(timestamp, '%Y-%m-%dT%H:%M:%S.%fZ')
now = datetime.now()
difference = now - timestamp_dt
days_since = difference.days

You can also use fromisoformat, as suggested by Mark Tolonen:

timestamp_dt = datetime.fromisoformat(timestamp.rstrip("Z"))

Note that the date format is wrong also, the correct one should be:

%Y-%m-%dT%H:%M:%S.%fZ
