Convert ISO 8061 datetime to timestamp in python - python

I have a string with a date in the format: 2021-03-12T14:45:34.000Z
I would like to convert it to a standard format as this one: 12-Mar-2021 14:45:34
I tried using:
print(datetime.datetime.strptime("2021-03-12T14:45:34.000Z", "%Y-%m-%dT%H:%M:%S%fZ"))
but I get the error:
ValueError: time data '2021-03-12T14:45:34.000Z' does not match format
'%Y-%m-%dT%H:%M:%S%fZ'
How can I solve it?


You need to get as datetime then convert to forrmat as you like:
import datetime
date = '2021-03-12T14:45:34.000Z'
datetime.datetime.strptime(date, "%Y-%m-%dT%H:%M:%S.%fZ"
).strftime('%d-%b-%Y %H:%M:%S')
Output:
'12-Mar-2021 14:45:34'


You are missing a . in your format string. The correct format string is
"%Y-%m-%dT%H:%M:%S.%fZ"
Notice the . after %S and before %fZ.

Convert Dates pandas datetime

I'm trying to convert dates in the format '31-Aug-91' into '31-08-1991' using pandas datetime.
I've tried pd.to_datetime(df['INCIDENT_DATE'], format = '%d-%m-%y').dt.date
But, I get the error ValueError: time data '31-Aug-91' does not match format '%d-%m-%y' (match)
How do I fix this?

Use %b for match first 3 letters of month names:
pd.to_datetime(df['INCIDENT_DATE'], format = '%d-%b-%y').dt.date
If need format DD-MM-YYYY:
pd.to_datetime(df['INCIDENT_DATE'], format = '%d-%b-%y').dt.strftime('%d-%m-%Y')

How can I convert a string like 3hours26minutes33seconds into HH:MM:SS format in python?

I have a string '3hours26minutes33seconds' and I need to convert this into HH:MM:SS format.
I tried using dateutil.parser.parse to no avail.

You can use datetime and its strptime function to convert it to a datetime object:
import datetime
string = "3hours26minutes33seconds"
date = datetime.datetime.strptime(string, "%Hhours%Mminutes%Sseconds")
Then you format that datetime into the desired string format with strftime:
date.strftime("%H:%M:%S")

There is a string and a date format. I want to get the date based on format.
