Convert pyspark string to date format
(6 answers)
Closed 5 months ago.
I have a column of dates in a pyspark dataframe in the format 01-01-1999 (dd-mm-yyyy)and I would like to change the date format of the entire column to 1999-01-01 (yyyy-mm-dd). Any help?
In pyspark we have this function:
date_format(dateExpr,format)
It converts a date/timestamp/string to a value of string in the format specified by the date format given by the second argument.
You can try ths one:
df.select(date_format('your_column_date', "yyyy-MM-dd")).show()

How to change the datetime format in Pandas
(8 answers)
Closed last month.
I have a DataFrame with a str column of dates like
'time': '2018-02-25T08:00:00.000Z'
but when applying pd.to_datetime to that column, the output looks like
'time': '2018-02-25 08:00:00+00:00'
Why is the format changing? I tried
pd.to_datetime(utc = True)
and
pd.to_datetime(..., format='%Y-%m-%dT%H:%M:%S.%f%z')
but none of them seem to work and the format gets changed.
Following #roganjosh comments, I converted it back to string with
df['time'].dt.strftime('%Y-%m-%dT%H:%M:%S.000Z')

I have a date say - 25-Jan-19
I want to convert it to - Jan19 in python. What date format I'll have to use to get this?
If 25-Jan-19 is a string and will always be in this format, you can try this:-
date = date.split("-")
date = "".join(date[i] for i in range(1,len(date)))

Pandas Timedelta in Days
(5 answers)
Closed 3 years ago.
So, I have a pandas dataframe with a lot of variables including start/end date of loans.
I subtract these two in order to get their difference in days.
The result I get is of the type i.e. 349 days 00:00:00.
How can I keep only for example the number 349 from this column?
Check this format,
df['date'] = pd.to_timedelta(df['date'], errors='coerce').days
also, check .normalize() function in pandas.
