However, my requirement is to have consistent fixed length o/p like #1.) expected java ZonedDateTime o/p --> 2011-01-19T04:00:00.000000Z[UTC] However, I didnt find any date

问题 If you could help me understand why: From Cygwin terminal: This is correct: $ date Wed, Sep 2, 2020 11:19:07 PM This is also correct: $ date --utc Wed, Sep 2, 2020 9:19:14 PM Timezone is also correct: $ echo $TZ Europe/Zurich But when ask for local time in Python3 from the same Cygwin terminal it shows this: $ python Python 3.8.5 (tags/v3.8.5:580fbb0, Jul 20 2020, 15:57:54) [MSC v.1924 64 bit (AM D64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from

问题 I have a script that outputs to CSV all items/files from all Lists and Libraries. In addition, it displays the current and previous versions of an item/file. This also displays which user modified the file for each version and also displays the date/time the file was modified for every version: function Get-DocInventory([string]$siteUrl) { $web = Get-SPWeb "http://contoso.com/sites/Depts3/HBG" foreach ($list in $web.Lists) { foreach ($item in $list.Items) { foreach($version in $item.Versions)

问题 I have a timestamp string that looks like this: 2019-02-16T10:41:20.6080000+01:00 I have to parse it to datetime. Because there are 7 instead of 6 digits for microseconds the following format does not match: timestamp = "2019-03-14T14:37:37.000000+01:00" parsed_timestamp = datetime.datetime.strptime(timestamp, "%Y-%m-%dT%H:%M:%S.%f%z") #ValueError: time data '2019-03-14T14:37:37.0000000+01:00' does not match format '%Y-%m-%dT%H:%M:%S.%f%z' How can I parse this format? 回答1: Using dparser:

问题 So I have the following code which reads in 5 columns, date ohlc. It then creates a column 'dow' to hold day of week. So far so good: import numpy as np import pandas as pd df = pd.read_csv('/content/drive/MyDrive/Forex/EURUSD-2018_12_18-2020_11_01.csv',parse_dates=True,names = ['date','1','2','3','4',]) df['date'] = pd.to_datetime(df['date']) df.index = df['date'] df['dow'] = df['date'].dt.dayofweek #df['downum'] = df.apply(lambda x: downu(x['date'])) df Producing the following output: date

问题 I need: XX:01 through XX:14 to round down to XX:00 XX:15 through XX:29 to round up to XX:30 XX:31 through XX:44 to round down to XX:30 XX:45 through XX:59 to round up to (XX+1):00 Notes: I gave only two cases in the code, ultimately I have more of them For example, I added additional inputs in the code that are not used, they are not valid They must check automatically if it has been entered.
