问题 I need to count business days between two dates. In addition, I must also remove the days listed in a separate table (holidays). So far I have this code. It counts the days but does not remove the days from the separate table (holidays). class Holidays(models.Model): class Meta: ordering = ['date'] date = models.DateField(null=True, verbose_name='Date') class Situation(models.Model): class Meta: ordering = ['date_time_start'] date_time_start = models.DateTimeField(null=True, blank=False,

问题 I have some missing dates in a file. e.g. $cat ifile.txt 20060805 20060807 20060808 20060809 20060810 20060813 20060815 20060829 20060901 20060903 20060904 20060905 20070712 20070713 20070716 20070717 The dates are in the format YYYYMMDD. My intention is fill the missing dates in between the dates if they are missing maximum for 5 day e.g. 20060805 20060806 ---- This was missed 20060807 20060808 20060809 20060810 20060811 ----- This was missed 20060812 ----- This was missed 20060813 20060814

问题 The title is pretty straight forward - how can I calculate the difference between the largest and smallest value column-wise, for each row? Let's assume this is my data: a b c d 1 2 3 4 0 3 6 9 3 2 1 4 9 8 7 6 For each row, I want to find the difference between the column with the highest value and the column with the lowest value - the result looks like this: 3 9 3 3 Any help is greatly appreciated! 回答1: 1 For each row (using apply with MARGIN = 1 ), use range to obtain a vector of the

问题 I want to know the difference between contact card and contactless(RF) card in terms of APDU command/response, implementation and so on. I'm implementing an applet using combi card. I thought that regardless of contact interface or contactless(RF) interface, an applet returns the same response APDU for a command but it doesn't seem like that. I have no idea about that. (I implemented an applet for the only RF interface or for the only contact interface before, not for both.) Is it possible to
