我正在尝试使用new SimpleDateFormat来解析dd-MM格式的字符串。基本上,我想从字符串中创建一个日期对象并保留在数据库中。
当我检查数据库条目时,我看到它将1970追加到year列。我相信这是空时提供的年份的默认值。有没有一种方法可以防止年份值。我不想存储有关年份的信息。
我的代码-
String dateOfBirth = "14-Feb";
dbObject.save(new SimpleDateFormat("dd-MMM").parse(dateOfBirth));

为了简单起见,假设dbObject.save()该方法期望提供日期对象。我不想创建一个值的日期-1970年2月14日,相反它应该只是14年2月。
I'm using this code to apply a function (funcX) on my data-frame using a rolling window. The main issue is that the size of this data-frame (data) is very large, and I'm searching for a faster way to do this task.
import numpy as np
def funcX(x):
x = np.sort(x)
xd = np.delete(x, 25)
med = np.median(xd)
return (np.abs(x - med)).mean() + med
med_out = data.var1.rolling(window = 51, center = True).apply(funcX, raw = True)

I am trying to create rows in a DIV where there are three pieces of information to display. A left align text, a right align text, and repeat character "." between the two
I tried this using the HTML below. But it is not working with a div for each piece.
<div style="margin-bottom:5px"><!-- row 1 -->
<div style="float:left;">Left</div> <!-- left column -->
<div style="display: inline-block;">...</div> <!-- center column -->
<div style="float:right;">Right</div> <!-- center column -->
</div><!-- row 1 -->
