format

问题 I'm trying to display a date using the date action, but it's giving odd output. {{ mydate | date:'mm/dd/yyyy' }} The month seems to be inconsistent and incorrect. What's wrong here? 回答1: You need to use MM to display the month: {{ mydate | date:'MM/dd/yyyy' }} From the documentation 'MM': Month in year, padded (01-12) ... 'mm': Minute in hour, padded (00-59) 回答2: You need to use date:'MM/dd/yyy' mm is for minutes, MM is for months 来源： https://stackoverflow.com/questions/27584890/angular-date

问题 I'm having issues with using the @DateTimeFormat Spring annotation. I've been researching a bit about it today, but for some reason I just can't get it to work. @DateTimeFormat(pattern="MM/dd/yyyy") @Column(name="my_date") private Date myDate; public Date getMyDate() { return this.myDate; } public void setMyDate(Date myDate) { this.myDate = myDate; } Right now the code is displaying the date and time as yyyy-MM-dd HH:mm:ss.S (i.e. 2012-01-11 00:00:00.0) I read that you need Joda-Time added to

问题 I need to write the common queries for MySQL and Oracle databases. Problem occurs when I have to put date conditions. For example: there is one field Txn_date which is in format of '20150116' in MySQL and '16-JAN-2015' in Oracle. I use date_format(now(),'%Y%m%d') for MySQL and to_char(sysdate,'dd-MON-YYYY') for Oracle. Is there any common function of way by which I can use the same function in both Oracle and MySQL? I tried Txn_date in ( date_format(now(),'%Y%m%d') OR to_char(sysdate,'dd-MON

问题 I'm trying to write a list to rows with a specific number of columns. For example, take the list: data = [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0] I would like to write this out with a format such that it looks like: 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, I've tried the following code; however, can only get it to print the first line: strformat = ['{'+str(i)+':>5.1f},' for i in range(0,3)] strformat = ''.join(strformat).lstrip().rstrip() + '\n' print strformat.format(*[x

问题 This code gives an error print('type a whole number:') n = input() if n % 2 == 1: print('Odd'); else: print('Even'); I'm assuming there's something special I have to do to variable n in the if statement? I am a beginner to Python. 回答1: Here is how to fix it: n = int(input("type a whole number:")) Since input() returns a string, you need to convert it to an int first, using int(). 回答2: You need to convert n to an integer first, in py 3.x input() returns a string.: n = int(input()) 回答3: Convert

问题 I put .describe() to a Dataframe, the output doesn't look nice. I want the output to show the whole number and not be simplified with exponentials. Input: df["A"].describe() How the output looks like: count 6.000000e+01 mean 7.123568e+04 std 2.144483e+05 min 1.000000e+02 25% 2.770080e+03 50% 1.557920e+04 75% 4.348470e+04 max 1.592640e+06 Name: A, dtype: float64 Expected Output: count 60.0 mean 7123.568 std 214448.3 min 100.0000 25% 2770.080 50% 15579.20 75% 43484.70 max 1592640.0 Name: A,

问题 I have two devices working in paralell, the problem is that one of them was set up 12 hours different than the other (that is, instead of 17:00, marked 05:00). I'm trying to apply this solution: How to read 12h (AM/PM) timeformat in gnuplot In this way: My data are like this: #Time Concentration (#/cm³) 05:00:14 5902 05:00:15 5898 05:00:16 5989 05:00:17 5921 And I'm running the folowing code: set xdata time set timefmt '%H:%M:%S' set format x '%H:%M' set xlabel "time" plot "< awk '{time = $1;

问题 I'm debugging a perl script which looks like this (simplified): #!/usr/bin/perl use strict; use warnings; use Evil::Module; printf "%.3f\n", 0.1; This script outputs 0,100 (note , instead of . ). If I comment out the use Evil::Module statement, the output will be 0.100 . I believe that this is related to locale setting in the module. But locale is a lexical pragma (according to the manpage), and it's not used within the script. What's happening here? 回答1: The use locale pragma is lexical, but

问题 I'm a bloody beginner to Fortran (f90) and some apparently easy problems turn out to cause severe headaches...Thanks for helping me with this one: My code runs through a loop, processes data and writes them into a file. I'd like to have those data written in columns of the same file until the looping is finished. OPEN (unit=11,file=filename // '.csv') WRITE(11,'(i4,A1,f10.6)') NUM4 , tab, NUMfloat10_6 CLOSE(11) This code works fine for the saving of a single dataset. "tab" is defined as char

问题 I want to create a text field that will be for dates and will have dd.mm.YYYY format. Now what I want the user to type only the numbers, not the dots to. So the field would be like: _ _. _ _ . _ _ _ _ So when the user wants to type the date: 15.05.2010 for example, he will only type the numbers in the sequence 15052010. Also I would like, when he presses on left or right arrow, the cursor to go from one field (not JTextField, but field in the JTextField) to the next. So lets say I have
