string-formatting

问题 I have a date in this format 10/12/2011 12:55:00 PM (MM-DD-YYYY time) I would like to format this date into 12/10/2011 (DD-MM-YYYY) time to be removed using XSLT? the complexity I find is sometimes the input date can look like 7/12/2011 12:55:00 PM (only one number to the front instead of 07) Can someone please show me a way to implement this? many thanks in advance. 回答1: It is easy to obtain desired result using only standard XPath string functions like substring-before , substring-after and

问题 https://en.wikipedia.org/wiki/International_Bank_Account_Number#Practicalities The IBAN should not contain spaces when transmitted electronically: when printed it is expressed in groups of four characters separated by a single space, the last group being of variable length as shown in the example below: A typical IBAN looks like this: GR16 0110 1250 0000 0001 2300 695 (taken from the above link). I want to make it easier for users to enter IBAN numbers. Currently I use a TDBEdit to display

问题 I am trying to write a string format that will round or pad numbers to two decimal places, and also display negative numbers with brackets around them. This is in a in a WPF application, but it applies to any .net StringFormat use case. For example: 2.0 -> 2.00 -2.0 -> (2.00) 0.01 -> 0.01 -0.01 -> (0.01) 0.001 -> 0.00 -0.001 -> (0.00) The last one, a very small negative number rounded to zero, is the problem. I still want the brackets to indicate that it was negative. My first version was a

问题 How to convert int (4 bytes) to hex (" XX XX XX XX ") without cycles? for example: i=13 hex="00 00 00 0D" i.ToString("X") returns "D" , but I need a 4-bytes hex value. 回答1: You can specify the minimum number of digits by appending the number of hex digits you want to the X format string. Since two hex digits correspond to one byte, your example with 4 bytes needs 8 hex digits. i.e. use i.ToString("X8") . If you want lower case letters, use x instead of X . For example 13.ToString("x8") maps

问题 Python Version 3.5 I'm trying to make an API call to configure a device using json as the format. Some of the json will vary depending on the desired naming, so I need to call a variable in the string. I am able to accomplish this using the old style %s... % (variable) , but not with the new style {}... .format(variable) . Failed EX: (Testing with {"fvAp":{"attributes":{"name":(variable)}}}) a = "\"app-name\"" app_config = ''' { "fvAp": { "attributes": { "name": {} }, "children": [ { "fvAEPg"

问题 Is it possible to capitalize a word using string formatting? For example, "{user} did such and such.".format(user="foobar") should return "Foobar did such and such." Note that I'm well aware of .capitalize() ; however, here's a (very simplified version of) code I'm using: printme = random.choice(["On {date}, {user} did la-dee-dah. ", "{user} did la-dee-dah on {date}. " ]) output = printme.format(user=x,date=y) As you can see, just defining user as x.capitalize() in the .format() doesn't work,

问题 As the title states, what is the difference between these two flags? It seems they both convert the value to a string using repr()? Also, in this line of code: "{0!r:20}".format("Hello") What does the 0 in front of the !r do? 回答1: %r is not a valid placeholder in the str.format() formatting operations; it only works in old-style % string formatting. It indeed converts the object to a representation through the repr() function. In str.format() , !r is the equivalent, but this also means that
