问题 I want to convert a date by the following statement $date=date('d M Y, H:m',strtotime($date)); It printed out 09 Sep 2012, 11:09 when I tried various values of $date: 11:00 AM Sunday, 09 Sep 2012 Sunday 09 Sep 2012, 11:00 AM 09 Sep 2012 11:00 AM What date format does the strtotime() function need?

问题 I store some data in a database and I read those data with a cursor. All the data are 56.45 , 3.04, 0.03 type, so two numbers after the decimal point.

问题 I'm running the following code: asset = {} asset['abc'] = 'def' print type(asset) print asset['abc'] query = '{"abc": "{abc}"}'.format(abc=asset['abc']) print query Which throws a KeyError error: [user@localhost] : ~/Documents/vision/inputs/perma_sniff $ python ~/test.py <type 'dict'> def Traceback (most recent call last): File "/home/user/test.py", line 5, in <module> query = '\{"abc": "{abc}"\}'.format(abc=asset['abc']) KeyError: '"abc"' Format is obviously getting confused by the wrapping

问题 I have a file where each line is a set of results collected in specific replicate of an experiment. The number of results in each experiment (i.e. number of columns in each row) may differ. There's also no importance to the order of the results in each row (the first result in row 1 and the first result 2 are not more related than any other pair; these are sets of results). The file looks something like this: 2141 0 5328 5180 357 5335 1 5453 5325 5226 7 4880 5486 0 2650 0 5280 4980 5243 5301

问题 I am new to IPhone development. I need to take the current date from device and send to a server in JSon format. The server expects this date to be in milliseconds as since January 1, 1970, 00:00:00 GMT(Unix time) . I have noticed IPhone has some methods to get the current time in SECONDS, well, should be very easy to transform seconds to milliseconds with a simple * 1000 routine. All the problem begins because as this is my first lines of code with Objective-C for IPhone I am lost trying to

Is it possible to format the following number to Year-Month I entries as follows: 1402 1401 1312 Meaning February 2014. January 2014 and December 2013.

问题 I have a cobol "tape format" dump which has a mixture of text and number fields. I'm reading the file in C# as a binary array (array of byte). I have the copy book and the formats are lining up fine on the text fields. There are a number of COMP-3 fields as well. The data in those fields doesnt seem to match any BCD format. I know what the data should be and I have the raw bytes of the COMP-3. I tried converting to EBCDIC first which yielded no better results. Any thoughts on how a COMP-3
