问题 I have a function which generates some variable, like score, right, wrong, unanswered. This function is called using a push button. The problem is how can I add/append these values generated by a function to an XLSX file every time? Or, how to create a MAT file so that it can be added? What may be a possible solution? 回答1: The challenge involved in appending to a xls file is knowing its last row, to avoid overwriting data with the xlswrite command. I'd suggest taking a look at this file

I have used poi to get the data, looks like you have used poi but not 100% sure. Below is the code that is working and reading all the values public static void main(String[] args) throws IOException {

问题 Fortify security run Noncompliant Code public static A read(String path) throws IOException, ClassNotFoundException { try (ObjectInputStream os = new ObjectInputStream(new GZIPInputStream(new FileInputStream(path)))) { return (A) os.readObject(); } } It is saying "Unreleased Resource: Streams" , but it is inside try-with-resource then what can be the issue? please help me. 回答1: Likely the issue your tool is worried about is if GZIPInputStream or ObjectInputStream throws an exception during

问题 The following example script writes some strings to a file using either "w" , text, or "wb" , binary mode: import itertools as it from string import ascii_lowercase import time characters = it.cycle(ascii_lowercase) mode = 'w' # mode = 'wb' # using this mode takes longer to execute t1 = time.clock() with open('test.txt', mode) as fh: for __ in xrange(10**7): fh.write(''.join(it.islice(characters, 0, 50))) t2 = time.clock() print 'Mode: {}, time elapsed: {:.2f}'.format(mode, t2 - t1) With

问题 I was using the below code to calculate the number of lines in a file. long numberOfLines = Files.lines(filePath).count(); Based on the output of the above, if the number of lines is 1, then the record delimiter (extracted from the last character of the line) should be replaced by <delimiter>\n . The delimiter got replaced fine, but when I tried to delete this file after this operation, it did not work. if (numberOfLines == 1) { String rawData = (new String(Files.readAllBytes(filePath))).trim

问题 So here is my import: from pyPdf import PdfFileWriter, PdfFileReader Here is were I write my pdf: filenamer = filename + '.pdf' pdf = PdfPages(filenamer) (great naming convention, I know!) I write some things to it. I close it here: pdf.close() Here is where I try and read it: input1 = PdfFileReader(file(filenamer, "rb")) And here is the error: Traceback (most recent call last): File "./datamine.py", line 405, in <module> input1 = PdfFileReader(file(filenamer, "rb")) TypeError: 'file' object

问题 I have been struggling to compress a regular string to ZSTD format using the Luben library (v1.4.0-1). I do the following: byte[] zstdBytes = Zstd.compress(payload.getBytes(StandardCharsets.UTF_8)); ZstdInputStream zstdInputStream= new ZstdInputStream(new ByteArrayInputStream(zstdBytes)); However while reading the zstdInputStream I get the following error: java.io.IOException: Decompression error: Unknown frame descriptor at com.github.luben.zstd.ZstdInputStream.readInternal(ZstdInputStream

问题 This should be so simple, it's silly. But I can't get it to work. I have a header which I define while reading a file: if "[gene=env]" in line or "[gene=HIV2gp7]" in line: header = line now this header looks something like ">lcl|NC_001802.1_prot_NP_057856.1_8 [gene=env]" I need to attach a number to it like so: ">lcl|NC_001802.1_prot_NP_057856.1_8 [gene=env]1" I have 100 identical headers, which have to be numbered 1 through 100 But whatever I try, I can't get the number on the same line.
