What would be the best (fastest, nicest looking code) to do this? I've done this in c++ and did something like this: uint8_t *buffer; uint32_t value = buffer[0] | buffer[1] << 8 | buffer[2] << 16 | buffer[3] << 24; But in Java this causes a problem if for example buffer[1] contains a value which has it sign bit set as the result of a left-shift is an int (?). Instead of OR:ing in only 0xA5 at the specific

I'm using csvreader and csvwriter to get as far as I have. I've only figured out how to write them to rows using csvwriter.writerow. 回答1: It sounds like you have tried: values = [1, 2, 3, 4, 5] thecsv = csv.writer(open("your.csv", 'wb')) thecsv.writerow(values) Perhaps you should try: values = [1, 2, 3, 4, 5] thecsv = csv.writer(open("your.csv", 'wb')) for value in values: thecsv.writerow(value) 文章来源: Convert Python List to Column in CSV

The ability to convert from a cpp_int to a fixed-width floating-point type (i.e., a cpp_dec_float_50 ) gives one hope

When I do it with my react native mobile app, it passes the date as a moment object and it doesn't get converted to a string and it doesn't work. Is there a way to convert the moment object into a plain string like "Tue May 05 2015 23:59:59 GMT+0800 (HKT)" I tried toString() and toUTCString() and it doesn't work. Thanks. 回答1: Use moment().format() to

Not only do I not completely understand the method (there are no comments) but also the article implies that in future there will be better methods. If this is the best method, could you please point out what makes it work, and if not I would like to hear suggestions for better methods. 回答1: mbstowcs() and wcstombs() don't necessarily convert to UTF-16 or UTF-32, they convert to wchar_t and whatever the locale wchar_t encoding is.
