问题 $formatthis = 219; $printthis = 98; // %c - the argument is treated as an integer, and presented as the character with that ASCII value. $string = 'There are %c treated as integer %c'; echo printf($string, $formatthis, $printthis); I'm attempting to understand printf(). I don't quite understand the parameters. I can see that the first parameter seems to be the string that the formatting will be applied to. The second is the first variable to format, and the third seems to be the second

问题 i wanted to convert a binary number to a decimal in assembly but i keep on getting zero this is the number aLength db "00000000000000000000000000010101", NULL and i tried using this code to get each character and subbing by '0' multiplying by 2 and adding but it keeps saying that the answer is 0 mov rbx,aLength mov dword[rsum],0 mov ecx,0 mov r10,32 lp: mov cl,byte[rbx] sub cl,'0' mov eax,dword[rsum] mul dword[two] add eax,ecx mov dword[rsum],eax add rbx,1 dec r10 cmp r10,0 jbe lp mov r8d

问题 For Asembly (68hc11) This is an assigment to handle in paper. Write a program to convert a 16-bit integer unsigned number into an ASCII string representing the number in hexadecimal. The number is in register D0 and the string is in put in memory starting at the address in register A0. How can i separated the bit number into 4 bits to represent the hex number in assembly, is there an instruction for doing this? I have a problem to visualize the logic of the program, also. After separated the

问题 I am trying to write a function that will receive an ascii key and will convert it to a Virtual-key-code. Ex: from msvcrt import getch key= ord(getch()) #getting the ASCII character for a key that was pressed def(key): #converting the key to virtual key code for example: the ascii code of a is 41. I want the function to receive it and return 0x41-which is the virtual key code of the key. Thank you in advance for any help! 回答1: Unfortunately you cannot - As you include msvcrt.h, the remaining

问题 I have several large files (3-6 Gb) of 1's and 0's characters in ASCII and I would like to convert it to a simply binary file. Newlines are not important and should be discarded. test.bin below is 568 bytes, I would like the 560 bit file. 0111000110000000101000100000100100011111010010101000001001010000111000 1001100011010100001101110000100010000010000000000001011000010011111100 0100001000010000010000010111011101011111000111111000111001100010100011

问题 Does anyone know of a way to represent Non-ASCII symbols such as this symbol "ŷ" on python in a print statement? 回答1: You should use the UTF-8 coding system. The first line of your Python file should be: # -*- coding: utf-8 -*- If this doesn't work, try wrapping your string with unicode(string). print unicode("éáóý"); If this still doesn't work, try adding these lines before all code but after # - - coding: utf-8 - - import sys if not hasattr(sys, "setdefaultencoding"): reload(sys) sys

问题 I would like to print an ê in Python for windows. When I am at the DOS prompt I can type alt+136 to get an ê, however when I try to do this in python for DOS (code page cp437 or after chcp 1252 to cp1252) I can't type alt+136 to get the ê character. Why is this? print(chr(136)) correctly prints ê under code page cp437, but how can I open a unicode file with these characters: Sokal’, L’vivs’ka Oblast†BucureÅŸti, Romania ง'⌣' and get it to print those characters instead of the below

问题 I have this string: string = '{'id':'other_aud1_aud2','kW':15}' And, simply put, I would like my string to turn into an hex string like this: '7b276964273a276f746865725f617564315f61756432272c276b57273a31357d' Have been trying binascii.hexlify(string) , but it keeps returning: TypeError: a bytes-like object is required, not 'str' Also it's only to make it work with the following method: bytearray.fromhex(data['string_hex']).decode() For the entire code here it is: string_data = "{'id':'"+self

问题 If I cast this on my starting string: echo mb_detect_encoding($string); I get the value: ASCII This string will be downloaded. I suppose it's UTF-8, as that's the default encoding for PHP as well as from the database. Its file extension will be .DAT, and I have already added it to config/mimes.php this way: 'DAT' => 'text/plain; charset=ISO-8859-1' Then if I try to download that string, using the download helper of Codeigniter (assume I have already loaded the helper) force_download('MYFILE

问题 i have file having name "SSE-Künden, SSE-Händler.pdf" which having those two unicode char ( ü,ä) when i am printing this file name on python interpreter the unicode values are getting converted into respective ascii value i guess 'SSE-K\x81nden, SSE-H\x84ndler.pdf' but i want to test dir contains the pdf file of name 'SSE-Künden, SSE-Händler.pdf' i tried this: path = 'C:\test' for a,b,c in os.walk(path): print c ['SSE-K\x81nden, SSE-H\x84ndler.pdf'] how do i convert this ascii chars to its
