python chr()、unichr()和ord()

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> chr()、unichr()和ord() chr()函数用一个范围在range(256)内的(就是0~255)整数作参数,返回一个对应的字符。unichr()跟它一样,只不过返回的是Unicode字符,这个从Python 2.0才加入的unichr()的参数范围依赖于你的Python是如何被编译的。如果是配置为USC2的Unicode,那么它的允许范围就是range(65536)或0x0000-0xFFFF;如果配置为UCS4,那么这个值应该是range(1114112)或0x000000-0x110000。如果提供的参数不在允许的范围内,则会报一个ValueError的异常。 ord()函数是chr()函数(对于8位的ASCII字符串)或unichr()函数(对于Unicode对象)的配对函数,它以一个字符(长度为1的字符串)作为参数,返回对应的ASCII数值,或者Unicode数值,如果所给的Unicode字符超出了你的Python定义范围,则会引发一个TypeError的异常。 >>> chr(65) 'A' >>> ord('a') 97 >>> unichr(12345) u'\u3039' >>> chr(12345) Traceback (most recent call last): File

asc and chr equivalent in C/C++

江枫思渺然 提交于 2019-12-20 01:58:06
问题 Well the title pretty much sums it up. I want to use something like asc("0") in C++, and want to make the program platform independent so don't want to use 48! Any help appreciated. 回答1: You can simply use single-quotes to make a character constant: char c = 'a'; The character type is a numeric type, so there is no real need for asc and chr equivalents. Here's a small example that prints out the character values of a string: #include <stdio.h> int main(int argc, char **argv) { char str[] =

ORD and CHR a file in Bash

拟墨画扇 提交于 2019-12-13 10:59:47
问题 I build ord and chr functions and they work just fine. But if I take a file that contains \n , for example: hello CHECK THIS HIT YES when I ord everything I don't get any new line values. Why is that? I'm writing in Bash. Here is the code that I am using: function ord { ordr="`printf "%d\n" \'$1`" } TEXT="`cat $1`" for (( i=0; i<${#TEXT}; i++ )) do ord "${TEXT:$i:1}" echo "$ordr" done 回答1: Your ord function is really weird. Maybe it would be better to write it as: function ord { printf -v
