len(str1.encode()),len(str.encode(‘gbk’))将字符串进行编码后再获取它的字节数 在Python 中,不同的字符所占的字节数不同,数字、英文字母、小数点、下划线以及空格,各占一个字节,而一个汉字可能占 2~4 个字节,具体占多少个,取决于采用的编码方式。例如,汉字在 GBK/GB2312 编码中占用 2 个字节,而在...
在上例test.c中,首先是利用daemon创建一个后台进程,在daemon后面的函数将是在后台执行的代码,特别是对于服务器代码而言,是一个while(1)总是监听端口的死循环,因此在关闭后台进程的时候,需要知道后台进程的pid,所以程序中在daemon执行后,利用getpid()函数获得子进程的pid,并将pid保存在一个文件中。 对于脚本程序,由...
