array模块支持相当数量的数据类型，包括整数、浮点数和字节值。以下是常用的可创建类型的typecode代码。‘b’：有符号的字节（对应C语言的signed char）‘B’：无符号的字节（对应C语言的unsigned char）‘u’：Unicode字符串（对应C语言的PY_UNICODE）‘h’：有符号的短整数（对应C语言的short）‘H’：无符号的短...

1)整数类型 说明: 对于整数类型,MySQL还支持在类型名称后面加小括号(M),而小括号中的M表示显示宽度,M的取值范围是(0, 255)。int(M)这个M在字段的属性中指定了unsigned(无符号)和zerofill(零填充)的情况下才有意义。表示当整数值不够M位时,用0填充。如果整数值超过M位但是没有超过当前数据类型的范围时,就...

QuestionFriday, April 9, 2010 1:19 PMHi,I have a situation where I need to write a function for converting unsigned char array to the char array? Please assume that we have Japanese and Chinese character present in unsigned array. Also assume that they are in UTF-8 format....
