四、编程题请编写一个Python程序,实现将十进制数转换为二进制数的功能。```pythondef decimal_to_binary(decimal):binary =

EBCDIC(Extended Binary Coded Decimal Interchange Code)是IBM于1963年至1964年间推出的字符编码表。它是根据早期打孔机式的二进制编码的十进制数(BCD,Binary Coded Decimal)排列而成的。在EBCDIC编码表中,特定的字节值被分配给不同的字符和控制功能。例如,在编码表中,0x00 - 0x3F及0xFF为控制字符,0x40为空格,0x...

比特操作注意一: 适用范围 Note that you can only do bitwise operations on an integer. Trying to do them on strings or floats will result in nonsensical output!
