在编程中,ASCII码(American Standard Code for Information Interchange)是一种用于表示字符的标准编码系统。它将每个字符映射到一个唯一的整数值,使得计算机能够处理和表示文本数据。在Python中,我们可以使用ASCII码来执行各种文本操作,比如打印字符、转换字符、比较字符等。 本文将指导刚入行的开发者如何在Python中引入和...
下面是一个完整的示例代码,演示了如何使用Python获取字符的ASCII码和将ASCII码转换为字符: # 获取字符的ASCII码defget_ascii_code(char):ascii_code=ord(char)returnascii_code# 将ASCII码转换为字符defget_character(ascii_code):char=chr(ascii_code)returnchar# 测试代码if__name__=="__main__":char='A'...

ASCII(American Standard Code for Information Interchange)美国信息交换标准代码,它是对字母、数字、符号进行二进制编码的标准。一个ASCII码长度是一个字节,也就是8个bit,最高位是0作为校验位,其余7位使用0和1进行组合(00000000~01111111(0X00~0X7F)),所以ASCII码共有128个。这128个字符包含33个控制字符和95个可...

ASCII Code Chart ASCII was developed from telegraph code. Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. Originally based on the English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart above. The...

ASCII stands for the "American Standard Code for Information Interchange". It was designed in the early 60's, as a standard character set for computers and electronic devices. ASCII is a 7-bit character set containing 128 characters.
