ASCII ((American Standard Code for Information Interchange): 美国信息交换标准代码）是基于拉丁字母的一套电脑编码系统，主要用于显示现代英语和其他西欧语言。它是最通用的信息交换标准，并等同于国际标准ISO/IEC 646。
在python中，经常要用到它和字符的相互转换，这里做了一个例子，仅供参考：
1
c = input(
"
Please input a char:
"
)
2
a = int(input(
"
Please input a ascii:
"
))
3
while
True:
4
if
a <
0:
5
print
(
"
ascii is wrong, Plese try again
"
)
6
a = int(input(
"
Please input a ascii:
"
))
7
elif
a > 1000
:
8
print
(
"
ascii is wrong, Plese try again
"
)
9
a = int(input(
"
Please input a ascii:
"
))
10
else
:
11
break
12
13
print
(
"
this is a ascii test
"
)
14
print
(
"
assic is:
"
,ord(c))
15
print
(
"
char is:
"
, chr(a))
