英文文档:
chr
(i)chr(97)
returns the string ‘a‘
, while chr(8364)
returns the string ‘€‘
. This is the inverse of ord()
.ValueError
will be raised if i is outside that range>>> chr(97) #参数类型为整数 ‘a‘ >>> chr(‘97‘) #参数传入字符串时报错 Traceback (most recent call last): File "<pyshell#6>", line 1, in <module> chr(‘97‘) TypeError: an integer is required (got type str) >>> type(chr(97)) #返回类型为字符串 <class ‘str‘>
2. 它的功能与ord函数刚好相反
>>> chr(97) ‘a‘ >>> ord(‘a‘) 97
3. 传入的参数值范围必须在0-1114111(十六进制为0x10FFFF)之间,否则将报ValueError错误
>>> chr(-1) #小于0报错 Traceback (most recent call last): File "<pyshell#10>", line 1, in <module> chr(-1) ValueError: chr() arg not in range(0x110000) >>> chr(1114111) ‘\U0010ffff‘ >>> chr(1114112) #超过1114111报错 Traceback (most recent call last): File "<pyshell#13>", line 1, in <module> chr(1114112) ValueError: chr() arg not in range(0x110000)
