Python 函数 —— ord(), chr()

chr(i)

Return the string representing a character whose Unicode code point is the integer i. For example, chr(97) returns the string ‘a’, while chr(8364) returns the string ‘€’. This is the inverse of ord().

The valid range for the argument is from 0 through 1,114,111 (0x10FFFF in base 16). ValueError will be raised if i is outside that range.

In [4]: chr(14) Out[4]: '\x0e' In [5]: chr(44) Out[5]: ',' In [6]: chr(60) Out[6]: '<'

ord(c)

Given a string representing one Unicode character, return an integer representing the Unicode code point of that character. For example, ord(‘a’) returns the integer 97 and ord(‘€’) (Euro sign) returns 8364. This is the inverse of chr().

In [7]: ord('a') Out[7]: 97 In [8]: chr(97) Out[8]: 'a'
