ord () and chr ()
- the ord () function is CHR () function (for 8-bit ASCII string) pairing function, which takes a string (Unicode character) as a parameter and returns the value corresponding to ASCII or Unicode value
- CHR () returns an integer value corresponding to the current ASCII characters
>>> ord('a') 97 >>> ord('z') 122 >>> ord('A') 65 >>> ord('Z') 90 >>> chr(65) 'A' >>> chr(90) 'Z' >>> chr(97) 'a' >>> chr(122) 'z'
# Letter az calculate a sum of ASCII code
>>> result = 0 >>> for i in range(ord('a'),ord('z')+1): ... result +=i ... >>> print(result) 2847
