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 (0x10...
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 integer97andord('€')(Euro sign) returns8364. This is the inverse ofchr(). ...
Return the string representing a character whose Unicode code point is the integer i. For example, chr(97) returns the string 'a'. 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...
The chr function returns a string representing a character whose Unicode code point is the integer passed to it. It's the inverse of ord. Key characteristics: accepts integers from 0 to 1,114,111 (0x10FFFF in base 16). Raises ValueError for out-of-range values. Returns a single-...
For example,chr(97)returns the string'a', whilechr(8364)returns the string'€'. This is the inverse oford(). The valid range for the argument is from 0 through 1,114,111 (0x10FFFF in base 16).ValueErrorwill be raised ifiis outside that range...
Note: The inverse is not necessarily true: Objects with equal hash values may themselves be unequal. (This causes what's known as a hash collision, and degrades the constant-time performance that hashing usually provides.)▶ Deep down, we're all the same.class WTF: passOutput...
If the new position of the letter doesn’t go beyond the position of the last letter (alphabet[-1]), then you return the letter at this new position. To do that, you use the built-in function chr(). chr() is the inverse of ord(). It takes an integer representing the Unicode cod...
