What is the opposite of python's ord() function?

The opposite of Python's ord() function, which returns the Unicode code point of a character, is the chr() function. The chr() function takes an integer representing a Unicode code point and returns the corresponding character.

Here's an example to illustrate the use of both ord() and chr() functions:

# Using ord() to get the Unicode code point of a character character = 'A' unicode_code_point = ord(character) print(f"Unicode code point of '{character}' is {unicode_code_point}") # Using chr() to get the character from a Unicode code point unicode_code_point = 65 # ASCII code for 'A' character = chr(unicode_code_point) print(f"Character corresponding to Unicode code point {unicode_code_point} is '{character}'")

Output:

Unicode code point of 'A' is 65 Character corresponding to Unicode code point 65 is 'A'

So, while ord() converts a character to its Unicode code point, chr() converts a Unicode code point back to its corresponding character.

Examples

  1. What Does the chr() Function Do in Python?

    • Description: chr() is the opposite of ord(). It returns the character corresponding to a given Unicode code point.
    • Code:
      code_point = 97 character = chr(code_point) print(character) # Output: 'a'

  2. Using chr() to Convert Integers to Characters

    • Description: Convert an integer representing a Unicode code point to its corresponding character using chr().
    • Code:
      code_point = 65 character = chr(code_point) print(character) # Output: 'A'

  3. How to Convert ASCII Values to Characters in Python

    • Description: ASCII values can be converted to characters with chr(), where ASCII values range from 0 to 127.
    • Code:
      ascii_value = 48 character = chr(ascii_value) print(character) # Output: '0'

  4. Converting Unicode Code Points to Characters with chr()

    • Description: chr() can convert a Unicode code point to its corresponding character, supporting a wide range of characters beyond ASCII.
    • Code:
      unicode_point = 8364 # Euro sign character = chr(unicode_point) print(character) # Output: '�'

  5. Converting Characters to Unicode Code Points and Back

    • Description: Use ord() to convert a character to its Unicode code point and chr() to convert back.
    • Code:
      char = 'b' code_point = ord(char) print(code_point) # Output: 98 recovered_char = chr(code_point) print(recovered_char) # Output: 'b'

  6. Looping Through Unicode Code Points and Converting with chr()

    • Description: Iterate over a range of Unicode code points and use chr() to convert them to characters.
    • Code:
      for code_point in range(65, 70): print(chr(code_point)) # Outputs: 'A', 'B', 'C', 'D', 'E'

  7. Creating a String from a List of Unicode Code Points with chr()

    • Description: Convert a list of Unicode code points to a string by using chr() for each code point.
    • Code:
      code_points = [72, 101, 108, 108, 111] result_string = ''.join(chr(cp) for cp in code_points) print(result_string) # Output: 'Hello'

  8. Using chr() to Create Special Characters

    • Description: Generate special characters like newline (\n), tab (\t), or other control characters using chr().
    • Code:
      newline_char = chr(10) # Newline tab_char = chr(9) # Tab formatted_string = f"First line{newline_char}Second line{tab_char}Indented" print(formatted_string) # Output: # First line # Second line Indented

  9. How to Convert Binary to Characters Using chr()

    • Description: Convert binary numbers to characters by first converting them to integers and then using chr().
    • Code:
      binary = '01100001' # Binary for 'a' code_point = int(binary, 2) character = chr(code_point) print(character) # Output: 'a'

  10. Using chr() to Convert Hexadecimal to Characters

    • Description: Convert hexadecimal values to characters by first converting them to integers and then using chr().
    • Code:
      hex_value = '41' # Hexadecimal for 'A' code_point = int(hex_value, 16) character = chr(code_point) print(character) # Output: 'A'
