(Depending on your system, you may see the actual capital-delta glyph instead of a \\u escape.)\n\n>>> \"\\N{GREEK CAPITAL LETTER DELTA}\" # Using the character name '\\u0394' >>> \"\\u0394\" # Using a 16-bit hex value '\\u0394' >>> \"\\U00000394\" # Using a 32-bit hex value '\\u0394'\n\nIn addition, one can create a string using the ~bytes.decode method of bytes. This method takes an encoding argument, such as UTF-8, and optionally an errors argument.\n\nThe errors argument specifies the response when the input string can't be converted according to the encoding's rules. Legal values for this argument are 'strict' (raise a UnicodeDecodeError exception), 'replace' (use U+FFFD, REPLACEMENT CHARACTER), 'ignore' (just leave the character out of the Unicode result), or 'backslashreplace' (inserts a \\xNN escape sequence). The following examples show the differences\n\nEncodings are specified as strings containing the encoding's name. Python comes with roughly 100 different encodings; see the Python Library Reference at standard-encodings for a list. Some encodings have multiple names; for example, 'latin-1', 'iso_8859_1' and '8859' are all synonyms for the same encoding.\n\nOne-character Unicode strings can also be created with the chr built-in function, which takes integers and returns a Unicode string of length 1 that contains the corresponding code point. The reverse operation is the built-in ord function that takes a one-character Unicode string and returns the code point value\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
