Unicodedata — Python Unicode database

Functions defined by the module:

  • unicodedata.lookup (name)
    This function looks for a character by name. If a symbol with the given name is found in the database, then the corresponding symbol is returned, otherwise a Keyerror is thrown.

    Example:

    import unicodedata

     

    print unicodedata.lookup ( `LEFT CURLY BRACKET` )

    print unicodedata.lookup ( ` RIGHT CURLY BRACKET` )

    print unicodedata .lookup ( `ASTERISK` )

      
    # gives error as is
    # no symbol named ASTRA
    # print unicodedata.lookup (& # 39; ASTER & # 39;)

    Output:

     {} * 
  • unicodedata.name (chr [, default])
    This function returns the name assigned to the given character as a string. If no name is specified, the function returns a default value, otherwise a ValueError is thrown if no name is specified.

    Example:

    import unicodedata

      

    print unicodedata.name (u `/` )

    print unicodedata.name (u `|` )

    print unicodedata. name (u `:` )

    Output:

     SOLIDUS VERTICAL LINE COLON 
  • unicodedata.decimal (chr [, by default])
    This function returns the decimal value assigned to the given character as an integer. If no value is specified, the function returns the default value, otherwise ValueError is raised if no value is specified.

    Example:

    import unicodedata

      

    print unicodedata.decimal (u `9` )

    print unicodedata.decimal (u `a` )

    Output:

     9 Traceback (most recent call last): File "7e736755dd176cd0169eeea6f5d32057.py", line 4, in print unicodedata.decimal (u`a`) ValueError: not a decimal 
  • unicodedata.digit (chr [, default])
    This function returns the numeric value assigned to the given character as an integer. If no value is specified, the function returns the default value, otherwise ValueError is raised if no value is specified.

    Example:

    import unicodedata

     

    print unicodedata.decimal (u `9` )

    print unicodedata.decimal (u `143` )

    Output:

     9 Traceback (most recent call last): File "ad47ae996380a777426cc1431ec4a8cd.py", line 4, in print unicodedata. decimal (u`143`) TypeError: need a single Unicode character as parameter 
  • un icodedata.numeric (chr [, default])
    This function returns the numeric value assigned to the given character as an integer. If no value is specified, the function returns the default value, otherwise ValueError is raised if no value is specified.

    Example:

    import unicodedata

      

    print unicodedata.decimal (u `9` )

    print unicodedata.decimal (u `143` )

    Output:

     9 Traceback (most recent call last): File "ad47ae996380a777426cc1431ec4a8cd.py", line 4, in print unicodedata.decimal (u`143`) TypeError: need a single Unicode character as parameter 
  • unicodeda ta.category (CHR)
    This function returns the general category assigned to the given character as a string. For example, it returns L for a letter and U for uppercase letters.

    Example:

    import unicodedata

     

    print unicodedata.category (u `A` )

    print unicodedata.category (u `b` )

    Output:

     Lu Ll 
  • unicodedata.bidirectional (CHR)
    This function returns a bi-directional class assigned to the given character as a string. For example, it returns “A” for Arabic and “N” for number. This function returns an empty string if no such value is defined.

    Example:

    import unicodedata

     

    print unicodedata.bidirectional (u `u0660` )

    Output:

     AN 
  • unicodedata.normalize (form, uniform)
    This function returns the normal form form for a Unicr Unicode string. Valid values ​​for the form are NFC, NFKC, NFD, and NFKD.

    Example:

    from unicodedata import normalize

     

    print `% r` % normalize ( `NFD` , u `u00C7` )

    print `% r` % normalize ( `NFC` , u ` Cu0327` )

    print  `% r` % normalize ( ` NFKD` , u `u2460` )

    Output:

     u`Cu0327` u`xc7` u`1`
