Python Unicode data:

The 'unicodedata' library in python is helpful in defining the
properties for all the Unicode characters available in the Unicode
database. This library accesses the Unicode Character Database (UCD) for
defining the characters.

The next three functions defined here are:

1. unicodedata.category(chr)

2. unicodedata.bidirectional(chr)

3. unicodedata.combining(chr)

Unicodedata.category(chr):

This is a function in the unicodedata library for python which returns
the category assigned to the unicode character ‘chr’.

Each unicode character is assigned a category. All such categories are
listed here:

[Cc]    -         Other,Control

[Cf]    -         Other,Format

[Cn]    -         Other,Not Assigned(no characters in the file has this property)

[Co]    -         Other,Private Use

[Cs]    -         Other,Surrogate

[LC]    -         Letter,Cased

[Ll]               -         Letter,Lowercase

[Lm]   -         Letter,Modifier

[Lo]    -         Letter,Other

[Lt]    -         Letter,Title case

[Lu]    -         Letter,Uppercase

[Mc]   -         Mark,Spacing Combining

[Me]   -         Mark,Enclosing

[Mn]   -         Mark,Non-spacing

[Nd]   -         Number,Decimal Digit

[Nl]    -         Number,Letter

[No]   -         Number,Other

[Pc]    -         Punctuation,Connector

[Pd]    -         Punctuation,Dash

[Pe]    -         Punctuation,Close

[Pf]    -         Punctuation,Final quote (may behave like ps or Pe depending on usage)

[Pi]     -         Punctuation,Initial quote (may behave like Ps or Pe depending on usage)

[Po]    -         Punctuation,Other

[Ps]    -         Punctuation,Open

[Sc]   -         Symbol,Currency

[Sk]   -         Symbol,Modifier

[Sm]  -         Symbol,Math

[So]   -         Symbol,Other

[Zl]    -         Seperator,Line

[Zp]   -         Seperator,Paragraph

[Zs]   -         Seperator,Space

Thus this function returns these categories.

Unicodedata.bidirectional(chr):

This is a function in the unicodedata library in python and it returns the Bidirectional class assigned to the character ‘chr’ passed to the argument as a string.
