class
url_hostname.host.Host(val: str = '', *, second_level_domain: str = '', top_level_domain: str = '', subdomains: Union[Iterable[str], str] = ())¶ Immutable representation of a host in URL Modifying the host will return new instance of the class, thus allowing chaining
Example
>>> leaf 🍃 domain name >>> _|_ __|__ >>> ⸍ ⸌ ⸍ ⸌ >>> www.prixroberval.utc.fr >>> ⸌________________⸍⸌__⸍⸌__⸍ >>> | | | >>> subdomains second top >>> domain domain >>> level level

classmethod
build(second_level_domain: str, top_level_domain: str, subdomains: Iterable[str] = ())¶ Creates and returns a new Host:
- Parameters
second_level_domain (str) – single part
top_level_domain (str) – level in the hierarchical DNS after the root domain
subdomains (Iterable[str], optional) – parts on the left of the domain name
- Returns
new Host instance
- Return type
Examples
>>> Host.build("utc", "fr") Host('utc.fr')
-
property
domain_name¶ Get the minimal part of the domain space that corresponds to an IP address as a string
- Returns
second and top level domains
- Return type
Examples
>>> host = Host.build("utc", "fr", subdomains=("www", "prixroberval")) >>> host.domain_name Host('utc.fr')
-
is_relative_to(*other)¶ Whether or not this Host is relative to other
- Returns
whether this Host is relative to other
- Return type
bool
Examples
>>> docs = Host.build('amazon', 'com', ("docs",'aws')) >>> macie = docs.with_subdomains(("us-west-2", "redirection", "macie", "aws")) >>> macie.is_relative_to(docs) True
-
property
leaf¶ Left most part of the domain
- Returns
host domain’s leaf
- Return type
str
Examples
>>> host = Host.build("utc", "fr", subdomains=("www", "prixroberval")) >>> host.leaf 'www'
-
relative_to(*other)¶ Compute new a version of this Host relative to the path represented by other
- Returns
new with common domain names
- Return type
- Raises
ValueError – when no relative host exists
Examples
>>> docs = Host.build('amazon', 'com', ("docs",'aws')) >>> macie = docs.with_subdomains(("us-west-2", "redirection", "macie", "aws")) >>> macie.relative_to(docs) Host('aws.amazon.com')
-
with_leaf(leaf: str)¶ New Host with the left most part of the domain replaced
- Returns
new with leaf replaced
- Return type
Examples
>>> host = Host.build("wikipedia", "org", subdomains="en") >>> host.with_leaf('fr') Host('fr.wikipedia.org')
-
with_subdomains(subdomains: Union[Iterable[str], str])¶ New Host with subdomains replaced
- Parameters
subdomains (Union[Iterable[str], str]) – subdomains with leaf at left
- Returns
new with subdomains replaced
- Return type
Examples
>>> host = Host.build("utc", "fr", subdomains=("www", "prixroberval")) >>> host.with_leaf('prixroberval') Host('prixroberval.utc.fr')
