LPSN-API - Programmatic Access to LPSN
Project description
LPSN API
Using the LPSN API requires registration. Registrations is free but the usage of LPSN data is only permitted when in compliance with the LPSN copyright. See LPSN copyright notice for details.
Please register here.
The Python package can be initialized using your login credentials:
import lpsn
client = lpsn.LpsnClient('name@mail.example', 'password')
# the prepare method fetches all LPSN-IDs matching your query
# and returns the number of IDs found
count = client.search(taxon_name='Sulfolobus', correct_name='yes')
print(count, 'entries found.')
# the retrieve method lets you iterate over all results
# and returns the full entry as dict
# Entries can be further filtered using a list of keys (e.g. ['keywords'])
for entry in client.retrieve():
print(entry)
Example queries:
You can use IDs to query LPSN as described here. Note that when using the parameter id
, all other parameters are ignored.
# Search by LPSN-IDs (either semicolon separated or as list):
query = {"id": 520424}
query = {"id": "520424;4948;17724"}
query = {"id": [520424, 4948, 17724]}
# run query
client.search(**query)
Or you can use all the advanced search parameters that are described here.
Note that dashes (-
) are replaced by underscores when used as python parameters.
# Example looking for validly published species from Escherichia that have risk group 1:
client.search(taxon_name='Escherichia', category='species', riskgroup='1', validly_published='yes')
# The same example using a Python dictionary:
query = {
'taxon-name': 'Escherichia',
'category': 'species',
'riskgroup': '1',
'validly-published': 'yes'
}
client.search(**query)
Filtering
Results from the retrieve
Method of both clients can be further filtered. The result contains a list of matched keyword dicts:
result = client.retrieve(filter=["full_name", "lpsn_taxonomic_status"])
print({k:v for x in result for k,v in x.items()})
The printed result will look like this:
{782310: [{'full_name': 'Sulfolobus acidocaldarius'},
{'lpsn_taxonomic_status': 'correct name'}],
782311: [{'full_name': 'Sulfolobus brierleyi'},
{'lpsn_taxonomic_status': 'synonym'}],
782312: [{'full_name': 'Sulfolobus hakonensis'},
{'lpsn_taxonomic_status': 'synonym'}],
782313: [{'full_name': 'Sulfolobus metallicus'},
{'lpsn_taxonomic_status': 'synonym'}],
