Hey, I'm doing a project which includes data mining but for that I want to build a crawler which extract pubmed articles ids using a single term like cancer or tumor? (semantics based ) I'm currently working in python. If someone is familiar with this issue kindly help me

Use Biopython.
An example, cancer as a search term.
from Bio import Entrez
Entrez.email = "yourmail@gmail.com"
handle = Entrez.esearch(db="pubmed", term="cancer", retmax="10", sort="relevance", retmode="xml")
records = Entrez.read(handle)
print(records["IdList"])
I would like to suggest that you write Python3 in your examples (using print as a function) to make this code snippet valid on all python versions. Python2 will only be around for limited time, so better bite the bullet now and get used to Python3 syntax.
thanks for the suggestion.
What if I want urls of a specific word instead of ids?
Sorry, what do you mean by "urls of specific word"? If you are talking about article URLs, use https://www.ncbi.nlm.nih.gov/pubmed/ as base URL and add the fetched PMIDs after it.
Hlo sir. I want to extract specific gene articles. for every gene I have number of articles so how can I extract pubmed id and abstract of the article alone. could you please suggest how to extract id and abstract of the article alone. thanking you sir
You can also try out Annotations API from Europe PMC. It allows you to retrieve a list of PMIDs for artciles that contain text-mined terms. Diseases (including cancer or tumor) is one of the annotation types. So for retrieving article iDs for cancer you could use the following response URL: https://www.ebi.ac.uk/europepmc/annotations_api/annotationsByEntity?entity=cancer&filter=1&format=ID_LIST&pageSize=4
how can I download all the abstracts belongs to the cancer articles sir.
