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.

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.

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
