Learn SPACY with Real Code Examples
Updated Nov 24, 2025
Practical Examples
Load a model: nlp = spacy.load('en_core_web_sm')
Tokenize text: doc = nlp('Hello world!')
Extract named entities: [(ent.text, ent.label_) for ent in doc.ents]
Part-of-speech tagging: [(token.text, token.pos_) for token in doc]
Custom rule matching using Matcher or PhraseMatcher
Troubleshooting
Ensure correct model is downloaded and loaded
Check language model compatibility with spaCy version
