+## Sentiment Analysis of Spanish-English  Code-Mixed Data
+
+* **Method-1**
+
+```py
+
+from transformers import AutoTokenizer, AutoModelForSequenceClassification, pipeline
+
+tokenizer = AutoTokenizer.from_pretrained("sagorsarker/codeswitch-spaeng-sentiment-analysis-lince")
+
+model = AutoModelForSequenceClassification.from_pretrained("sagorsarker/codeswitch-spaeng-sentiment-analysis-lince")
+
+nlp = pipeline('sentiment-analysis', model=model, tokenizer=tokenizer)
+sentence = "El perro le ladraba a La Gatita .. .. lol #teamlagatita en las playas de Key Biscayne este Memorial day"
+nlp(sentence)
+
+```
+
+* **Method-2**
+
+```py
+from codeswitch.codeswitch import SentimentAnalysis
+sa = SentimentAnalysis('spa-eng')
+sentence = "El perro le ladraba a La Gatita .. .. lol #teamlagatita en las playas de Key Biscayne este Memorial day"
+result = sa.analyze(sentence)
+print(result)
+```
