input: Write a python function to analyze the sentiment of a given text using TextBlob.
  assert analyze_sentiment("I love this!") == {'polarity': 0.5, 'subjectivity': 0.6}
  assert analyze_sentiment("This is terrible.") == {'polarity': -1.0, 'subjectivity': 1.0}
  assert analyze_sentiment("It's okay.") == {'polarity': 0.5, 'subjectivity': 0.6}
output: from textblob import TextBlob
  
  def analyze_sentiment(text):
      blob = TextBlob(text)
      return {'polarity': blob.sentiment.polarity, 'subjectivity': blob.sentiment.subjectivity}
