Data pre-processing is crucial to ensure that the data is in a suitable format for clustering. It involves steps such as data cleaning, normalization, and dimensionality reduction. Data cleaning eliminates noise, missing values, and irrelevant attributes that may adversely affect the clustering process...
Users can then turn on lazy evaluation using a decorator once they complete the debugging process. Remove ads Conclusion In this tutorial, you learned what lazy evaluation in Python is and how it’s different from eager evaluation. Some expressions aren’t evaluated when the program first ...
The'r'prefix before a string literal in Python denotes a___string, where escape sequences are not processed. The'u'prefix was used in Python 2.x to indicate a___string, representing Unicode characters. In Python 3.x, strings are Unicode by default, so the'u'prefix is ___ wh...
