Label encoder vs One Hot Encoder

 

One-Hot Encoding vs. Label Encoding using Scikit-Learn

when to use label encoder?

If your column has two variables for example yes and no at this situation this method works perfectly well 

code:

here dataset is our excel or csv file 

What is label encoder how it differ from one-hot encoder?
