This argument is optional. Below is an implementation of the zip function and itertools.izip which iterates over 3 lists: During training, randomly zeroes some of the elements of the input tensor with probability p using samples from a Bernoulli distribution. Vergessen Sie jedoch nicht, dass der eingentliche Enumerate-Grundbefehl "enumerate()" lautet. Start Learning Python. It is recommended to play around more, get creative and explore the potential of lists further. Check leap year. You may want to look into itertools.zip_longest if you need different behavior.
