To use slicing for removing the first element of the list, we will take out the sub list starting from the second element and we will leave behind the first element. Thus the first element will be removed from the list. This can be done as follows. ...
zip can take an arbitrary number of sequences, and the number of elements it produces is determined by theshortestsequence. Copy seq3 = [False,True]# print(list(zip(seq1, seq2, seq3)))# [('foo', 'one', False), ('bar', 'two', True)] ...
first element is a list of a word in the words list (where the elements are the individual characters (or subwords in later iterations) of the word), and the second element is an integer representing the frequency of the word in the ...
