Question

Number 4 please and thank you

Complete the Function (4) The isslice function returns True if its first argument is a subsequence o s hrst argument is a subsequence of its second argument, for any sequence type. So, for example: >>> isslice('bam', "bimb amboo") True >>> isslice ([21,22), list (range (10))) False >>> isslice ([0,0,0).[0,0,0]) True Unfortunately, the definition is incomplete. Fill in the blanks to complete the definition. def isslice(x, S): return -----([x==s [ _____) for i in range(_____) 1) (5) Given a sequence, S, and an integer i <= len(S), return a tuple that consists of the i "middle" elements of S. >>> extractMiddle([1, 2, 3, 4, 5], 1) (3.) >>> extractMiddle([1, 2, 3, 4, 5), 3) (2, 3, 4) >>> extractMiddle([1, 2, 3, 4, 5, 6], 3) (2, 3, 4) >>> extractMiddle('The University of Iowa', 5) ('e', 'r', 's', 'i', 't') >>> extractMiddle(range (10), 3) (3, 4, 5) def extractMiddle(S, i): return(_

def isslice(x,s):
return( len(s)>=len(x) and max([x==s[i:i+len(x)] for i in range(len(s)-len(x)+1)]))

In [68] def isslice (x,s) return len(s)>=len (x) and max ( [X==s [1 : 1+len (x)] for i in range (len(s)-len (x)+1) ] ) ) In [67] isslice('bam, 'bimbamboo) out[67] True In [66] isslice('bam', 'b') Out[66] False isslice ( [ 21, 22], list (range (10)) ) [65] In out[65] False isslice ( [0, 0, 0] , [e,e0, 0] ) [64] In out[64] True
