Two arrays are called similar if one can be obtained from another by swapping at most one pair of elements in one of the arrays. Given two arrays a and b, check whether they are similar. def areSimilar(a, b): return sorted(a)==sorted(b) and sum([c!=d for c,d in zip(a,b)])

Given a rectangular matrix of characters, add a border of asterisks(*) to it. def addBorder(picture): a = len(picture[0]) + 2 return ["*" * a] + ["*" + i + "*" for i in picture] + ["*" * a] "*"+i+"*"말고 i.center()쓰는것도 좋은 방법이다.
