1、FizzBuzz：编写一个程序打印1-100的数字。碰到3的倍数时，打印"Fizz"，碰到5的倍数时，打印“Buzz”. 如果是3和5的倍数，打印"FizzBuzz",其余则打印数字。

class FizzBuzz:
    def __init__(self):
        
    
        for i in range(1,101):
            if i%3==0:
                print("Fizz")
            elif i%5 ==0:
                print("Buzz")
            elif i%3==0 and i%5==0:
                print("FizzBuzz")
            else:
                print(i)

    

    
FizzBuzz = FizzBuzz()
FizzBuzz

2、顺序搜索

class SearchAlgorithm:
    def Sequential_search(self,num_list,n):
        
      
        for i in num_list:
            if i == n:
                return True
                break
        else:
            return False

num_list = range(0,100)
s1 = SearchAlgorithm()
print(s1.Sequential_search(num_list,200))

3、回文词。

class Palindrome:
    def word(self,word):
        word = word.lower()
        if word[::-1]==word:
            return True
        else:
            return False

word = Palindrome()
print(word.word("mom"))

4、变位词

class Anagram:
    def word(self,word1,word2):
        word1 = word1.lower()
        word2 = word2.lower()
        if sorted(word1)==sorted(word2):
            return True
        else:
            return False


word = Anagram()
print(word.word("iceman", "cinema"))
