#提供一个大循环数字序列给numFor NUM in range (2,100):#循环条件是: Iterates through a sequence of numbers from 2 to NUM, each time the number sequence of loops is assigned to I.For I in Range (2,num):#如果num余运算i为0, break the small loop over to the big loop.If num%i = = 0:BreakThe number (prime) is printed #小循环余运算到了num的尽头for不再成立 (the loop is not interrupted).ElsePrint (num)#我可能一开始就啃

Topic Content: Find the nth number of Moenissen. P is prime and M is prime, and satisfies the equation m=2**p-1, then the M is called Moenissen number. For example, p=5,m=2**p-1=31,5 and 31 are primes, so 31 is a Moenissen

Topic Description: The number that contains only the factors 2, 3, and 5 is called the Ugly (Ugly number). For example, 6, 8 are ugly numbers, but 14 is not because it contains factor 7. We used to think of 1 as the first ugly number. Find the nth
