程序源代码： Question: Determine how many prime numbers are between 101-200 and output all prime numbers. Program analysis: the method to determine prime number: use a number to divide 2 to sqrt (this number). If it can be divided by an integer, it indicates that this number is n...

Determine whether it is a prime number. Then the integer 2 to the number 1/2+1() are sequentially taken to determine the remainder. The reason why the number 1/2+1 is taken here is because the essence of the prime number is to judge the combination of numbers after the factorization ...

The reason this works is a bit subtle and relies on any() and all() using short-circuit evaluation: they only check as many items as necessary to determine the result. Note: If you want to check whether all city names start with the letter "B", then you can look for a ...
