The simplest way to find and print prime numbers from 1 to N in Python is by using basic iteration and checking for each number’s divisibility. Let me show you an example and the complete code. Example: Here is the complete Python code to print prime numbers from 1 to n in Python. ...
首先第一句话肯定是接受用户输入的数字:n = int(input("please enter the number:")) 接着要计算该数是不是质数,那么就要从2开始一直除到该数之前的那个自然数,很明显是一个数字范围:for i in range(2, n): 在循环体里面,每次循环当然就是要判断当次除法是否是整除,这里可以使用求模运算,也就是取余,当...
【Python】is_prime number 对于一个素数的判定,一般来说是除了一和自身以外不可以被其他数整除。但是换一种方式想,这是两种情况,如果这个数本身就是1,那么不是素数,如果能被2或者以上的数字整除,意味着判断范围可以从2-自身减少到2-自身/2 如下: def is_prime(x): if x <2: return False else: for i ...
In Python, we can also use the for...else statement to do this task without using an additional flag variable. Example 2: Using a for...else statement num = 407 # To take input from the user #num = int(input("Enter a number: ")) if num == 0 or num == 1: print(num, "is...
