我们调用get_input_number()获取用户输入。 通过prime_factors()查找并返回质数因子。 最后根据结果输出相应的信息。 类图 为了便于理解本代码的结构,以下是相应的类图: InputHandler+get_input_number()PrimeFactorFinder+is_prime(num)+prime_factors(n)Program+main() 结尾 通过上述步骤,我们成功实现了用 Python ...

# Program to check if a number is prime or not num = 29 # To take input from the user #num = int(input("Enter a number: ")) # define a flag variable flag = False if num == 0 or num == 1: print(num, "is not a prime number") elif num > 1: # check for factors for...
put the factor and its count into a tuple and make a list # of these tuples so we can sort them: factorsByCount = [] for factor in factorCounts: # Exclude factors larger than MAX_KEY_LENGTH:
Python | sympy.primefactors()方法 原文:https://www . geesforgeks . org/python-sympy-prime factors-method/ 借助 sympy.primefactors() 方法,可以求出给定数的素数因子。与factory int()不同, primefactors() 不返回 -1 或 0 。 语法:素因子(n) 开发文档
Python sympy.primefactors()用法及代码示例 借助于sympy.primefactors()方法,我们可以找到给定数的素数。与factorint()不同,primefactors()不返回-1或0。 用法:primefactors(n) 参数: n –它表示一个整数。 返回值:返回给定整数的素数的列表。 示例1:...
Prime factorization refers to finding all the prime numbers that multiply to make up the original number. We can consider a simple example of the number 6. The prime factorization of this number yields two factors, 2 and 3. Different Approaches to Find Prime Factors in Python ...
