itertools chain串联 可以将两个字符串放在一起迭代from itertools import chaindata1 = "123"data2 = "456"for x in chain(data1,data2): print(x)

def Num(num): value = []# 2为最小的质数，从2开始做穷举，直到这个数本身 for i in range(2, num + 1):# 从2到获取到的数求余，余数为0则不是质数，跳出循环 for j in range(2, i): if i % j == 0: break ...

# 求一个数里面所有的质数def Num(num): value_list = [] for i in range(2, num + 1): for j in range(2, i): if i % j == 0: break else: # 求余不为0则为质数 ...
