运行此代码时,我一直有错误。我想知道出了什么问题。代码必须能够读取单词和整数并重复提示(请输入一个整数> = 2:'),直到它大于或等于2.提前感谢。
def prime_number():
prime_num = input('Please enter an integer >= 2: ')
while not(prime_num.isdigit() and int(prime_num)<1):
prime_num = input('Please enter an integer >= 2: ')
for i in range(2,int(prime_num)+1):
for x in range(2,i):
if i%x == 0:
break
else:
print (i)
答案 0 :(得分:0)
while
条件是错误的这应该有效:
def prime_number():
prime_num = input('Please enter an integer >= 2: ')
while not (prime_num.isdigit() and not int(prime_num)<1):
prime_num = input('Please enter an integer >= 2: ')
for i in range(2,int(prime_num)+1):
for x in range(2,i):
if i%x == 0:
break
else:
print (i)
prime_number()
答案 1 :(得分:0)
您需要输入该功能。这通常在python中完成:
def prime_number():
prime_num = input('Please enter an integer >= 2: ')
while not(prime_num.isdigit() and int(prime_num)<1):
prime_num = input('Please enter an integer >= 2: ')
for i in range(2,int(prime_num)+1):
for x in range(2,i):
if i%x == 0:
break
else:
print (i)
if __name__ == "__main__":
prime_number()
一般的一些建议。我将输入逻辑与素数计算逻辑分开。
