我想打印1-100的数字，并跳过被3和5整除的数字，而当我使用代码1时，我没有得到正确的输出，我会完全计数1-100
#CODE1
i=1
a=1
while i<=100:
if (a%3==0 and a%5==0) :
a=a+1
else:
print(a)
a=a+1
i=i+1
但是当我使用CODE-2时，我得到了预期的结果
#CODE2
i=1
a=1
while i<=100:
if ((a%3 and a%5)==0) :
a=a+1
else:
print(a)
a=a+1
i=i+1
注意代码的第四行，为什么第一代码有误？
答案 0 :(得分：1)
考虑一下：
a = 10
(a%3 == 0) and (a%5 == 0) # False
(a%3 and a%5) == 0 # True
第一次尝试错误地给了False，因为它需要同时满足两个条件。您需要使用or。如果您仔细查看，则会排除某些数字（例如15），这与同时包含3和5的数字相符。
第二次尝试是正确的，因为如果a不能被 3或5整除，则表达式的计算结果为False，而0 == False给出{{ 1}}。更惯用的是写：
True答案 1 :(得分：1)
第一个程序不正确，因为您在6-7行中增加了计数器，而没有检查是否需要打印该数字。
更简洁的写法可能是：
for counter in xrange(1, 101):
if not ((counter % 5 == 0) or (counter % 3 == 0)):
print (a)
答案 2 :(得分：1)
问题是在CODE＃1的第5行中将“和”更改为逻辑“或”。当前版本1仅在同时满足两个条件时才跳过数字。当满足一个或两个条件时，您想跳过数字。
PS：我想提出一种更快更有效的方法来获得此结果。

答案是：
import numpy as np
numbers = np.arange(1,101,1)
print('Original numbers \n', numbers)
print('Required numbers \n', numbers[(numbers%3!=0) & (numbers%5!=0)])
答案 3 :(得分：1)
检查这也有效！ 100%
def result(N):
for num in range(N):
if num % 3 == 0 and num % 5 == 0:
print(str(num) + " ", end="")
else:
pass
if __name__ == "__main__":
N = 100
result(N)

False
else:

n=n+1
答案 6 :(得分：0)
在第一个代码中，您使用的和几乎与您所需要的相反，即或语句。我建议您将和换成或语句。
#CODE
i=1
a=1
while i<=100:
if (a%3==0 or a%5==0) :
a=a+1
else:
print(a)
a=a+1
i=i+1
在第二个代码中，您使用的 nand 在这种情况下与 or 非常相似，因此适用于数据集的第一部分。但是，在更复杂的代码中，这会使您对某些检查产生误判，因此，如果没有严格的要求，我应该避免这样做。
答案 7 :(得分：0)
我从你的问题中得到了这个输出。
for i in range(1, 100):
if(i%3==0 or i%5==0):
continue
print(i)
答案 8 :(得分：0)
这样做。
for i in range(1, 101):

print(i)
答案 9 :(得分：0)
for i in range(1, 101):
if i%3==0 and i%5==0:

答案 10 :(得分：0)
试试这个：

i=1
while(i<=100):
