求500以内能被3整除或能被5整除的数的和。(分别用while、do while、for编写程序

while循环:
```python
i = 1
sum = 0
while i <= 500:
if i % 3 == 0 or i % 5 == 0:
sum += i
i += 1
print("500以内能被3整除或能被5整除的数的和为:", sum)
```
do while循环:
```python
i = 1
sum = 0
while True:
if i > 500:
break
if i % 3 == 0 or i % 5 == 0:
sum += i
i += 1
print("500以内能被3整除或能被5整除的数的和为:", sum)
```
for循环:
```python
sum = 0
for i in range(1, 501):
if i % 3 == 0 or i % 5 == 0:
sum += i
print("500以内能被3整除或能被5整除的数的和为:", sum)
```

求500以内能被3整除或能被5整除的数的和用while、do while、for编写程序
在Python中,你可以使用`while`、`do-while`(虽然Python本身并不支持do-while结构,但我们可以模拟类似的功能)或者`for`循环来编写一个求和500以内能被3或5整除的数的程序。以下是三种方法的示例:
**1. 使用while循环:**
```python
sum = 0
num = 1
while num <= 500:
if num % 3 == 0 or num % 5 == 0:
sum += num
num += 1
print("和为:", sum)
```
**2. 使用do-while模拟(实际上不需要,因为Python不支持,这里仅作示意):**
```python
# Python不直接支持do-while,但我们可以通过设置一个条件变量来达到类似效果
condition = True
total = 0
i = 1
while condition:
if i % 3 == 0 or i % 5 == 0:
total += i
i += 1
condition = i <= 500
print("和为:", total)
```
**3. 使用for循环:**
```python
total = sum(i for i in range(1, 501) if i % 3 == 0 or i % 5 == 0)
print("和为:", total)
```
以上三种方法都会计算出符合条件的数并求其和。
求500以内能被3整除或能被5整除的数的和。(分别用while、do while、for编写程序)
while:
```python
i = 1
sum = 0
while i <= 500:
if i % 3 == 0 or i % 5 == 0:
sum += i
i += 1
print(sum)
```
do while:
Python中没有do while语句,可以通过while True和break来实现:
```python
i = 1
sum = 0
while True:
if i > 500:
break
if i % 3 == 0 or i % 5 == 0:
sum += i
i += 1
print(sum)
```
for:
```python
sum = 0
for i in range(1, 501):
if i % 3 == 0 or i % 5 == 0:
sum += i
print(sum)
```
