a = 11
b = 57
maxnu = a * b
for i in range(1,maxnu + 1):
if ( i % a == 0 and i % b == 0 ):
ans = i
break
print("最小公倍數:",ans)
```
最小公倍數: 627
```python
num = 3
ans = 1
n = 0
while n <= 5:
n = n+1
ans = ans* n
print("num! = ",ans)
```
num! = 720
實作5:
一個正整數除了1和自己外，無法再被其他數整除，這個數就是質數。 請輸入一正整數，列出此數的所有正因數，並判斷使數字是否為質數
```python
a = 15
p = 1
counter = 0
while p <= a :
if a % p == 0:
counter = counter+1
p = p + 1
if counter > 2 :
ans = "質數"
else :
ans = "合數"
print(a,"質數","合數")
```
15 質數 合數

猜數字遊戲：寫一個程式，隨機選擇一個1到100的數字，然後要求玩家通過輸入猜測該數字，直到猜對為止。使用while迴圈來實現，並在玩家猜對時結束遊戲。
import random
生成隨機數字
target_number = random.randint(1, 100)
guess = None attempts = 0
while guess != target_number: guess = int(input("請猜一個1到100的數字：")) attempts += 1
if guess < target_number:
print("太低了！再猜一次。")
elif guess > target_number:
print("太高了！再猜一次。")
print(f"恭喜！你猜對了，答案是{target_number}。你總共猜了{attempts}次。")
使用者輸入：寫一個程式，要求使用者輸入一個整數，然後使用while迴圈，只有當輸入的數字是正整數時，才停止請求輸入。如果輸入不是正整數，則繼續要求輸入，直到收到正確的輸入。
user_input = None
while not user_input: user_input = input("請輸入一個正整數：") if user_input.isdigit(): user_input = int(user_input) else: user_input = None print("請輸入正確的整數。")
print(f"您輸入了正整數：{user_input}")
倒數計時器：寫一個程式，請求使用者輸入一個正整數作為倒數計時的秒數，然後使用while迴圈從輸入的秒數倒數到0。在每個秒數的間隔打印出剩餘的秒數。
import time
countdown = int(input("請輸入倒數的秒數："))
while countdown > 0:
print(countdown)
#
countdown -= 1
print("時間到！")
累積加法：寫一個程式，要求使用者不斷輸入整數，並使用while迴圈計算這些整數的總和。當使用者輸入0時，停止接受輸入並印出總和。
total = 0
while True: num = int(input("請輸入一個整數（輸入0結束）：")) if num == 0: break total += num
print(f"總和：{total}")
數字猜謎：寫一個程式，在1到10之間選擇一個隨機數字，然後要求玩家通過輸入猜測該數字。使用while迴圈來實現，並提供猜測是太高還是太低的提示，直到猜對為止。
import random
生成隨機數字
target_number = random.randint(1, 10)
guess = None
while guess != target_number: guess = int(input("請猜一個1到10的數字："))
if guess < target_number:
print("太低了！再猜一次。")
elif guess > target_number:
print("太高了！再猜一次。")
print(f"恭喜！你猜對了，答案是{target_number}。")
```python
import random
target_number = random.randint(1, 100)
guess = None
attempts = 0
while guess != target_number:
guess = int(input("請猜一個1到100的數字："))
attempts += 1
if guess < target_number:
print("太低了！再猜一次。")
elif guess > target_number:
print("太高了！再猜一次。")
print(f"恭喜！你猜對了，答案是{target_number}。你總共猜了{attempts}次。")
```
```python
import random
# 生成隨機數字
target_number = random.randint(1, 10)
guess = None
while guess != target_number:
guess = int(input("請猜一個1到10的數字："))
if guess < target_number:
print("太低了！再猜一次。")
elif guess > target_number:
print("太高了！再猜一次。")
print(f"恭喜！你猜對了，答案是{target_number}。")
```
```python
import time
countdown = int(input("請輸入倒數的秒數："))
while countdown > 0:
print(countdown)
#############
countdown -= 1
print("時間到！")
```
```python
total = 0
while True:
num = int(input("請輸入一個整數（輸入0結束）："))
if num == 0:
break
total += num
print(f"總和：{total}")
