编写一个Python函数,接收一个整数列表作为参数,返回列表中所有偶数的平均值。```pythondef average_even(numbers):evens = [x for x in numbers if x % 2 == 0]if len(evens) == 0:return 0return sum(evens) / len(evens)numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]pri...
In this tutorial, we are going to show How to print even numbers using one line python code. We have added the video tutorial and the source code of the program
#any()示例defis_even(num):returnnum%2==0numbers=[1,3,5,7,8]print(any(is_even(num)fornuminnumbers))# 输出:True,因为存在偶数 #all()示例print(all(is_even(num)fornuminnumbers))# 输出:False,因为存在奇数 1. 2. 3. 4. 5. 6. 7. 8. 9. 11. 实际场景应用 在实际开发中,any()和...
print(f"{num}是素数")break```### 五、高级技巧：嵌套与推导式1. **嵌套结构**：```python# 嵌套循环实现乘法表for i in range(1,10):for j in range(1,i+1):print(f"{j}x{i}={i*j}", end='\t')print("")```2. **推导式中的条件**：```python# 带条件的列表推导式numbers =...
[1, 2, 2, 3, 4, 4, 4, 5] unique_numbers = {x for x in numbers} print(unique_numbers) # 输出:{1, 2, 3, 4, 5} #获取一个句子中所有不重复的单词 sentence = "apple banana apple cherry banana" unique_words = {word for word in sentence.split()} print(unique_words) # 输出:...

Since Python rounds ties to the nearest even number, you would expect round(2.675, 2) to return 2.68, but it returns 2.67 instead. This error is the result of a floating-point representation error, not a bug in round().Dealing with floating-point numbers can be frustrating, but this ...
