The elements in the array with True contain all Prime numbers less than or equal to the given number and the elements of the array which is our Prime number. After the above process, we will simply find the sum of the prime numbers. Let's start writing a Python program using the above...
```python #设height=(None, 0),这样就可以选择所有峰值, 或者使用array(如👇)匹配x的大小来反映不同部分的变化条件。 border = np.sin(np.linspace(0, 3 * np.pi, x.size)) peaks, _ = find_peaks(x, height=(-border, border)) plt.plot(x) plt.plot(-border, "--", color="gray") pl...
>>> list1 = [x for x in range(5)] >>> list1 [0, 1, 2, 3, 4] >>> list2 = [0.5 * x for x in list1] >>> list2 [0.0, 0.5, 1.0, 1.5, 2.0] >>> list3 = [x for x in list2 if x < 1.5] >>> list3 [0.0, 0.5, 1.0] 1. 2. 3. 4. 5. 6. 7. 8. 9....
