How to Print a Sequence of Prime Numbers in Python
Many programmers struggle to create a function that accurately prints prime numbers in Python. One common problem is printing a list of odd numbers instead. To rectify this issue, a thorough understanding of prime number properties and an alteration to the code are essential.
Prime numbers are only divisible by 1 and themselves. Therefore, the improved code checks divisibility within a range from 2 to the square root of the number (or the number itself if it's smaller). This ensures efficiency and accuracy.
Here's an example using a more optimized and Pythonic syntax:
<code class="python">import math for num in range(2, 101): if all(num % i != 0 for i in range(3, int(math.sqrt(num)) + 1, 2)): print(num)</code>
