4 min readIn Python, you can print even numbers by using loops and conditional statements. Here's an example code that prints even numbers from 1 to a given limit: # Define the limit limit = 20 # Iterate through numbers from 1 to limit for num in range(1, limit+1): # Check if the number is even if num % 2 == 0: # Print the even number print(num) In this code, we use a for loop to iterate through the range of numbers from 1 to the given limit.
