Python: Print all even numbers from a given numbers list in the same order and stop the printing if any numbers that come after 237 in the sequence

Python Basic: Exercise-28 with Solution

Write a Python program to print all even numbers from a given list of numbers in the same order and stop printing any after 237 in the sequence.

Sample numbers list:

numbers = [    
    386, 462, 47, 418, 907, 344, 236, 375, 823, 566, 597, 978, 328, 615, 953, 345, 
    399, 162, 758, 219, 918, 237, 412, 566, 826, 248, 866, 950, 626, 949, 687, 217, 
    815, 67, 104, 58, 512, 24, 892, 894, 767, 553, 81, 379, 843, 831, 445, 742, 717, 
    958,743, 527
    ]

Sample Solution:

Python Code:

# Define a list of numbers.
numbers = [    
    386, 462, 47, 418, 907, 344, 236, 375, 823, 566, 597, 978, 328, 615, 953, 345, 
    399, 162, 758, 219, 918, 237, 412, 566, 826, 248, 866, 950, 626, 949, 687, 217, 
    815, 67, 104, 58, 512, 24, 892, 894, 767, 553, 81, 379, 843, 831, 445, 742, 717, 
    958,743, 527
]

# Iterate through the numbers in the list.
for x in numbers:
    if x == 237:
        print(x)  # Print the number if it's 237.
        break  # Exit the loop if 237 is found.
    elif x % 2 == 0:
        print(x)  # Print the number if it's even.

Sample Output:

386                                                                                                           
462                                                                                                           
418                                                                                                           
344                                                                                                           
236                                                                                                           
566                                                                                                           
978                                                                                                           
328                                                                                                           
162                                                                                                           
758                                                                                                           
918  
237                                                                                                 

Explanation:

The said code defines a list called "numbers" with a set of integers. Then it uses a for loop to iterate through each element in the "numbers" list.

For each iteration, it checks if the current element is equal to 237, if true it prints the current element and exit the loop using the "break" statement.

If the current element is not equal to 237, it checks if the current element is even, if true it prints the current element.

Using this logic, the code will only print the number 237 and even numbers of the list. If 237 was not found in the list, the code will print all the even numbers in the list.
