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 out 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.

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:

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
    ]

for x in numbers:
    if x == 237:
        print(x)
        break;
    elif x % 2 == 0:
        print(x)

Sample Output: 

386                                                                                                           
462                                                                                                           
418                                                                                                           
344                                                                                                           
236                                                                                                           
566                                                                                                           
978                                                                                                           
328                                                                                                           
162                                                                                                           
758                                                                                                           
918

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
