Python: Print all the attributes and their values of instances
Python Class ( Basic ): Exercise-12 with Solution
Write a Python class named Student with two instances student1, student2 and assign given values to the said instances attributes. Print all the attributes of student1, student2 instances with their values in the given format.
Input values of the instances:
student_1:
student_id = "V12"
student_name = "Ernesto Mendez"
student_2:
student_id = "V12"
marks_language = 85
marks_science = 93
marks_math = 95
Expected Output:
student_id -> V12
student_name -> Ernesto Mendez
student_id -> V12
marks_language -> 85
marks_science -> 93
marks_math -> 95
Sample Solution:
Python Code:
class Student:
school = 'Forward Thinking'
address = '2626/Z Overlook Drive, COLUMBUS'
student1 = Student()
student2 = Student()
student1.student_id = "V12"
student1.student_name = "Ernesto Mendez"
student2.student_id = "V12"
student2.marks_language = 85
student2.marks_science = 93
student2.marks_math = 95
students = [student1, student2]
for student in students:
print('\n')
for attr in student.__dict__:
print(f'{attr} -> {getattr(student, attr)}')
Sample Output:
student_id -> V12 student_name -> Ernesto Mendez student_id -> V12 marks_language -> 85 marks_science -> 93 marks_math -> 95

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")
