Python: Passes argument(s) to a function

Python Class ( Basic ): Exercise-6 with Solution

Write a Python function student_data () which will print the id of a student (student_id). If the user passes an argument student_name or student_class the function will print the student name and class.

Sample Solution:

Python Code:

def student_data(student_id, **kwargs):
    print(f'\nStudent ID: {student_id}')
    if 'student_name' in kwargs:
        print(f"Student Name: $ {kwargs['student_name']}")
    
    if 'student_name' and 'student_class' in kwargs:
            print(f"\nStudent Name: $ {kwargs['student_name']}")
            print(f"Student Class: $ {kwargs['student_class']}")

 
student_data(student_id='SV12', student_name='Jean Garner')

student_data(student_id='SV12', student_name='Jean Garner', student_class ='V')

Sample Output:

Student ID: SV12
Student Name: $ Jean Garner

Student ID: SV12
Student Name: $ Jean Garner

Student Name: $ Jean Garner
Student Class: $ V

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")
