Python: Generate a list and tuple with comma-separated numbers

Python Basic: Exercise-6 with Solution

Write a Python program which accepts a sequence of comma-separated numbers from user and generate a list and a tuple with those numbers.

Sample data: 3, 5, 7, 23

Python list:

A list is a container which holds comma separated values (items or elements) between square brackets where items or elements need not all have the same type. In general, we can define a list as an object that contains multiple data items (elements). The contents of a list can be changed during program execution. The size of a list can also change during execution, as elements are added or removed from it.

Python tuple:

A tuple is container which holds a series of comma separated values (items or elements) between parentheses such as an (x, y) co-ordinate. Tuples are like lists, except they are immutable (i.e. you cannot change its content once created) and can hold mix data types.

Sample Solution:-

Python Code:

values = input("Input some comma seprated numbers : ")
list = values.split(",")
tuple = tuple(list)
print('List : ',list)
print('Tuple : ',tuple)

Sample Output:

Input some comma seprated numbers : 3,5,7,23                       
List :  ['3', '5', '7', '23']                                      
Tuple :  ('3', '5', '7', '23')

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")
