Python Exercise: Convert a given list of tuples to a list of lists
Python tuple: Exercise-33 with Solution
Write a Python program to convert a given list of tuples to a list of lists.
Sample Solution:-
Python Code:
def test(lst_tuples):
result = [list(el) for el in lst_tuples]
return result
lst_tuples = [(1,2), (2,3), (3,4)]
print("Original list of tuples:")
print(lst_tuples)
print("Convert the said list of tuples to a list of lists:")
print(test(lst_tuples))
lst_tuples = [(1,2), (2,3,5), (3,4), (2,3,4,2)]
print("\nOriginal list of tuples:")
print(lst_tuples)
print("Convert the said list of tuples to a list of lists:")
print(test(lst_tuples))
Sample Output:
Original list of tuples: [(1, 2), (2, 3), (3, 4)] Convert the said list of tuples to a list of lists: [[1, 2], [2, 3], [3, 4]] Original list of tuples: [(1, 2), (2, 3, 5), (3, 4), (2, 3, 4, 2)] Convert the said list of tuples to a list of lists: [[1, 2], [2, 3, 5], [3, 4], [2, 3, 4, 2]]

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")
