Python: Convert a given list of strings into list of lists
Python List: Exercise - 167 with Solution
Write a Python program to convert a given list of strings into list of lists.
Sample Solution:
Python Code:
def strings_to_listOflists(colors):
result = [list(word) for word in colors]
return result
colors = ["Red", "Maroon", "Yellow", "Olive"]
print('Original list of strings:')
print(colors)
print("\nConvert the said list of strings into list of lists:")
print(strings_to_listOflists(colors))
Sample Output:
Original list of strings: ['Red', 'Maroon', 'Yellow', 'Olive'] Convert the said list of strings into list of lists: [['R', 'e', 'd'], ['M', 'a', 'r', 'o', 'o', 'n'], ['Y', 'e', 'l', 'l', 'o', 'w'], ['O', 'l', 'i', 'v', 'e']]

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")
