Python: Display each element vertically of a given list, list of lists
Python List: Exercise - 168 with Solution
Write a Python program to display vertically each element of a given list, list of lists.
Sample Solution:
Python Code:
text = ["a", "b", "c", "d","e", "f"]
print("Original list:")
print(text)
print("\nDisplay each element vertically of the said list:")
for i in text:
print(i)
nums = [[1, 2, 5], [4, 5, 8], [7, 3, 6]]
print("Original list:")
print(nums)
print("\nDisplay each element vertically of the said list of lists:")
for a,b,c in zip(*nums):
print(a, b, c)
Sample Output:
Original list: ['a', 'b', 'c', 'd', 'e', 'f'] Display each element vertically of the said list: a b c d e f Original list: [[1, 2, 5], [4, 5, 8], [7, 3, 6]] Display each element vertically of the said list of lists: 1 4 7 2 5 3 5 8 6

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")
