Python: Convert a given list of tuples to a list of strings using map function

Python map: Exercise-17 with Solution

Write a Python program to convert a given list of tuples to a list of strings using map function.

Sample Solution:

Python Code:

def tuples_to_list_string(lst):
    result = list(map(' '.join, lst))
    return result   
colors = [('red', 'pink'), ('white', 'black'), ('orange', 'green')]
print("Original list of tuples:")
print(colors)
print("\nConvert the said list of tuples to a list of strings:")
print(tuples_to_list_string(colors))
names = [('Sheridan','Gentry'), ('Laila','Mckee'), ('Ahsan','Rivas'), ('Conna','Gonzalez')]
print("\nOriginal list of tuples:")
print(names)
print("\nConvert the said list of tuples to a list of strings:")
print(tuples_to_list_string(names))

Sample Output:

Original list of tuples:
[('red', 'pink'), ('white', 'black'), ('orange', 'green')]

Convert the said list of tuples to a list of strings:
['red pink', 'white black', 'orange green']

Original list of tuples:
[('Sheridan', 'Gentry'), ('Laila', 'Mckee'), ('Ahsan', 'Rivas'), ('Conna', 'Gonzalez')]

Convert the said list of tuples to a list of strings:
['Sheridan Gentry', 'Laila Mckee', 'Ahsan Rivas', 'Conna Gonzalez']

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")
