Python: Reverse strings in a given list of string values using lambda
Python Lambda: Exercise-41 with Solution
Write a Python program to reverse strings in a given list of string values using lambda.
Sample Solution:
Python Code :
def reverse_strings_list(string_list):
result = list(map(lambda x: "".join(reversed(x)), string_list))
return result
colors_list = ["Red", "Green", "Blue", "White", "Black"]
print("\nOriginal lists:")
print(colors_list)
print("\nReverse strings of the said given list:")
print(reverse_strings_list(colors_list))
Sample Output:
Original lists: ['Red', 'Green', 'Blue', 'White', 'Black'] Reverse strings of the said given list: ['deR', 'neerG', 'eulB', 'etihW', 'kcalB']

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")
