Python: Get a single string from two given strings, separated by a space and swap the first two characters of each string

Python String: Exercise-5 with Solution

Write a Python program to get a single string from two given strings, separated by a space and swap the first two characters of each string.

Python String Exercises: Get a single string from two given strings, separated by a space and swap the first two characters of each string

Sample Solution:-

Python Code:

def chars_mix_up(a, b):
  new_a = b[:2] + a[2:]
  new_b = a[:2] + b[2:]

  return new_a + ' ' + new_b
print(chars_mix_up('abc', 'xyz'))

Sample Output: 

xyc abz

Previous: Write a Python program to get a string from a given string where all occurrences of its first char have been changed to '$', except the first char itself.
Next: Write a Python program to add 'ing' at the end of a given string (length should be at least 3). If the given string already ends with 'ing' then add 'ly' instead. If the string length of the given string is less than 3, leave it unchanged.

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")
