Python: Find smallest and largest word in a given string

Python String: Exercise-79 with Solution

Write a Python program to find smallest and largest word in a given string.

Sample Solution:-

Python Code:

def smallest_largest_words(str1):
    word = "";
    all_words = [];
    str1 = str1 + " ";
    for i in range(0, len(str1)):
        if(str1[i] != ' '):
            word = word + str1[i];  
        else:
            all_words.append(word);  
            word = "";  
          
    small = large = all_words[0];  
   
#Find smallest and largest word in the str1  
    for k in range(0, len(all_words)):
        if(len(small) > len(all_words[k])):
            small = all_words[k];
        if(len(large) < len(all_words[k])):
            large = all_words[k];
    return small,large;

str1 = "Write a Java program to sort an array of given integers using Quick sort Algorithm.";  
print("Original Strings:\n",str1)
small, large = smallest_largest_words(str1)  
print("Smallest word: " + small);  
print("Largest word: " + large);

Sample Output:

Original Strings:
 Write a Java program to sort an array of given integers using Quick sort Algorithm.
Smallest word: a
Largest word: Algorithm.

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")
