Python: Search some literals strings in a string

Python Regular Expression: Exercise-19 with Solution

Write a Python program to search some literals strings in a string.

Sample Solution:-

Python Code:

import re
patterns = [ 'fox', 'dog', 'horse' ]
text = 'The quick brown fox jumps over the lazy dog.'
for pattern in patterns:
    print('Searching for "%s" in "%s" ->' % (pattern, text),)
    if re.search(pattern,  text):
        print('Matched!')
    else:
        print('Not Matched!')
		

Sample Output:

Searching for "fox" in "The quick brown fox jumps over the lazy dog." ->                                      
Matched!                                                                                                      
Searching for "dog" in "The quick brown fox jumps over the lazy dog." ->                                      
Matched!                                                                                                      
Searching for "horse" in "The quick brown fox jumps over the lazy dog." ->                                    
Not Matched!

Python: Tips of the Day

Merges two or more lists into a list of lists, combining elements from each of the input lists based on their positions

Example:

def tips_merge(*args, fill_value=None):
  max_length = max([len(lst) for lst in args])
  result = []
  for i in range(max_length):
    result.append([
      args[k][i] if i < len(args[k])
	  else fill_value for k in range(len(args))
    ])
  return result
print(tips_merge(['x', 'y'], [1, 2], [True, False])) 
print(tips_merge(['x'], [1, 2], [True, False])) 
print(tips_merge(['x'], [1, 2], [True, False], fill_value = '_')) 

Output:

[['x', 1, True], ['y', 2, False]]
[['x', 1, True], [None, 2, False]]
[['x', 1, True], ['_', 2, False]]
