Python: Search the numbers (0-9) of length between 1 to 3 in a given string

Python Regular Expression: Exercise-18 with Solution

Write Python program to search the numbers (0-9) of length between 1 to 3 in a given string.

Sample Solution:-

Python Code:

import re
results = re.finditer(r"([0-9]{1,3})", "Exercises number 1, 12, 13, and 345 are important")
print("Number of length 1 to 3")
for n in results:
     print(n.group(0))
	 

Sample Output:

Number of length 1 to 3                                                                                       
1                                                                                                             
12                                                                                                            
13                                                                                                            
345

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]]
