Python: Create a list by concatenating a given list which range goes from 1 to n

Sample Solution:-

Python Code:

my_list = ['p', 'q']
n = 4
new_list = ['{}{}'.format(x, y) for y in range(1, n+1) for x in my_list]
print(new_list)

Sample Output: 

['p1', 'q1', 'p2', 'q2', 'p3', 'q3', 'p4', 'q4']

Python: Tips of the Day

Creates a list of elements, grouped based on the position in the original lists:

Example:

def tips_zip(*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 fillvalue for k in range(len(args))
   	 ])
 	 return result
print(tips_zip(['a', 'b'], [1, 2], [True, False]))
print(tips_zip(['a'], [1, 2], [True, False]))
print(tips_zip(['a'], [1, 2], [True, False], fill_value = '1'))

Output:

[['a', 1, True], ['b', 2, False]]
[['a', 1, True], [None, 2, False]]
[['a', 1, True], ['1', 2, False]]
