Python | Add an item at an alternate position in the list

Python Methods and Functions

Method: Using join () + list ()
This method can be used to solve this problem in one line. In this case, we simply concatenate all the elements one at a time to the target element and then convert back to a list using list () .

# Python3 code to demonstrate how it works
# Add an element at an alternative position in the list
# using join ( ) + list ()

 
# initialize the list

test_list = [ ' a' , 'b' , 'c' , ' d' , 'e' , 'f' ]

  
# print original list

print ( "The original list is:" + str (test_list))

  
# initialize ele

ele = '#'

 
# Add an element at an alternative position in the list
# using join () + list ()

res = list (ele.join (test_list))

  # print result

print ( "List after alternate addition:" + str (res))

Output:

 The original list is: ['a',' b', 'c',' d', 'e',' f'] List after alternate addition: ['a',' # ',' b ',' # ',' c', '#', 'd',' # ',' e', '#', 'f']
