inserting a value every other letter in a string -python

Having some issues trying to solve this. The goal is to insert a value n in every other letter in the provided string a.

def insert(a,n):
    k = n
    P = 1
    res = list(''.join(i + k * (P%1==0)
    for P, i in enumerate(a)))
    return str(res)
insert('My name is Pamela', 'x')

the return that I'm getting looks like this

['M', 'x', 'y', 'x', ' ', 'x', 'n', 'x', 'a', 'x', 'm', 'x', 'e', 'x', ' ', 'x', 'i', 'x', 's', 'x', ' ', 'x', 'P', 'x', 'a', 'x', 'm', 'x', 'e', 'x', 'l', 'x', 'a', 'x']

How can I make this come as one string instead of different strings?

If you wanted to insert 'x' between each 2 letters in a, but not at the very end, then this is what you want to write :

def insert(a, n):
    return n.join(a)

print(insert('My name is Pamela', 'x')) 
#Mxyx xnxaxmxex xixsx xPxaxmxexlxa

Try:

fin = ""
return fin.join(res)

This should combine the string.

Returns:

Mxyx xnxaxmxex xixsx xPxaxmxexlxax

Here's a simpler way solution:

def insert(a, n):
    res = ''.join(x + y for x, y in zip(a, n * len(a)))
    return res
print(insert('My name is Pamela', 'x'))

Result:

Mxyx xnxaxmxex xixsx xPxaxmxexlxax

n * len(a) creates the string nnnn... with the same length as a & zip turns the two strings into pairs of one character from each string. Then join turns that into a string.

You can simply use ''.join:

def insert(a, n):
    return ''.join(l + n for l in a)

print(insert('My name is Pamela', 'x'))

Output:

Mxyx xnxaxmxex xixsx xPxaxmxexlxax
