How can I create a loop to add spaces between elements of a string in python?-CodePudding

I am looking for a way to add spaces between words in a string until len(string) < n is reached. I've tried this:

string = "you are great"
n = 20
res = []
for i in string:
    if ord(i) == 32 and len(string) < num:
        res = [string   i]

And I want it to add spaces between "you" and "are", and "are" and "great. So it gives me something like this:

res = ["you     are    great"]

But instead I get this

"you are great "

No need of loops:

string = "you are great"
n = 20
a = n - len(string.replace(' ', ''))    # amount of spaces to add
b = string.split()                      # list of words (without spaces)
if a & 1:
    b[0]  = ' '                         # if 'a' is odd, add an extra space to first word
d = (' ' * (a // 2)).join(b)            # concatenate all words with 'a' spaces between them
print(d)

The output is:

"you     are    great"

You code is doing what it is suppose to do but as you can see in the second output it adds a space to your string. The code below is the issue.

Res = [string   i]
