a = "abcdefghijkl"
b = a[0:4] + a[-4:]

Here I have a string called a, variable b is a new string created from slicing and adding the indexes you requested. Does this make sense? First I'm saying give me the first four letters of 'a' which starts at zero and goes to 4 because it doesn't include 4th index. Then I'm adding the last 4 from 'a' by using the negative index which counts from the right. Then by just using : that says give me everything from negative 4 to the end of the string. I hope this helps.

You could also just do this without a new variable.

print(a[0:4] + a[-4:])
