trimming spaces in string python

a = "      yo!      "
b = a.strip() # this will remove the white spaces that are leading and trailing

Here is what the above code is Doing:
1. We create a variable called a and set it equal to a string with leading and trailing spaces.
2. We create a variable called b and set it equal to the variable a with the leading and trailing spaces removed.
3. We print the variable b.
