    The two common to print a blank line in Python-

    1. The old school way:

      print "hello\n"

    2. Writing the word print alone would do that:

      print "hello"

      print

    You will always only get an indent error if there is actually an indent error. Double check that your final line is indented the same was as the other lines -- either with spaces or with tabs. Most likely, some of the lines had spaces (or tabs) and the other line had tabs (or spaces).

    Trust in the error message -- if it says something specific, assume it to be true and figure out why.

    This is are other ways of printing empty lines in python

    # using \n after the string creates an empty line after this string is passed to the the terminal.
    print("We need to put about", average_passengers_per_car, "in each car. \n") 
    print("\n") #prints 2 empty lines 
    print() #prints 1 empty line

    Don't do

    print("\n")
    

    on the last line. It will give you 2 empty lines.

    You can just do

    print()
    

    to get an empty line.

    Python's print function adds a newline character to its input. If you give it no input it will just print a newline character

    print()
    

    Will print an empty line. If you want to have an extra line after some text you're printing, you can a newline to your text

    my_str = "hello world"
    print(my_str + "\n")
    

    If you're doing this a lot, you can also tell print to add 2 newlines instead of just one by changing the end= parameter (by default end="\n")

    print("hello world", end="\n\n")
    

    But you probably don't need this last method, the two before are much clearer.
