How to keep tabs when adding new lines in python

Question

So I'm trying to format a list in Python using the .format() method. I want my output to be as follows

One
    Two
        Three
            Four

However, when I run the following code

if __name__ == '__main__':
    output_str = ''
    my_list = ['One', 'Two', 'Three', 'Four']
    for element in my_list:
        output_str = '{}{}\n\t'.format(output_str, element)
    print (output_str)

It prints

One
    Two
    Three
    Four

Is there a way of making new lines in Python while keeping all tabs made before with .format()? Thanks for answering :)

Works pretty good, Thanks :P. However, I still wonder if there's a way to do it directly with .format() without having to do such tricks — Vectrex28

Yes, the .format() can be used to do the indentation by specifying the tab character as the fill character as follows:

my_list = ['One', 'Two', 'Three', 'Four']

for indent_level, element in enumerate(my_list):
    print("{:\t<{i}}{}".format('', element, i=indent_level))

This would display:

One
    Two
        Three
            Four
