String Format Printing With Python3: How To Print From Array?

Python3 has the super string.format printing: '{} {}'.format('one', 'two') If my strings are in an array, one way would be to type them out: a = ['one','two'] '{} {}'.format(a[0],

Solution 1:

Use unpacking to expand the array during the function call.

print(hex_string.format(*letters))

Output:

            _____
           /     \
          /       \
    ,----(    1    )----.
   /      \       /      \
  /   2    \_____/   3    \
  \        /     \        /
   \      /       \      /
    )----(    4    )----(
   /      \       /      \
  /        \_____/        \
  \   5    /     \   6    /
   \      /       \      /
    `----(    7    )----'
          \       /
           \_____/

Solution 2:

Try unpacking the elements of the list using * as following. For example, printing would look like

print ('{} {}'.format(*a))
# one two

Solution 3:

Use the * notation for lists:

print(hex_string.format(*letters))
