Format specifiers .py

# Format specifiers = {value:flags} format a value based on what flags are inserted


# .(number)f = round to that many decimal places (fixed point)
# :(number) = allocate that many spaces
# :03 = alllocate and zero pad that many spaces
# :< = left justify
# :> = right justify
# :^ = center align
# :+ = use a plus sign to indicate +ve value
# := = place sign to leftmost position
# :  = insert a space before positive numbers
# :, = comma separator
# Note that mixture of 2 or more flags is allowed based on what you are looking for or what you need to achieve
