How to keep 2 decimal even if it's .00

Question

I've been working on this assignment for one of my class and I can't figure out how to round to 2 decimal even if it's .00

I'm printing a table and it just look's weird here's my result :

             1           10000.0             600.0           10600.0
             2           10600.0             636.0           11236.0
             3           11236.0            674.16          11910.16
             4          11910.16            714.61          12624.77
             5          12624.77            757.49          13382.26
             6          13382.26            802.94          14185.19
             7          14185.19            851.11           15036.3
             8           15036.3            902.18          15938.48
             9          15938.48            956.31          16894.79
            10          16894.79           1013.69          17908.48

I print a list of item that I round to 1 for [0] and to 2 for the rest (Sorry some of the var are in french XD)

for n in i_liste_l:
    if n == i_liste_l[0]:
        n = int(round(n,0))
        i_liste_l[0] = n
    else:
        index_i = int(i_liste_l.index(n))
        i_liste_l[index_i] = float(round(n,2))
i = i+1

print('{:>{width}}{:>{width}}{:>{width}}{:>{width}}'.format(*i_liste_l,width = indent))

For the purposes of the question I'm-a filling in some of the values:

print('{:>{width}}{:>{width}}{:>{width}}{:>{width}}'.format(1.2, 1, 4.32, 65.3, width=7))
#>>>     1.2      1   4.32   65.3

You want the .Nf formatter:

print('{:>{width}.2f}{:>{width}.2f}{:>{width}.2f}{:>{width}.2f}'.format(1.2, 1, 4.32, 65.3, width=7))
#>>>    1.20   1.00   4.32  65.30

[In this odd section of the docs](http://docs.python.org/2/library/string.html#format-string-syntax). – Veedrac Sep 26 '13 at 02:00

You can use:

print('%5.2f' % 1.0)

to print

 1.00 # a space in front, 4 characters for the numbers, total 5

The `.format()` syntax is considered to be the way to go for string formatting now as its more precise and in depth. – Sep 26 '13 at 01:51

Even if it wasn't, SKTLZ is *already* using `.format`. Why use another format type on top of that? – Veedrac Sep 26 '13 at 01:53
what is SKTLZ? can you explain more? – justhalf Sep 26 '13 at 02:02

SKTLZ is the name of the OP (original poster). It's a username. – SethMMorton Sep 26 '13 at 02:25

You need to use "%.2f"

Example -

>>> x = 10.0/2
>>> print x
5.0
>>> print "%.2f" % x
5.00
>>> x = 5.0/2
>>> print "%.2f" % x
2.50
