In Python, how can I do multiple formats at once:
So I want to make a number have no decimal places and have a thousands separator:
num = 80000.00
I want it to be 80,000
I know I can do these two things serepatly, but how would I combine them:
"{:,}".format(num) # this will give me the thousands separator
"{0:.0f}".format(num) # this will give me only two decimal places
So is it possible to combine these together??
You can combine the two format strings. The comma goes first after the colon:
>>> "{:,.0f}".format(80000.0)
'80,000'
Note that you can also use the free format() function instead of the method str.format() when formatting only a single value:
>>> format(80000.0, ",.0f")
'80,000'
Edit: The , to include a thousands separator was introduced in Python 2.7, so the above conversions don't work in Python 2.6. In that version you will need to roll your own string formatting. Some ad-hoc code:
def format_with_commas(x):
s = format(x, ".0f")
j = len(s) % 3
if j:
groups = [s[:j]]
else:
groups = []
groups.extend(s[i:i + 3] for i in range(j, len(s), 3))
return ",".join(groups)
"{:,.2f}"if you want the two decimal places
