Converting Float to Dollars and Cents

Question

First of all  I have tried this post  among others   Currency formatting in Python   It has no affect on my variable   My best guess is that it is because I am using Python 3 and that was code for Python 2    Unless I overlooked something  because I am new to Python    I want to convert a float  such as 1234 5  to a String  such as   1 234 50    How would I go about doing this   And just in case  here is my code which compiled  but did not affect my variable   money   float 1234 5  locale setlocale locale LC ALL      locale currency money  grouping True    Also unsuccessful   money   float 1234 5  print money   output is 1234 5       2f   format money  print money   output is 1234 5

Building on  JustinBarber s example and noting  eric frederich s comment  if you want to format negative values like - 1 000 00 rather than  -1 000 00 and don t want to use locale   def as currency amount       if amount  gt   0          return       2f   format amount      else          return  -     2f   format -amount

In python 3  you can use   import locale locale setlocale  locale LC ALL   English United States 1252    locale currency  1234 50  grouping   True     Output    1 234 50

In Python 3 x and 2 7  you can simply do this    gt  gt  gt        2f   format 1234 5    1 234 50    The    adds a comma as a thousands separator  and the  2f limits the string to two decimal places  or adds enough zeroes to get to 2 decimal places  as the case may be  at the end

Personally  I like this much better  which  granted  is just a different way of writing the currently selected  best answer     money   float 1234 5  print       format money     2f      Or  if you REALLY don t like  adding  multiple strings to combine them  you could do this instead   money   float 1234 5  print    0   format format money     2f       I just think both of these styles are a bit easier to read    -    of course  you can still incorporate an If-Else to handle negative values as Eric suggests too

you said that    mony   float 1234 5  print money        output is 1234 5       2f   format money  print money    did not work     Have you coded exactly that way  This should work  see the little difference    money   float 1234 5        next you used format without printing  nor affecting value of  money  amountAsFormattedString         2f   format money  print  amountAsFormattedString
