I need to know what the command is for setting a specific set of decimal places in an answer, somewhat like the PHP number_format command.

Here is what I got coming up in my answer....

0.7893948

I need it so it says:

.789

Anyone have an idea of what the code is to perform this?

http://www.daniweb.com/forums/thread162126.html `a=round(0.7893948, 3)` if you only want to print it so, you can do `print "%.3f" % 0.7893948` You can use this also to prepare result as string `s= "%.3f" % 0.7893948` This answers are with 0 not with . only. That you must check separately for example

``````>>> n=0.7893948
>>> s=round(n,3)
>>> if abs(s)<1: print ("%.3f" % s)[1:]
else: "%.3f" % s``````

That works, but i need to eliminate the zero on the left side of the decimal point. How about do I do that? I have the user entering their attempts to bat and their hits so it isn't an automatic "average", it depends on the input. Sorry for not mentioning earlier.

If it`s a number python will output as 0.something
You can remove 0 by make it a string.

``````>>> n = 0.7893948
>>> print n
0.7893948
>>> n = str(n)
>>> n
'0.7893948'
>>> n = n.replace('0', '')
>>> n
'.7893948'
>>> #if we make it an integer(float) again,it will output the 0
...
>>> n = float(n)
>>> n
0.78939479999999995
>>> import re
>>> re.sub('^0+', '', '0.7893948')
'.7893948'
>>>``````

Maybe you have to think diffrent i dont think that 0 will be a problem.
Post you code if you dont get it to work,so can we look at it.

As I wrote before like this (python 2)

s=number to convert

``````>>> s=0.345
>>> if abs(s)<1: a=("%.3f" % s)[1:]
else: a= ("%.3f") % s

>>> print a
.345
>>>``````

It still still a string tonyjv.
Use this to check type(a)

Just a and enter.
'.345'

If he shall use it to calulate,he need it to make it a float.
a + a
'.345.345'

Except for this small thing

``````>>> float(.345)
0.34499999999999997``````

Not in three decimals as long as it is not string.

Yes off course,i did the same in my code if look at my post.

If it`s a number python will output as 0.something

If you make it a integer/float then the "0. " is there.
That why i said if 0 shall be removed make it a string.
