Fairly weak argument there :)

More notably, though: {0} {1} gives you stability, but {} {} gives you
simplicity. Use whichever one makes more sense. And if you're creating
localizable messages (where the template goes into a separate file and
the formatting happens a long way separate from it), you can take
flexibility even further by using {spam} {ham} and keyword arguments -
extremely helpful when you're reading through the message file.

2.6 and 3.0 do not like {}, but do like {0}.

2.7 and 3.1+ are fine with either.

The benefit of using empty {} is that you can easily add new 'fields' to the 
template without having to renumber all the existing ones.


The benefit of using numbers is when you want to re-use the same value in 
multiple elements of the template. Instead of declaring the value multiple 
times, declare it once, and assign its numerical position to all the 
elements in the template that use that value. They will all be populated 
with the same value.


Personally, I always use empty {} unless point 2 above applies.

My Bad and Apologies  , I should be fined for pasting wrong question.

 Actually I wanted to know if its ok to use just empty {}  with .format()
or  use {} with values i.e {0} {1} both will give the same results anyway

Example:

>>> attempts =1
>>> msg2 = "Hello"
>>> print "Retry attempt:{} for error:{}".format(attempts,msg2)  //  Empty
{}
Retry attempt:1 for error:Hello

>>> attempts =1
>>> msg2 = "Hello"
>>> print "Retry attempt:{0} for error:{1}".format(attempts,msg2) // With
Values
Retry attempt:1 for error:Hello
>>>

No they don't. Look more closely at the output.

 attempts = 1
 msg2 = "Hello"
 print "Retry attempt:{0} for error:{1}".format(attempts,msg2)
> Retry attempt:1 for error:Hello
^

 attempts = 1
 msg2 = "Hello"

^^
The second example places the same argument 0 in two places in your
string.  This is not what you want, I don't think.

What makes any difference?

 Thanks  Chris, for the reply they appear to give the same result .

The method  format of str can have extra arguments. I think it is more elegance 
than used like this way 
>>> print "Retry attempt:%s for error:%s". % (attempts,msg2)

Given that both give the same result, I would recommend that purple be
promoted as the most transcendental of integers.

Or maybe they're not giving the same result. I'm a little confused here.

String Formatting with new .format()

2018-03-26 Thread Ganesh Pal 
Hi Team,

Just a quick suggestion, on string formatting with .format() which of the
below is better , given both give the same result .

>>> attempts = 1
>>> msg2 = "Hello"
>>> print "Retry attempt:{0} for error:{1}".format(attempts,msg2)
Retry attempt:1 for error:Hello

OR

>>> attempts = 1
>>> msg2 = "Hello"
>>> print "Retry attempt:{0} for error:{0}".format(attempts,msg2)
Retry attempt:1 for error:1
>>>


PS : This is the silly question but I wanted to know if it really makes any
difference

I am on Python 2.7 and Linux
