Python - decimal places (putting floats into a string)

Question

I have been using the format:

print \'blah, blah %f\' %variable

to put variables into strings. I heard it was more pythonic than the \'+str

Answer 1

>>> variable = 12
>>> print 'blah, blah %4.3f' %variable
blah, blah 12.000
>>> print 'blah, blah %1.1f' %variable
blah, blah 12.0

Here is the Python Doc Link, please consider:

Since str.format() is quite new, a lot of Python code still uses the % operator. However, because this old style of formatting will eventually be removed from the language, str.format() should generally be used.
