Actually it is not a function, it is an operation (%).

>>> name, age = 'Michael', 30

My name is Michael and I am 30 years old.

Take a look at the Library Reference Manual, Section 2.1.5.1 "More String
Operations" (http://www.python.org/doc/current/lib/typesseq-strings.html).

Think not, in the standard distribution. A few years back someone
contributed a C module (Steve Clift, from Tasmania, 1995), and you can
find it under contrib/Misc on ftp.python.org. Seems to me there may
have been other efforts along these lines, too.

this emulates the C-function sprintf and not scanf.
What Joacim is looking for is something like raw_input :-)

# -----------------------------------------
aString = raw_input("Give me input :")
print aString

Hi,

Try very old module named sscanf sources in
ftp.python.org/pub/python/contrib/misc/sscanf.c and sscanf.README
#--snip--
import sscanf
fmt='My name is %s and I am %d years old.'
data=('Michael', 30)
result=fmt %data
print result
print sscanf.sscanf(result,fmt)
#/--snip--

output:
My name is Michael and I am 30 years old.
['Michael', 30]

print raw_input("Give me input :") # This seems much easier!
