Im using a library of functions that some of them print data I need:
def func():
print "data"
How can I call this function and get the printed data into a string?

Answers. You can't use a print inside a FUNCTION.
print just shows the human user a string representing what is going on inside the computer. The computer cannot make use of that printing. return is how a function gives back a value. This value is often unseen by the human user, but it can be used by the computer in further functions.
In Python, we utilize the asterisk operator to repeat a string. This operator is indicated by a “*” sign. This operator iterates the string n (number) of times. The “n” is an integer value.
If you can't change those functions, you will need to redirect sys.stdout:
>>> import sys
>>> stdout = sys.stdout
>>> import StringIO
>>> s = StringIO.StringIO()
>>> sys.stdout = s
>>> print "hello"
>>> sys.stdout = stdout
>>> s.seek(0)
>>> s.read()
'hello\n'
