A string and an integer to appear in tuple (python 2.7)

[Jiewei Huang]

Hi all,

I'm currently stuck at this question on 

Writing a function len_str that takes a string as an argument and returns a pair consisting of the length of the string and the string itself. 

Example: len_str('Meaning of life') should return the tuple (15, 'Meaning of life').


I can only think of this :

len_str = ('welcome to life' )

print (len(len_str,), len_str)


However that not an correct answer I need to make a def len_str but I can't seen to get it right.
