The information in DNA Is coded in chemical bases adenosine (A) guanine (G) cytosine (C), and thymine (T) We can represent a DNA strand by stringing together the letters representing the appropriate strand. Imagine we are given a list of DNA strands which have arbitrary lengths. Write a single function strand_counter() which takes a list of DNA strands, counts the lengths of each of the words in the list and then calculates and returns the integer maximum_length integer minimum_length, and float average_length 
Then write a program which takes in a user-chosen number of strands of arbitrary length as an input and prints out the calculated information 
Example input 
5 
AT 
ATCGTCOGGT 
TCGCT 
TCGATTCCT 
TTCATCG 
Example output 
The longest strand has length 10. 
The shortest strand has length 2. 
The average length of the strands is 6.6.
