Write a Python program that asks the user for an input sequence and then searches for
the exact same sequence in dna.txt given in FASTA format. If the sequence is found in
the file then the program should print "Yes" and "No" otherwise.

For example if the input in the file dna.fasta is

>A
ACCGTA
>B
ACCGTAACCTTG
>C
TCCTATAA
>D
ACC
>E
ACACAGTTTGCGCGCGCGGGG
>F
GCTTTAAAAAGGCAA
>G
ATGTA
>H
GCGCCCCCCA

and the user enters the sequence ATGTA on the keyboard then the program should
print "Yes". If the user enters "AACC" then the program should print "No". 

Your program should work for any input file and not just this example.
Submit a hardcopy in class on Sept 30th.

Start with the code below.

####Read data from file####
f = open("dna.txt", "r")
data = f.readlines()

####Remove newlines from data####
for i in range(0, len(data), 1):
    data[i] = data[i].strip("\n")

query = input("Please enter a DNA sequence:")
