Write a Python script that determines whether each of the
columns of an alignment is conserved. The alignment length
will be exactly three and there are no gaps. For example the
input may be

>A
ACG
>B
CCG
>C
ACG
>D
TCA

Your program should print "Conserved" or "Not conserved" depending
upon the column. For the example above your program should output

"Not conserved"
"Conserved"
"Not conserved"

Every sequence will be exactly of length three but there may be many
sequences (as many as 100).
