Use string methods to print the following strings. Remember that methods work by
adding the function to the end of the object name using a ., like
mystring = 'Hello World'
print mystring.lower()
'species' in all capital letters'gcagtctgaggattccaccttctacctgggagagaggacatactatatcgcagcagtggaggtggaatgg'
with all of the occurences of 'a' replaced with 'A'" Thank goodness it's Friday" without the leading white space
(i.e., without the spaces before "Thank")'a's in 'gccgatgtacatggaatatacttttcaggaaacacatatctgtggagagg'.
