Wrong usage of "a"

Wrong usage of "a" in the messages:
"'%s' is not a integer"
"Create a address scope"
"Return True if port has as a allowed address pair"
"But if a agent does not report its status"
"a ipv4 link-local address"
"Retrieve and return a extended information about a network"
"It could be a eui-64 address, a random IPv6 address"
"push a elastic-recheck query for it (see below)"
"is not a enforced requirement"
"a ovs_lib.VifPort object"

Should be:
"'%s' is not an integer"
"Create an address scope"
"Return True if port has as an allowed address pair"
"But if an agent does not report its status"
"an ipv4 link-local address"
"Retrieve and return extended information about a network"
