You are combining a while loop and a recursive call to main in a
redundant way. A while loop without the complication of the
function calling itself makes things easier. By the way, input
returns a string, so you don't need to call "str" on it.
query = input("Please type in your question(press 'Enter' to exit):")
while query!='':
oracle()
count += 1
query = input("Please type in your question(press 'Enter' to exit):"))
When the while loop is finally complete, count will be the number
of times oracle has run. In current Python, pushing the query
into a separate function is a good way to eliminate the verbatim
repetition of code.
def get_query():
return input("Please type in your question(press 'Enter' to exit):")
In main:
query = get_query()
while query!='':
oracle()
count += 1
query = get_query()
You can generalize function-call counting by writing a function
decorator that counts the number of times its function has run,
and then decorate oracle with it, but that pie is higher in the
sky than needed here.
