Python re - running a program from the top without while

Question

I wanted to ask,
Is there a way that you can re - run any sort of program on Python 3.x or 2.x without the need for a while loop?

For instance, is there any block of code that I can use to do this:

if user says yes:
    re - run code from top
else:
    end program

For instance, take this example:

output Hello what would you like to do?
     if user says internet
           response = go to internet.
     if response = true
           go to start.
     else
           end program

def internet
     open web page.
     output Would you like to do anything else?
     if input is yes
          return True
     else
          return False

Thanks, Judy.

Note, the code above is a mock - up.

Answer 1

This works...

>>> from itertools import count
>>> c = count()
>>> for i in c:
...   i = input("what is your input? ")
...   if str(i) == "internet":
...     print "internet"
...   elif i == True:
...     continue
...   else:
...     break
... 
what is your input? True
what is your input? "internet"
internet
what is your input? "foo"
>>> 

But it's still much better as a while loop.

Answer 2

The while is actually the best and cleanest solution here. Remember to place all re-usable functionality in functions or classes. Eg:

def main():
    while True:
        fun()
        ask user
        if user says no:
            break

def fun():
    # your functionality goes here

if __name__ == "__main__":
    main()

Answer 3

while user says no:
    if user says yes:
        do stuff
        break

This gets rid of one of the statements.

Answer 4

You can restart the execution of a script with os.exec*()

Hope this helps!
