Problem Description

When executing code, Spyder just opens a new console instead of executing the code. Other code works, just this snippet does not.

What steps reproduce the problem?

1. Run the following piece of code:

from datetime import datetime

def previous_quarter(month, year):
    quarters = {
            1: [1, 2, 3],
            2: [4, 5, 6],
            3: [7, 8, 9],
            4: [10, 11, 12]
            }
    for q in quarters:
        if month in quarters[q]:
            print(q)
            exit(1)

    return month, year

d = datetime.now().day
m = datetime.now().month
y = datetime.now().year

pq = previous_quarter(m, y)

1. In above code, the problem is reproduced even if the last 4 statements are run separately (using F9), after the previous statements are run. If everything is executed together, the issue seems to persist.

What is the expected output? What do you see instead?

Expected output is either an error statement, or the printed numeric value of variable “q”, followed by a forced exit.

I can reproduce this, but I don’t think that it’s a bug. That’s what exit(1) does, it closes the console. That’s why Spyder starts a new one.

I think in this case break is what you are looking for not exit(). https://docs.python.org/3/tutorial/controlflow.html#break-and-continue-statements-and-else-clauses-on-loops

Hi,

Sorry about that. Thank you for pointing it out!
