Python Loop over a Dictionary until i went over x elements

July 25, 2022

Hey i have a Short Question:

I Wanted to Iterate over my Dictionary with 7 Elements inside (Days of the Week)

and wanted to start at x element and loop until i went x elements forward
i thought about a while loop and manually set the current element to the start when reaching the end.

        while x in days_dict:
            final_day = days_dict[x]
            x += 1
            print(final_day)

What would be the best way to go about looping until you went x steps?

My Dictionary Looks like this:

days_dict = {"Monday":0, "Tuesday":1, "Wednesday":2, "Thursday":3, "Friday":4, "Saturday":5, "Sunday":6}



Desired Output for y = 1 and x = 9:

Thursday or 3

>Solution :

First of all, you can’t use an integer to access a dictionary element when the index is a string. You need to swap the index and values: day_dict = {0:'Monday', 1:'Tuesday'...}

Rather than loop, just perform the calculation directly: final_day = day_dict[(y+x) % len(day_dict)]

Anyone else can correct me if I’m wrong – I’m only human
