Dictionary lists Oddity or bug?

Question

Python

The task was like this ...
you need to sort the list of dictionaries and
leave only dictionaries with the country Russia there

x = "Россия"
geo_logs = [
    {'visit1': ['Москва', 'Россия']},
    {'visit2': ['Дели', 'Индия']},
    {'visit3': ['Владимир', 'Россия']},
    {'visit4': ['Лиссабон', 'Португалия']},
    {'visit5': ['Париж', 'Франция']},
    {'visit6': ['Лиссабон', 'Португалия']},
    {'visit7': ['Тула', 'Россия']},
    {'visit8': ['Тула', 'Россия']},
    {'visit9': ['Курск', 'Россия']},
    {'visit10': ['Архангельск', 'Россия']},
    {'visit11': ['Минск', 'Беларусь']},
    {'visit12': ['Париж', 'Франция']}
]

for element in geo_logs:
    for visit, country in element.items():
        if country[1] != x:
            geo_logs.remove(element)
print(geo_logs)

I wrote a code which in my view should simply remove elements that do not contain "Russia", but it does not remove for me, not only that, but also that which contains "France"

Can someone explain what's wrong and why it happens?

Answer 1

You can't iterate over a list and remove elements at the same time. Iterate over the copy and remove from the original array.
for element in geo_logs[:]:
