startswith() function

[milo204]

hi, im new to coding hence i have a rather simple problem!
im trying to sort a list of cities, so that for cities that start with a letter greater than Q, the city name is removed from the list.
My code runs but i dont seem to get the correct output.
How can i specify startswith greater than Q?
many thanks for your help.

visited_cities = ["New York", "Shanghai", "Munich", "Toyko", "Dubai", "Mexico City", "São Paulo", "Hyderabad"]
sorted_cities=sorted(visited_cities)
print(sorted_cities)

for x in sorted_cities:
    if x>="Q":
        sorted_cities.remove(x)
    else:
        pass
print(sorted_cities)
