Using "in" operator compare/convert a string to an int

Question

I need to find if an integer is found in a list of strings.

context = ['4', '6', '78']

if category.id in context:

The code above is not working because I compare int(category id) with strings.

I can't use int(context) because context is a list and will give an error.

I can convert category.id to string, but can bad situations appear ?

Using in operator it is possible to convert the strings to int, or I need to use a for loop ?

Answer 1

You could also consider using a list comprehension to convert context to a list of integers.

context_ints = [int(i) for i in context]
if category.id in context_ints:
    ... do stuff ...

If context is guaranteed to be a list of strings that can sensibly be converted to integers, this may be the safest route for you.
