How to convert a string into an integer

[yinglcs]

Can you please tell me why the following code does not work in python?
My guess is I need to convert 'count' from a string to an integer. How
can I do that?
And my understanding is python is a dynamic type language, should
python convert it for me automatically?

count = sys.argv[2]
for i in range(count):
#do some stuff

Thank you.

for i in range(int(count)):

You are confusing dynamic typing with weak typing. Weakly typed
languages (such as BASIC perform) such implicit conversions.

However, Python is dynamically and strongly typed.

With dynamic typing, the type information resides with the actual
object and not with the name referring to it. That simply means that
the type cannot be determined till the object is actually created (i.e
till runtime). But once created, the object does have a type.

So you will need to explicitly convert yourself. In this case with
int_value = int(string_value)
