I'm asking if I can go "a = 1" and then later reassign it to "a = "Foo" " or not

[Putnam]

Code: [Select]

a=5

print(a)

a='five'

print(a)

just put this into repl.it

and since I'm not that kind of ass, the answer is yes

[Rose]

My mind cannot accept that.

Do variables in Python have dynamic type?

The answer is, yes, they do. It's one of the strengths of Python! It also has ducktyping and strong typing. The former is probably beyond your current progress in Python right now, but the latter is easy to understand: you can't arbitrarily, say, add two differently typed variables together. 1 + "5" doesn't equal 6 nor 15, unlike Javascript.

[Rose]

C# will make that into "15",as a string,and won't let you assign strings to int variables

[miauw62]

I don't really like duck typing but that's probably since it'd seem like that would result in runtime errors when you change variables of something rather than compiletime errors.
It's probably a stupid reason though.

[Squeegy]

Dynamic types have their strengths and weaknesses. I actually like Java's non-dynamic variable typing, as I mentioned earlier in the thread, for some instances. Frankly, putting multiple types in a variable is bad practice anyway, because you might put it through functions that do need a specific type, which would crash the program if you weren't extremely careful. Those kinds of bugs can be very hard to root out in a large codebase.

I've never actually used the dynamic type feature of Python. It does seem kind of strange, but I suppose it has its place.

I do like duck typing, however. Mostly because it saves having to type int (13) instead of just 13.

I've never actually used the dynamic type feature of Python. It does seem kind of strange, but I suppose it has its place.

Code: [Select]

foo = load_string_from_external_source()
foo = int(foo) if foo.isdigit() else 0

It's a fairly common paradigm in the code I work on - we do lots of log parsing.

[Orange Wizard]

Well, there you go then.

See, basically what you're doing here is this:

Code: [Select]

int foo = int(load_string_from_external_source())

It can't be anything other than an integer, so what's the point of dynamic type? It just encourages sloppy coding.

If it's a duck, then say it's a duck. It's three to six letters out of your day.

This

Code: [Select]

int foo
has no meaning in Python.

[Mephisto]

See, basically what you're doing here is this:

It's a contrived example.

If there's one thing I've learned working in a mixed Python/.NET shop, it's that people have ideological beliefs about this that verge on religion. I'm not saying you are one of them, but it's futile for me to try to convince anyone.

[Squeegy]

This

Code: [Select]

int foo
has no meaning in Python.

No shit, that's the point. Python has duck typing. Java doesn't. "int foo" means something in Java, and it's more precise and elegant.

[Parsely]

Code: [Select]

start

num firstOperand
num secondOperand
num myAnswer

input firstOperand
input secondOperand

call multiplyBot()
     myAnswer = firstOperand * secondOperand
     display myAnswer

endIs this how modules work? It's just pseudo code, so I know there's no "right" way to do it, but is this logic functional? Does it make sense?

Task is to create a module that has two input parameters.
