This issue came across when I was trying to statically type Python like this:

maybeFloat: float = 2

But when I'm trying to print the type of the variable doing this:

print(type(maybeFloat))

The console logs this:

<class 'int'>

What am I doing wrong? What's the purpose of static typing in Python if it is not going to work?

CodePudding user response：

Indeed there is no such thing as static typing in python. var : int = 1 is an annotation. Something only useful as documentation.

Even you can assign any type to a typed variable :

x float = 'I am a float!'

Also the the 'types' does not need to be types:

x: 'hello' # x is a 'hello'

Annotations reside in the __annotations__ variable. So you can use it as a namespace to hold variables

x: 3.14
print(__annotations__[x]) # -> 3.14

Thats not very useful though
