Comparing things in Python using type cast

Question

>>> print(type(float)==type(str))
True

Why is it true?

Because both float and str are types in Python, so both type(float) and type(str) result in type (the type of all type objects in Python). — javidcf

It didn't occur to you to look at type(float) and type(str) and see what they are? — molbdnilo

It's not clear where exactly you believe there is any type casting. — molbdnilo

The function type did the following task:

With one argument, return the type of an object. The return value is a type object and generally the same object as returned by object.class.

str and float are built-in data types of python. So your code works like this:

print(type(str))   # <class 'type'>
print(type(float)) # <class 'type'>

If you want to get the desired result, you can use the following code:

s = "test"
f = 3.0
print(type(s)==type(f)) # false

This happens because type(float) and type(str) are "type" objects

If you need to verify the type of a float value you can do something like this

float_value = 10.3
print(type(float_value) == float) # True

Another example with a string:

string_value = "hi"
print(type(string_value) == str) # True
