Identify if the value being printed is float, string or int

Question

In python it is possible to make an impression of several types of variables using the print. Take an example:

print(3.4, "hello", 45);

Or individually.

print(3.4);
print("hello");
print(45);

How is it possible to identify if the value being printed is of the type float, string or int?

Answer 1

To know the type/class we can do (type):

print(type(3.4), type("hello"), type(45)) # <class 'float'> <class 'str'> <class 'int'>

To filter only the part of the float, str, int can:

print(type(3.4).__name__, type("hello").__name__, type(45).__name__) # float str int

For checks can use and is more direct isinstance(var, (objs,)):

if isinstance(3.4, float):
    # True, e float

You can even check if it belongs to one of several types/classes that enter as argument within a tuple:

if isinstance(3.4, (float, str)):
    # True, e float ou string

Answer 2

Use the function type

print(type(3.4), type("hello"), type(45))

>> <class 'float'> <class 'str'> <class 'int'>
