Data types

In Python, like in most programming languages, you can store objects of different types. But it's important to differentiate them in terms of computer memory. There are the following data types in Python:

Text Type: str
Numeric Types: int, float, complex
Sequence Types: list, tuple, range
Mapping Type: dict
Set Types: set, frozenset
Boolean Type: bool
Binary Types: bytes, bytearray, memoryview

Do not dig deep into all of those data types, as for now, we don't need that. We will consider every type in future chapters.

If you have a variable which you want to check its type, use the type() function. Do not forget to use the print function, so Python will print the result for us. For example,


              1234
            
# create some variable
var = (1,2)
# check variable type
print(type(var))

Task

Check the types of variables days and sec_in_hour, defined in the code.
