In this tutorial, you'll explore Python's __pycache__ folder. You'll learn about when and why the interpreter creates these folders, and you'll customize their default behavior. Finally, you'll take a look under the hood of the cached .pyc files.
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
object.__hash__(self) Called by built-in functionhash()and for operations on members of hashed collections includingset,frozenset, anddict.__hash__()should return an integer. The only required property is that objects which compare equal have the same hash value; it is advised to somehow m...
What is the correct way to open a file in Python? How do you define a tuple in Python? Which operator is used for 'not equal to' in Python? In Python, what is the purpose of the 'if' statement? What is the result of '3 + 5' in Python? Which Python function is used ...
in the instruction set.And it just goes linearly,instruction by instruction.There might be one particular instruction that does some sort of test.It's going to say,is this particular value greater or equal to or the same as this other particular value?That's a test.And the test is going...
Python decorated_func=decorator(decorated_func) Here’s an example of how to build a decorator function to add new functionality to an existing function: Python >>>defadd_messages(func):...def_add_messages():...print("This is my first decorator")...func()...print("Bye!")...return_...
that you want to store a value on the right side of the equal sign into the variable on the left side. for example, in python, the statement x = 10 assigns the value 10 to the variable x. this allows you to manipulate and work with data in your programs. why is the equal sign ...
ValueError:notenoughvaluestounpack(expected2, got0) The syntax which allows a comma separated series of names on the left to unpack the value on the right is known assequence unpackingin python. The reason MockObject is incompatible with sequence unpacking is due to a limitation of operator ove...
This means that Python 2.7 will remain in place for a long time, providing a stable and supported base platform for production systems that have not yet been ported to Python 3. The full expected lifecycle of the Python 2.7 series is detailed in PEP 373. Some key consequences of the long...
We may verify that the value of __name__ is equal to "__main__" to stop the behaviour occurring which we saw in the previous section.In this manner, the Python file's code inside the if condition is only run when it is directly called rather than when it is imported as a module...
