That means that the program reads each text file three times. You can use the walrus operator to avoid the repetition:Python wc.py import pathlib import sys for filename in sys.argv[1:]: path = pathlib.Path(filename) counts = ( (text := path.read_text()).count("\n"), # ...

we use the “ + “ operator. This is because- for int class and str class “ + “ operator is overloaded. Thus Operator Overloading means that the same built-in operator or function shows various behavior for different class objects. ...
Different programming languages support ternary operators, and Python is one of them. Users can term the ternary operators as conditional expressions that help to insert conditions in a Python program. Though, in Python, a conditional operation has the lowest preference of all Python operations. Stil...

notis a unary operator which means it takes only one input value. It can be used with any boolean expression or Python object. Using not with different data types notwith Different Data Types Using not with conditional statements Let’s see how the not operator in Python works with the diffe...

As we can see from the output above, "TutorialsPoint" in the list evaluates to True. This indicates that the value "TutorialsPoint" can be found within the list.The term "bigdata" in the list evaluates to False. This means that the value "bigdata" was not found in the list....
It givesfalsefor 1, because here 1 meanstrueand 0 meansfalse. So simply, if we apply one more not operator in front of this, it will becomedouble notand will give the reverse value of (!expression). As seen above, (!false) will givetrue, but (!!false) will givefalse. ...
