When we define a variable outside of a function, it is global by default. You don't have to use theglobalkeyword. We use theglobalkeyword to modify (write to) a global variable inside a functi...
Python Keywords Keywords are predefined, reserved words used in Python programming that have special meanings to the compiler. We cannot use a keyword as a variable name, function name, or any other identifier. They are used to define the syntax and structure of the Python language. All the ...
Here is a list of the Python keywords.Enter any keyword to get more help.Falseclass from or None continue global passTruedef if raise and del import return as elif in try assert else is while async except lambda with await finally nonlocal yield break for not ...
If it is, we set the value of index to the current index and break out of the loop using the break keyword.If the search element is not found in the list, the value of index remains None, since we initialize it to None before the loop....
By default, the sorted() function sorts items in ascending order. If you need to sort the items in descending order, then you can use the reverse keyword-only argument. If you set reverse to True, then you get the data in descending order:...
Pyppeteer functions accept both dictionary and keyword arguments for options Example: browser = await launch({'headless': True}) browser = await launch(headless=True) Puppeteer JavaScript uses the $ for the element selector. However, in Python, $ is not a valid identifier, instead of $ python...

Introduction to Python Lambda Functions Lambda functions in Python are small, anonymous functions defined with the 'lambda' keyword. They are useful for creating simple functions without needing to formally define a function using 'def'. This tutorial will guide you through various examples of using...
