work with it, and then give you a result using the “return” statement. Functions are handy because they help organize the code into smaller and logical parts, making it easier to read and maintain. You can use afunction in Pythonover and over with different...
Python type() is a built-in function that helps you find the class type of the variable given as input.You have to just place the variable name inside the type() function, and python returns the datatype. Mostly, We use it for debugging purposes. we can also pass three arguments to ...
In this tutorial, we take you through how to use the print() function in the Python programming language.
You can display a function to the console with print(), include it as an element in a composite data object like a list, or even use it as a dictionary key:Python >>> def func(): ... print("I am function func()!") ... >>> print("cat", func, 42) cat <function func ...
However, in real-world programs, we use the return keyword to return back the result of the function. The return keyword allows us to store the result of the function in a variable. Unlike many other languages, we do not need to declare a return type of the function explicitly. Python ...

Both eval and exec methods allow you to process and execute Python code chunks. You can supply eval statements to other Python functions as arguments as they always return a value, somewhat similar to lambda functions in Python. Similarly, you can use the exec function to execute predefined Pyt...
A Python generator is a type of function that allows us to process large amounts of data quickly and efficiently. They are generally thought of as a complex concept in Python. That's why they are consistently seen on job interviews. Generators aren't just an arcane bit of programming used...
