The len() method in Python
Python len() method can be used for getting the length of a given string, sequence and collection.
Python len() Function
The Python has a built-in method len() for getting the total number of items in a list. The len() method takes an argument where you may provide a list and it returns the length of given list.
Python input vs raw_input function
The Python 3 input function enables us to take the user input from the keyboard. As a line of code containing the input function executes, the user will be prompted to enter the required information.
Python sqrt(x) Function to Calculate Square Root
The sqrt(x) function is used to get the square root of the given number in Python. The sqrt() function is the part of math module so you need to import it before using in Python program.
Filter Function in Python
The filter function is used to build an iterator (a list, tuple etc.) after taking an iterable and a function as parameters. The built iterator contains only those items that returned as true after passing to function.
Python Lambda Function
The nameless or anonymous function can be created by using the keyword lambda. These are small functions that you may use when function objects are required.
Python map() Function?
The Python map() function is used to apply a function (custom or built-in) to each item of one or more iterables (lists, tuples, set etc.). The map returns iterable e.g. a list after applying the given function – yielding the result.
