What is an indent in python?
Indentation refers to the spaces at the beginning of a code line. Python uses indentation to indicate a block of code.
What is type casting with example in python?

Casting in python is therefore done using constructor functions: int() – constructs an integer number from an integer literal, a float literal (by removing all decimals), or a string literal (providing the string represents a whole number)
What is type casting with an example?
It is used in computer programming to ensure a function handles the variables correctly. A typecast example is the transformation of an integer into a string. This could be used to compare two numbers if one is stored as a string and the other is an integer.
Why is casting important in Python?
Python avoids the loss of data in Implicit Type Conversion. Explicit Type Conversion is also called Type Casting, the data types of objects are converted using predefined functions by the user. In Type Casting, loss of data may occur as we enforce the object to a specific data type.
How do you indent in Python?
Select the lines to indent. Click and drag with your mouse to select the code (the last print statement), or press Shift while using your arrow keys. Choose Format → Indent Region. Ctrl+] also works.
What is casting in programming?
Casting means changing the data type of a piece of data from one type to another. The data may be stored inside a variable. To be able to perform calculations with a number, it needs to have a numeric data type — either integer or real number.
How do you cast an int in Python?
To convert a string to integer in Python, use the int() function. This function takes two parameters: the initial string and the optional base to represent the data. Use the syntax print(int(“STR”)) to return the str as an int , or integer.
How do you cast an object in Python?
There is no “casting” in Python. Any subclass of a class is considered an instance of its parents. Desired behavior can be achieved by proper calling the superclass methods, and by overriding class attributes.
