What is == in Python?

What is the difference between if else and if Elif else statement?
The elif is short for else if. It allows us to check for multiple expressions. If the condition for if is False , it checks the condition of the next elif block and so on. If all the conditions are False , the body of else is executed.
What is the difference between if and if else statement?
The if statement is a decision-making structure that consists of an expression followed by one or more statements. The if else is a decision-making structure in which the if statement can be followed by an optional else statement that executes when the expression is false.
Can you have multiple IF statements in Python?
Nested if statements means an if statement inside another if statement. Yes, Python allows us to nest if statements within if statements. i.e, we can place an if statement inside another if statement. Here, a user can decide among multiple options.
How can multiple conditions be checked in if else?
To test multiple conditions in an if or elif clause we use so-called logical operators. These operators combine several true/false values into a final True or False outcome (Sweigart, 2015). That outcome says how our conditions combine, and that determines whether our if statement runs or not.
How many conditions are checked in single if/then else statement?
Technically, the `if`statement support only one condition, and it will evaluate that condition to a boolean value – either `true` or `false`.
Can IF statement have 2 conditions?
We can either use one condition or multiple conditions, but the result should always be a boolean. When using multiple conditions, we use the logical AND && and logical OR || operators. Note: Logical AND && returns true if both statements are true. Logical OR || returns true if any one of the statements is true.
Can you use multiple Elif statements?
The elif statement also takes an expression which is checked after the first if statement. You may use multiple elif statements.
How many conditions are checked in if Elif else type statement?
There can be multiple ‘elif’ blocks, however there is only ‘else’ block is allowed. 2. Out of all these blocks only one block_of_code gets executed.

What is the IF ELSE statement?
The if/else statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.
Can you use else if in python?
An else statement can be combined with an if statement. An else statement contains the block of code that executes if the conditional expression in the if statement resolves to 0 or a FALSE value. The else statement is an optional statement and there could be at most only one else statement following if.
