What is the code behind an if statement?
To write an if statement, write the keyword if , then inside parentheses () insert a boolean value, and then in curly brackets {} write the code that should only execute when that value is true . That code is called the body of the if statement.
What does ELSE IF statement represent in coding?
In programming languages, an else statement is an alternative statement that is executed if the result of a previous test condition evaluates to false.
What is then in Python?
Python does not use the word THEN but uses a colon instead. We will look at the following different ways: Using a user-defined function. Using a lambda function.
Can IF statement have 3 conditions?
If you have to write an IF statement with 3 outcomes, then you only need to use one nested IF function. The first IF statement will handle the first outcome, while the second one will return the second and the third possible outcomes. Note: If you have Office 365 installed, then you can also use the new IFS function.
What does != Mean in code?
not-equal-to operator
The not-equal-to operator ( != ) returns true if the operands don’t have the same value; otherwise, it returns false .
What does Elif mean in coding?

The elif keyword is used in conditional statements (if statements), and is short for else if.
What is the difference between if and if else statement?
– If support statements for true part only – If-else support statements for true and false – If the test expression is true then a true block statement is executed otherwise – Either the true block statement or false block statement is executed every time
What does IF ELSE statements mean?
If else. An if else statement in programming is a conditional statement that runs a different set of statements depending on whether an expression is true or false. A typical if else statement would appear similar to the one below (this example is JavaScript, and would be very similar in other C-style languages).
What are the advantages of IF ELSE statements?
– Easier to debug (e.g. – Easier to read (subjectively) – Easier to understand, and therefore – Easier to maintain – Fixed depth: a sequence of “if else if” statements yields deep nesting, making compilation more difficult (especially in automatically generated code) – Faster execution potential – Easier to study and write the examination for students
What is the difference between IF ELSE if and switch statement?
Key Differences Between if-else and switch The expression inside if statement decides whether to execute the statements inside if block or under else block. You can have multiple if statement for multiple choice of statements. If-else statement checks for equality as well as for logical expression. The if statement evaluates integer, character, pointer or floating-point type or boolean type.
