If else statements in freemat12/8/2022 ![]() ![]() Let’s get more clarity on the ‘if-else statement’ with some examples and flowcharts. To achieve this we have to follow the indentation of Python. Any number of if statements can be nested inside each other. We can have an if statement present inside another if statement. What if we want to check a condition only if it has passed a previous condition? IF ELSE STATEMENTS IN FREEMAT CODENote: In the above code snippet, the last print statement will get printed and does not depend on the condition, as it is out of the if-else block(unintended). In this example, -5 being a negative number makes the condition True so executes the if block. If it turns out to be True then the program will run the if block & if it turns out to be False it runs the else block. We check if it’s Positive or Negative by the condition num < 0. Here we take a number as input from the user. Print ( "This is outside the if-else statement block" ) Print ( "The number you have entered is Positive" ) Print ( "The number you have entered is Negative" ) The ‘if statement’ uses the if keyword followed by the condition which needs to be checked. ![]() Let’s get more clarity on the ‘if statement’ with some examples and flowcharts. The condition could be any sort of logical expression which can give either True or False after evaluation. This is used to run a block of code only if the condition given in the ‘if statement’, comes out to be True. This allows you to make use of much more complicated logic. One of the most simple decision-making statements in Python is the ‘if statement’. The if and else statements take a script block, so we can place any PowerShell command inside them, including another if statement. In this article, we are going to learn some of the conditional statements in Python programming with some examples. The decision-making statements are the most important aspect of a programming language as it decides the flow of the program execution. Condition checking forms the backbone for decision-making during programming. Such similar decision-making situations are required during programming, such as to execute a particular block of code only when only certain specific conditions are satisfied. These operators are used to write the expression of the condition.Every other day in your life you have to make some decisions right? Based on those decisions we come up with our next step. Along with the syntax of the conditional statement, you should also know the relational operators. These are the flow control statement which directs the execution by evaluating the condition. Let’s see how ‘switch-case’ can be used in the above-given example?Įxample: Figure 04: Flow control using ‘switch-case’ statement In ‘if-else’, you need to write multiple ‘if-else’ statements and expression based on the condition but in ‘switch-case’ you need to write only one expression for the multiple cases. ‘switch-case’ also has a default statement in case of failure of any matches with the given cases. ![]() Based on the value of the parameter, a particular case is executed. The last ‘else’ contains the default statement.Įxample: Figure 03: Flow control using if-(else-if….)-else conditionĪnother type of flow control statement which saves you to write multiple else-if statements when you have a large number of cases. If you have multiple conditions then use else-if to evaluate those conditions and execute the respective statements. The curly-brace will start just after ‘else’ word.Įxample: Figure 02: Flow Control using ‘if-else’ condition On the other hand, if you have more than one statements then enclose them in a curly-brace. If there is only one line statement then you can write just after the ‘else’. The ‘else’ part contains the default statements. If the condition of the first part does not fulfil then the statements written in the second part will execute automatically. In case of failure of condition, the next statement or statements enclosed by curly braces are skipped and continue the execution.Įxample: Figure 01: Flow Control using ‘if’ condition If the condition is fulfiled then only the next statement or statements enclosed by curly braces are executed. It evaluates the value of a variable against the given condition and controls the flow as per the output (True or False). For that purpose, you need to tweak the code. The conditional statement evaluates the given condition and controls the flow of the script.Īlong with flow control task, LoadRunner ‘if’ statement also helps to check the correctness of response and marks a transaction Pass or Fail. ‘if’ is a conditional statement in LoadRunner and its syntax is as same as C language conditional statement. ![]()
