Definition of Python 3 else if
Python 3 else if statement comprises a block of code that executes. If we combine an else statement with an if statement. The statement of else is optional, and there can only be one after if. When we wish to run a program only if a specific condition is met, we need to make a decision. Python makes decisions using the if elif else statement.
What is python 3 else if?
- In real life, there is a situation where we are required to complete a given task and must select what to do next based on a set of circumstances. In programming, there are times when a task must be completed only if a certain condition is true.
- Else if statements can help in certain situations. The conditional statements are provided by python.
- If the statement is true, then if the statement is executing the statement of block; if the stmt is false, then if statement will not execute a set of statements.
- The code of block is incorporated as an else statement in a conditional if statement, which is executed when the if statement is false.
- Below is the syntax of python 3 else if statements are as follows.
If (condition) # Block of statement Else (condition) # Block of statement.
- If loop condition was true, then else if the statement analyses the test expression and executes the body of the if statement.
- If suppose loop condition was false, then otherwise the body is run. The blocks are separated using indentation.
- The test expression must first be verified. The body of the if statement is executed if the expression returns true. If it’s false, the statement will be executed following the if statement.
- Below is the flowchart of else if statement in python is as follows.
- When compared to a simple if statement, else if will add extra stage to the decision-making process.
- Starting of the else if stmt. is similar to that of a basic if statement; but, if the condition is false, the indented phrase will be printed instead of nothing.
- The statement itself specifies that if a particular condition is true, then the statements inside the “if block” should be executed, after giving a false statement, the “else” block should be executed.
- If the condition is false will the “else” block be executed? The Boolean expression is evaluated using the if-else statement. When a statement is true, the “if” block’s code will be executed.
Python 3 else if conditionally
- In below, examples find the absolute value of the supplied integer py. If py > 0, the software should display the value py; otherwise, it should display the value -py.
- The sequential program is unable to achieve this behavior. The program should choose the next step based on the conditions.
py = int (input()) if py > 0: print (py) else: print (-py)
- It is used in this program as a conditional statement. We added a condition of py > 0 after the if, followed by a colon. Then we add a block of instructions that will only run if the stmt is true.
- This block may be followed by the word else, a colon, and a new set of instructions that will only be performed if the stmt is false.
- Because the stmt is false in the example above, the ‘else’ block is run. Spaces should be used to indent each block.
- Any Python instruction, including another conditional statement, can be placed in the ‘true’ and ‘false’ blocks. Inner condition blocks have twice as many spaces indented.
- The below example shows how python 3 else if statement is working, are as follows.
py1 = 15 py2 = 25 if py1 > 35: if py2 > 65: print ("Stmt 1") else: print ("Stmt 4") else: if py2 > 30: print ("Stmt 2") else: print ("Stmt 3")
- We have declared two variable names as py1 and py2 also we have assigned 15 and 25 values respectively to them.
- In the above example, we have declared two variables and assigned values to them. In the first expression, we have given false conditions so the loop will go in the second else condition to execute the condition.
- After going into the second condition we have given a false condition in the first if block, so it will execute the last block of else statement. It will be printing the “stmt 3”.
Python 3 else if statement
- If statement is true, the If statement in Python instructs the program what to do. In the event that statement is false, the program simply executes the statements following the if statements.
- The below example shows python else if statements are as follows.
py = 15 if (py == 5): print ("py is 5") elif (py == 25): print ("py is 25") elif (py == 15): print ("py is 15") else : print ("not found")
- In the above example, we have declared a variable as py and assigned 15 values to this variable. Also, we have used the else if statement in the else if statement we have used elif statement two times.
- After becomes a true condition of the statement the output is showing as “py is 15” because we have assigned a value of py variable is 15.
- The below example shows else if statements with the preceding conditions are as follows. We have declared two-variable names as py1 and py2 and assigned 15, 25 values to them.
- After declaring the value the condition statement is checking the true condition in the first if statement. Then it will executing a true statement block.
py1 = 15 py2 = 25 if py2 > py1: print ("Py2 is greater") elif py1 == py2: print ("py1 and py2 values are same") else: print ("Py1 is greater")
If statement is true, then if statement is executing the statement of block; if the condition is false, then if statement will not execute a set of statements. Python 3 else if statement comprises a block of code that executes. If we combine an else statement with an if statement.
