Explanation of output: 3 is starting value, 8 is stop value and 2 is step value. The while loops control condition is carried out before any statements inside the loop are performed. Out of loop), Output:Num has value 1Num has value 2Num has value 3Num has value 4Num has value 5Num has value 6Num has value 7Encountered break!! Write a program to calculate the factorial of a given number. Write a program to find the sum of 1+ 1/8 + 1/271/n3, where n is the number input by the user.Answer sum = 0n = int(input(Enter the number: ))for a in range(1,n+1):sum = sum + (1/pow(a,3))print(The sum of series is: ,round(sum,2)), Output Enter the number: 10The sum of series is: 1.2, 7. In above example you can see that the program is dependent on the boolean_expression, If the for example the following loop will print A infinite times. Conditions are tested by selection statements, This type of statement depending on the condition and generate the result based on condition. Control flow structure . example do-while. #Program to create a four function calculatorresult = 0val1 = float(input(Enter value 1: ))val2 = float(input(Enter value 2: ))op = input(Enter any one of the operator (+,-,*,/): )if op == +: result = val1 + val2elif op == -: if val1 > val2: result = val1 val2 else: result = val2 val1elif op == *: result = val1 * val2elif op == /: if val2 == 0: print(Error! The range() is a built-in function in Python. The certification names are the trademarks of their respective owners. My CS Tutorial is the best place for study free by experts.

Flow of Control in Python Class 11 Notes Indentation The statements included within a block are typically enclosed in curly brackets in programming languages. 3. An infinite loop continues to repeat until the program is interrupted. Save my name, email, and website in this browser for the next time I comment. continue statement is used to skip the current iteration of the loop and pass the control to the next iteration. 9. Write a function to print the table of a given number. I am a teacher with more than 17 years of experience in education field. So, a loop that never ends is known as an infinite loop.Example i = -1while(i != 1):print(1)i -= 1, 5. It shows steps in a sequential order, and is widely used in presenting flow of algorithms, workflow or processes. Python does not impose any restriction on how many loops can be nested inside a loop or on the levels of nesting. 4.5 Nested Loop :A loop inside another loop is known as nested loop.Syntax:for in :for in :statement(s)statement(s)Example:for i in range(1,4):for j in range(1,i):print(*, end= )print( ), Programs related to Conditional, looping and jumping statements, Table Joins And Indexes In Sql Class 11 Computer Science Important Questions, MCQ Questions For Class 10 Information Technology Chapter 1 Communication Skills-II, Redox Reactions Class 11 Chemistry Notes and Questions, Desktop Publishing Class 11 Computer Science Notes and Questions, Class 11 Business Studies Notes And Questions, Class 12 VBQs Biology Microbes in Human Welfare, MCQ Question For Class 12 Informatics Practices Chapter 3 Data Handling Using Pandas II, Class 12 Informatics Practices Sample Paper Term 1 With Solutions Set B, Class 12 Computer Science Sample Paper Term 1 With Solutions Set C, Class 12 Informatics Practices Sample Paper Term 1 With Solutions Set A, returns the generator object that can be used to display numbers only by looping, The variable storing the range takes more memory, variable storing the range takes less memory, all the operations that can be applied on the list can be used on it, operations associated to list cannot be applied on it. Q. Q. As soon as the user enters a neagtive number, stop taking in any further input from the user and display the sum . A statement or set of statements that is repeated as long as the condition is true. Q. These statements are provided by Python as a tool to provide the programmer additional control over how a programme is executed. Q11. The short version of an if/else. Teachers and Examiners (CBSESkillEduction) collaborated to create the Flow of Control in Python Class 11 Notes. What is the purpose of range() function? Write a program to create a simple calculator performing only four basic operations. In order to control the flow of a program, we have conditional programming and looping. stopping, it is called an infinite loop. write a count-controlled loop. When a specific condition is met, there are times when we may want to end a loop (coming out of the loop indefinitely) or skip a few of its statements before proceeding. It evaluates an expression and, based on the result, choose which part of the code to execute Program to print the characters in the string PYTHON using for loop. If the if condition is False, the next elif blocks condition is checked, and so on. example of selection statement is IfElse statement and Switch Statement. Program terminated) else: result = val1/val2else: print(Wrong input,program terminated) print(The result is ,result), Output:Enter value 1: 84Enter value 2: 4Enter any one of the operator (+,-,*,/): /The result is 21.0. Write a function to print the table of a given number. Give one example.Answer The test condition for the loop must finally become false according to the statement contained in the body of the loop; otherwise, the loop will continue indefinitely. Output 1: Enter the number to be checked: 20 20 is not a prime numberOutput 2: Enter the number to check: 19 19 is a prime numberOutput 3: Enter the number to check: 2 2 is a prime numberOutput 4: Enter the number to check: 1 Entered number is <= 1, execute again! Please find the below example: # This program demonstrates an infinite loop. Program to check if the input number is prime or not. Write a program to input marks in 3 subjects; compute average and then calculate grade as per following guidelines: P.I.P: - 4.2 Q8. Q. First print 3 and increase it by 2, that is 5, again increase is by 2, that is 7. Conditional Programming Python provides conditional branching with if statements and looping with while and for statements. Display the appropriate message as per the colour of signal at the road crossing. Program to print even numbers in a given sequence using for loop. #Program 6-6#Print the characters in word PYTHON using for loopfor letter in PYTHON: print(letter). The looping constructs while and for allow sections of code to be executed repeatedly under some condition.
