- 2. AGENDA • SIMPLE IF ELSE STATEMENT • CONDITIONAL TESTS • AND, OR OPERATOR • ADVANCED IF ELSE STATEMENTS
- 3. EXAMPLE • Example 1 • number = 2 • If number is odd, print “odd number” • If number is even, print “even number” • Example 2 • name = ‘Shivam’ • If name is ‘Shivam’, print it in capital letters • Otherwise, print as it is
- 5. • Conditional test • If test is true, execute the code under if statement • If test is false, ignore the code under if statement and move forward
- 7. • Equality operator returns True if value on left and right side matches. Otherwise, False. • Assignment operator(=) vs Equality operator(==) • Assignment -> Storing a value in a variable • Equality operator -> Are the values equal on both the sides ?

- 13. CHECKING MULTIPLE CONDITIONS • you might need two conditions to be True to take an action • you might be satisfied with just one condition being True • Keywords – and, or
- 14. USING AND TO CHECK MULTIPLE CONDITIONS • Multiple tests • If all test passes, return True • If even one of the test fails, return False • Checking happens in order • If one test returns False, further checking doesn’t happen
- 15. • More than 2 tests are also possible
- 18. USING OR TO CHECK MULTIPLE CONDITIONS • Multiple tests • If any one of the test passes, return True • Go in order and stop when any test passes • If all the test fails, return False

- 22. CHECKING WHETHER A VALUE IS NOT IN THE LIST
- 23. BOOLEAN EXPRESSIONS • Another name for conditional statements • A Boolean value is either True or False
- 24. IF STATEMENTS
- 32. GRADING • marks >= 90 and marks <= 100 – A • marks >= 70 and marks < 90 – B • marks >= 50 and marks < 70 – C • marks >= 40 and marks < 50 – D • Otherwise, F
- 34. OMITTING THE ELSE BLOCK
- 36. USING IF STATEMENTS WITH LISTS • ODD EVEN EXAMPLE • SEARCH A NAME EXAMPLE
- 37. CHECKING IF A LIST IS EMPTY
- 38. ASSIGNMENT a = 2 b = 3 If a is greater than b, print “a > b” If a is smaller than b, print “a < b” If a is equal to b , print “a = b” Note: a and b can take any values
- 39. WRITE SOME BASIC PROGRAMS IN PYTHON
