C T 01 Write a program that accepts a number from a user and outputs a message indicating whether
it is an even multiple of five. It may be easier to write the code if you recall that Python uses
logical operator to combine multiple conditions.

Program 10.2 Write a program to check whether a number is even multiple of 5.

01 # Objective: To check whether a number is even multiple of 5
02 number = int(input("Enter a number : "))
03 if number % 2 == 0 and number % 5 == 0:
04 print("Number is Even Multiple of 5")
05 else:
06 print("Number is Not Even Multiple of 5")
To combine two or more conditions, we may use logical operators. For example:
if num > 0 and num%2 == 0:
print("Positive Even Number")
If the value of num is greater than 0 and if num is divisible by 2, the conditional expression will evaluate to True.
Only then, the statement, print("Positive Even Number")will be executed.
Let us now write a program that computes a student's result based on his percentage of marks. Now we are ready
to write a function that takes two arguments, the pass percentage (passPercent) and the percentage of marks
obtained (percent) by a student, and returns his/her result.
def result(passPercent, percent):

"""
Objective: To compute a student's result
Inputs:
percent : percentage of marks
Return value:
Student's result (As str object)

"""
if percent >= passPercent:
return "Passed"
else:
return "Failed"
In the function result(), considering passPercent to be 33, if the student has scored 33 or more than 33
percent, the conditional expression percent >= passPercent will yield True, and the statement in the if
block will get executed. Thus, the function result() will return "Passed". On the contrary, if the student has
scored less than 33 percent, the conditional expression percent >= passPercent will yield False, and the
statement in the else block will be executed. So, the function result() will return "Failed".

Now, let us write a complete program that does the following four things:
1. Sets pass percentage (passPercent) as 33.
2. Accepts the student's percentage from the user.
3. Invokes the function result that accepts the pass percentage and the student's percentage of marks as
arguments and returns the student's result.

4. Prints the student's result as returned by the function result.
