IntroductionIn this program, you will be taught how to use if, elseif and else conditional statements in Python. if/else/elseif syntax in Python:if (expression): Statement(s) elif (expression): Statement(s) else: Statement(s) As you may have noticed, Python uses elif in place of elseif in Java. Also, Python is a little picky about indentation; hence it is recommended that you use the if, elif and else syntax as shown above. Problem:Write a Python program that displays the days in a month. |
|---|
Step 1: Get input(s) needed to solve the problem.
You will need the following in order to solve this problem.
Step 2: Write the program.
#############################################################
#This program is used to display the number of days in a month
## Get input from the user
month = input("Please enter a month in number format (1-12): ")
#Display the appropriate number of days contained in the selected months
#If the month is invalid, display appropriate message
if(month == 1 or month == 3 or month == 5 or month == 7 or month == 8 or month == 8 or month == 10 or month == 12):
print "This month has 31 days."
elif( month == 4 or month == 6 or month == 9 or month == 11 ): #Months that have 30 days
print "This month has 30 days."
elif( month == 2 ): #February has 28 days
print "This month has 28 days."
else: #Not a valid month
print "Invalid Month."
Step 4: Contrast with Days in a month program in Program a Day
This Python program performs exactly the same function as the Java WindChill program in Program a Day.
