How to Use If/else/elif Statement in Python !

if condition:

The if condition is considered the simplest of the three and makes a decision based on whether the condition is true or not. If the condition is true, it prints out the indented expression. If the condition is false, it skips printing the indented expression.

Example:-

x = 5
if x / 5 == 1:
  print("True")

OUTPUT:-

if OUTPUT is not TRUE then No Expression Show in display

if-else condition:

The if-else condition Show one by one Expression in OUTPUT.  adds an additional step in the decision-making process compared to the simple if statement. The beginning of an if-else statement operates similar to a simple if statement; however, if the condition is false, instead of printing nothing, the indented expression under else will be printed.

Example:-

x = 4
if x / 5 == 1:
  print("True")
else:
  print("False")

OUTPUT:-

if OUTPUT is  TRUE then print True Expression Show in display

if-elif-else condition:

The Most Uses and Complex of these condition is if-else-elif statement.When you run into a situation where you have several conditions, you can place as many elif conditions as necessary between the if condition and the else condition.Use the elif condition is used to include multiple conditional expressions after the if condition or between the if and else conditions.

Example:-

x = 5
 if x / 4 == 1:
   print("True")
 elif x == 5:
   print("x is equal to 5")
 else:
   print("False")

OUTPUT:-

Now, Make a Program with using if/elif/else statement:-

print("Welcome to the India Army!")

height = int(input("what is your height in cm? "))

if height >= 165:
  print("you can Join Indian army ?")
  age = int(input("what is your age? "))
  if age >= 18 and age <= 25:
    print("Please pay for Exam fees ₹ 50")
  elif age >= 26:
    print("Please pay for Exam fees ₹ 100") 
else:
  print("sorry, you have to grow taller before you can Join indian Army! ?")

OUTPUT – 1 (when height is less than requirement)

OUTPUT – 2 (when height is match with requirement and age between 18 to 25)

OUTPUT – 3 (when age greather than 25)

Thank You ! ❤️
