Ternary operator in python

The ternary operator in python:-

It is used to solve a condition-based program using a single-line statement. ternary operator contains an if-else statement using a single line.

It is used to solve a condition-based program using a single-line statement.

Syntax:-

var =  True statement if condition else false statement

print(var if condition else var)

Example of a ternary operator in Python?

Q) WAP to check the greater number using Ternary Operator?

Solution First:-

a = int(input("enter first number"))

b = int(input("enter second number"))

res =  "a is greater" if a>b else "b is greater"

print(res)

Solution Second:-

a = int(input("enter first number"))
b = int(input("enter second number"))
print(a if a>b else b)

WAP to check vowel and consonant using a ternary operator?

s = input("enter char to check vowel and consonent")

o = "Vowel" if s=='a' or s=='e' or s=='i' or s=='o' or s=='u' else "Consonent"

print(o)

Nested Ternary:-

We can create more than one Ternary Statement using a nested sequence.

var =  (True if condition else false) if condition else (True if condition else false)

 

Example of Nested ternary:-

WAP to calculate the greatest number using a ternary operator in Python?

a = int(input("enter first number"))

b = int(input("enter second number"))

c = int(input("enter third number"))

res =   "a is greatest" if a>c else "c is greatest" if a>b  else "b is greatest" if b>c else "c is greatest"

print(res)

Advantage:-

Its performance is better if we can solve expression using a single line

Disadvantage:-

It is not used to solve complex condition-based or multiple lines based program logic.

Assignment of Ternary Operator:-

1) WAP to check leap year using a ternary operator in Python?

   

Solution:-

year  = int(input("enter year"))

s = "Leap year" if(year%400==0 or (year%4==0)  and  (year%100!=0) ) else "NOT Leap year"

print(s)

2)  WAP to check divisibility of number that it is divisible by 3 and 5 or not?

Solution:-

num = int(input("enter number"))

s = "divisible" if num%3==0 and num%5==0 else "not divisible"

print(s)

3)  WAP to check divisibility of a number by 3 and 5, individually and both?

num = int(input("enter number"))

s = "divisible by 3 and 5" if num%3==0 and num%5==0 else "divisible by 3" if num%3==0 else "diviblle by 5 " if num%5==0 else "not divisble by 3 and 5"

print(s)

4)  WAP to check that salary is in income tax or not display the total amount and the taxable amount 

sal = int(input("enter salary"))

s = "not taxable" if sal<=250000 else "Tax amount is " + str(sal-250000)

print(s)

5)  WAP to calculate electricity bill where unit price, total consumption will be entered by the user, if the bill is <400 then pay only 100 RS and above this 50% amount will be paid.

Solution:-

up = float(input("enter unit price"))

con = float(input("enter consumption"))

total = up*con

s = "pay only 100 rs " if total<400 else  "Actual bill is " + str(total) + "payble bill is " + str(total/2)

print(s)
