python Ternary operator

Posted by: instanceofjava Posted date: June 26, 2021 / comment : 0

Ternary operator: 

  • The ternary operator is defined as the operator that evaluates the conditions to find the final result.
  • It evaluates more than one expression.
  • A  single line code is written according to the condition.
syntax:  x= first value if condition else second value.
In this syntax, if the first value satisfies the condition then it returns the x value, if the first value doesn't satisfy the condition then it goes to the else part and checks the second condition.

Example: x=20 if 5<10 else 30 we get the result as 20.
Because here condition 5<10 is grue so it returns the x value as 10.

  • There is another syntax for the ternary operator when there are more than 2 conditions i.e;
  • syntax: x= first value if condition 1 else second value if condition 2 else third value.
Example: x=1 if 20>30 else 2 if 50>60 else  10. 
                The result is  10.
  • In the ternary operator, we can perform a nested loop also.
  • We can reduce the length of the code by using this ternary operator, in this operator we write a code in a single line.
  • So time is saved and less complexity in the code.

#write a python program for integers using the ternary operator.

  1. a=8
  2. b=9
  3. max= b if b>a else a.
  4. print(max)
output: 9



python not operator

 Python not operator:

  • python not operator is the complement of the given value i.e; if the value is true then it returns false and if the value is false then it returns true.
  • When we  apply the not operator we get result  in  boolean type .
  • example:
                 x=10 
                 not x, then the result is false because x=10 is true so not x is false.
  • syntax:(not x).

 # write a python program using not operator.

  1. x="python"
  2. y="java''
  3. print(not x==y)
output: true

 

python and operator

 python And operator:

  • The python And operator is one of the logical operators.
  • In And operator, if both the operands are true then it returns true, otherwise false.
  • And operator is applicable for boolean type and non-boolean type.
  • For example: 1 And  " a"  then the result is "a".  
  •  It is represented by the  "&" symbol.
  •  It is written as  x &y
syntax:(a&b).

# write a python program using And operator.

  1. x=23
  2. y=44
  3. print(x>10 and y>10)
  4. print(x<40 and y<40)
  5. print(x&y)
  output:   true
                false
                 4

Types of operators in python

Posted by: instanceofjava Posted date: June 25, 2021 / comment : 0

 Operators: 

  • Operators are nothing but the special symbols used in between the operands.
  • In python, we use the operators to perform some arithmetic, logic, and some more operations.
  • These operations are performed on the variables, values, arguments nothing but the operands.
  • We can perform operations on one or more operands.
  • In python, we have six operators.
  • Arithmetic( to add),comparison(to compare), logical( perform logical operations), bitwise(cal bitwise operations), assignment(assign values), special(check address and content ).

1.Arithmetic operator:

  • It is also called a math operator and it applicable for all int and float types values.
write a python program using the math operators/arithmetic operators.



2. comparison operator:

  • It compares and shows the relation of variables.
write a python code using comparison operators.




3. Logical operator: 

  •  This operator performs the logical operations on variables.
  • There are 3 logical operators.
write a python program using logical operators.



4. Bitwise operator:

  • It is used to perform bit-wise calculations.
  • We have 6 operators and applied to int and bool.
write a python code using bitwise operators.



5. Assignment operator:

  • It assigns the values to variables.
  • we have 12 operators in it.
write a python program using the assignment operators.



6.Special operator:

  • In, not in and is, is not are special operators.
  • Membership operators and identity operators are 2 types in it.
  • Membership operator is used to giving member is present in the list or not.
  • eg: list=[1,2,3]
  • pint(1 is a list )
  • output: true.
write a python program using the special operator.



python math operators

Math operators:

  • In python, we have various arithmetic operators.
  • These are called math operators because they perform different types of mathematical operations.
  • Here  we have seven types of arithmetic operators:
  1. +     addition
  2. -      subtraction.
  3. /       division.
  4. %     modulus.
  5. *       multiplication.
  6. //       floor division.
  7. **      exponential.
1.Addition(+): It is used to add two or more operands.
It is represented by the "+". symbol.
syntax:(a+b).

2.subtraction(-): It subtracts the value of the  one operand to other operands 
It is represented by the symbol "-".
syntax:(a-b).

3.Division(/): It divides one operand with another operand and gives the remainder. The result is always in float type only.
It is represented by the symbol "/'.
syntax:(a/b).

4.modulus(%): It is the remainder of the operands.
It is represented by the symbol "%".
syntax:(a%b).

5.Multiplication(*): It multiply the two or more operands.
It is represented by the symbol "*".
syntax:(a*b).

6.floor division(//): It divides the operands and get the result in the whole number only.
It is represented by the symbol "//'.
syntax:(a//b).

7.exponential(**): It is used to calculate the power of the values.
It is represented by the symbol "**'.
syntax:(a**b).


Example: write a python program for integers using math operators.

  1. x=3
  2. y=4
  3. print(x+y)
  4. print(x-y)
  5. print(x/y)
  6. print(x%y)
  7. print(x*y)
  8. print(x//y)
  9. print(x**y)
output:     7
               -1
               0.75
                3
               12
               0
               81




python division operator

Posted by: instanceofjava Posted date: June 25, 2021 / comment : 0

  • The division operator in python is used to perform the division operations.
  • It divides the left-side values with the right-side value and gives the remainder.
  • In other languages, we have only one division operator but in python, we have 2 division operators.
  1. division.
  2. floor division
 1.Division: In division when we divide values we get the result in floating type.
It is denoted by the symbol "/".
 syntax:(x/y).

Example: write a python code for integers using a division operator.

  1. x=20
  2. y=4
  3. print(x/y)
output:5.0



2.floor division(//):  In the floor division when we divide the values we get the whole number only.
It is denoted by the symbol "//".
syntax:(x//y).

Example: write a python program for integer values using floor division.

  1. x=20
  2. y=4
  3. print(x//y)
output: 5















Python modulo operator

Posted by: instanceofjava Posted date: June 25, 2021 / comment : 0


In Python, the modulo operator is represented by the percent sign (%). It is used to find the remainder of a division operation between two numbers. 
Here's an example of  modulo operator In Python

x = 7
y = 3
remainder = x % y
print(remainder)

This will print 1 as the remainder of 7 divided by 3 is 1.
modulo operator to check if a number is even or odd:


x = 7
if x % 2 == 0:
    print(x, "is even")
else:
    print(x, "is odd")
This will print "7 is odd" because the remainder of 7 divided by 2 is 1.

The modulo operator can also be used to wrap around a range of values. For example, you can use it to ensure that an index is always within the bounds of an array, even if the index is negative or greater than the size of the array:


index = -1
size = 5
correct_index = index % size
print(correct_index)

This will print 4 as the correct index, because -1 % 5 = -1, but we want the index to be between 0 and 4.

It's worth noting that, the modulo operation is defined as the remainder of the division of one number by another, i.e x % y = x - y * floor(x/y)
where floor is the floor division operator, that returns the quotient of the division and also discards any remainder.

  • Modulo operator:  The modulo is defined as "the remainder of the two arguments ".
  • It is denoted by the symbol   "%".
  • When we divide any number with 0 i.e;    x%0 the result is zero division error.
  • We can use int, float, and double values also.
  • Those int, float, double may be either positive or negative.
syntax:(x%y)
x is the first argument and y is the second argument.

#1.write a python program using the modulo operator.

  1. x=10.0
  2. y=2.0
  3. print(x%y)
output: 0.0


#2.write a python program for a value divides with 0 using the modulo operator.
  1. x=10.0
  2. y=0
  3. print(x%y)
output: zero division error
