python comparison operators

• In python, the comparison operator is used to compare one value with the other value.
• A comparison operator can be known as a relational operator as it shows the relation between the two values.
• It returns the result in bool type i.e True or False.
• It is applicable for string, boolean, numbers(int type).
• In the comparison, if one comparison is true then the result will be true, and if one comparison is false all the results will be false.
• Eg; 10<20>30, the result is false.
• We have six different types of comparison operators/ relational operators

1. ==  Equal to.
2. != not equal to.
3. >  Greater than.
4. <   Less than.
5. >= Greater than or Equal to.
6. <= Less than or equal to.

1. Equal to(==): If the values on both sides of operands are equal then the result is true, else false.

        Equal operator(==)  always check the content comparison. 

 syntax: (a==b).

Example: write a python code for comparison/relational operator using equal to the operator for string type.

1. x='AA'
2. y='aa'
3. print(x==y)

output: false

2.     Not Equal to (!=): If both values in operands are not equal it results in true, else false.

syntax: (a!=b).

Example: write a python program using the not equal operator for an int data type.

1. x=10
2. y=20
3. if(x!=y):
4. print("x not equal to y")

output: x not equal to y.

3. Less than(<): If the value left operand is less than the right operand we use less than.

syntax: (a<b).

Example: write a python program using less than operator for string type.

1.  x="a"
2. y="A"
3. print(x<y)

output: false.

4. Greater than(>):  If the value of the left operand is greater than the right operand then the result is true. 

syntax: (a>b).

Example: write a python program for string data type using greater than the operator.

1. x="a"
2. y="A"
3. print(x>y)

output: true

5.Less than or equal to(<=): If the value in the left operand is less than or equal to right to operand it returns a true value.

syntax:(x<=y).

Example: write a python code for int data type using less than or equal to operator.

1. x=100
2. y=200
3. if(x<=y):
4. print("x less than or equal to y")

output: x less than or equal to y.

6. Greater than or equal to(>=): If the values in the left operand are greater than or equal to the right operand then the result is true else false.

syntax: (a>=b).

Example: write a python program for int data type using >= operator.

1. 1000
2. 200
3. if(x>=y):
4. print("x is greater than or equal to y")

output: x is greater than or equal to y.
