COMPARISION EXPRESSION

COMPARISION EXPRESSION 

 In Python, comparison expressions are used to compare values and return a Boolean result (True or False) based on the comparison. Here are the commonly used comparison operators in Python:

1. Equal to (==): Checks if two values are equal. Example: 5 == 5 evaluates to True.

2. 
   

3. Not equal to (!=): Checks if two values are not equal. Example: 5 != 3 evaluates to True.

4. 
   

5. Greater than (>): Checks if the left operand is greater than the right operand. Example: 5 > 3 evaluates to True.

6. 
   

7. Less than (<): Checks if the left operand is less than the right operand. Example: 3 < 5 evaluates to True.

8. 
   

9. Greater than or equal to (>=): Checks if the left operand is greater than or equal to the right operand. Example: 5 >= 5 evaluates to True.

10. 
    

11. Less than or equal to (<=): Checks if the left operand is less than or equal to the right operand. Example: 3 <= 5 evaluates to True.

These comparison operators can be used with various data types, including numbers, strings, and other objects that support comparison.

Additionally, Python allows chaining of comparison operators using logical operators such as "and" and "or". For example:

x = 5 y = 10 z = 7 # Chained comparison if x < y < z: print("x is less than y and y is less than z") # Logical comparison if x > y or x > z: print("x is greater than either y or z")

In the above example, the chained comparison x < y < z checks if x is less than y and y is less than z. The logical comparison x > y or x > z checks if x is greater than either y or z.

Certainly! Here's an example code snippet that demonstrates the usage of comparison expressions in Python:

# Comparison expressions example # Numeric comparisons x = 5 y = 10 print(x == y) # False print(x != y) # True print(x > y) # False print(x < y) # True print(x >= y) # False print(x <= y) # True # String comparisons name1 = "Alice" name2 = "Bob" print(name1 == name2) # False print(name1 != name2) # True print(name1 > name2) # False (comparison based on lexicographical order)

# Chained comparison a = 3 b = 5 c = 7

print(a < b < c) # True # Logical comparison age = 25 if age >= 18 and age <= 60: print("You are eligible for work") else: print("You are not eligible for work")

In this example, we compare numeric values (x and y), string values (name1 and name2), and use chained comparisons (a < b < c) and logical comparison (age >= 18 and age <= 60) to demonstrate the usage of comparison expressions in Python.
