Comparison operators are used to compare two values. They evaluate expressions and return a Boolean result: either True or False. These operators are especially useful in conditions and loops.
Python provides six main comparison operators: ==, !=, >, <, >=, and <=.
Example 1: Equal To (==)
a = 10
b = 10
print(a == b)Returns True because both values are equal.
Example 2: Not Equal To (!=)
name1 = "Alice"
name2 = "Bob"
print(name1 != name2)Returns True since the strings are different.
Example 3: Greater Than (>)
marks = 85
print(marks > 75)Returns True if the first value is greater than the second.
Example 4: Less Than (<)
x = 5
y = 10
print(x < y)Returns True because 5 is less than 10.
Example 5: Greater Than or Equal To (>=)
score = 90
print(score >= 90)This returns True because the value is equal to 90.
Example 6: Less Than or Equal To (<=)
age = 17
print(age <= 18)Returns True since 17 is less than 18.
Example 7: Comparison in if Statement
temperature = 38
if temperature > 37:
print("Fever detected")Comparison operators are often used in if statements to control flow.
Example 8: Comparing Strings
word1 = "apple"
word2 = "banana"
print(word1 < word2)Strings are compared based on their Unicode order. Returns True.
Example 9: Comparing Lists
list1 = [1, 2, 3]
list2 = [1, 2, 4]
print(list1 < list2)Lists are compared element by element. Returns True because 3 is less than 4.
Example 10: Boolean Result of Comparison
result = 100 == (50 * 2)
print(result)Comparison expressions return Boolean values which can be stored in variables or used in logic.
Summary
==checks if values are equal!=checks if values are not equal>checks if the first value is greater<checks if the first value is smaller>=checks if the first value is greater or equal<=checks if the first value is smaller or equal
Understanding comparison operators is essential for writing effective conditions, filtering data, and building logic in Python programs.
