Conditional statements allow a Python program to make decisions. Instead of running every line of code in the same way, a program can choose what to do based on conditions. This is what makes software intelligent rather than mechanical.
In Python, conditions are written using keywords like if, elif, and else. These statements check whether a certain condition is true or false and then execute the appropriate block of code. For example, a program can check whether a user is logged in, whether a number is greater than another, or whether input is valid.
Without conditional statements, programs would always behave the same way no matter what data they receive. With conditions, a program can respond differently to different situations. This is how login systems, game logic, pricing rules, and decision-making systems are built.
In short, conditional statements are the brain of a program. They allow Python to analyze information and choose the correct action.Conditional statements allow a Python program to make decisions. Instead of running every line of code blindly, a program can look at a condition and choose what to do. This is what separates real software from a simple calculator.
Conditions
A condition is something that can be either True or False.
Examples of comparison operators:
>greater than<less than==equal to!=not equal to>=greater or equal<=less or equal
Example:
age = 20
if age >= 18:
print("You can vote")Here, >= is a comparison operator. It checks whether age is greater than or equal to 18.
Real-Life Examples
Think about a Voting.
If your age is 18 or more, you can vote.
Otherwise, you cannot.
This is exactly how a conditional statement works:
if age >= 18:
print("Allowed")
else:
print("Not allowed")Another example is an exam result.
If marks are greater than or equal to 40, you pass.
Otherwise, you fail.
if marks >= 40:
print("Pass")
else:
print("Fail")In both cases, the program is not guessing. It is comparing values using operators and then choosing an action.
Why Conditional Statements Matter
Every real system depends on conditions:
- Login systems check if the password is correct
- Shopping apps check if money is enough
- Games check if health is zero
- Websites check if a user is authorized
Without conditional statements, none of this would work.
They are the logic engine of a program.In short, conditional statements are the brain of a program. They allow Python to analyze information and choose the correct action.
