In Python, you can use conditional statements to make decisions based on certain conditions. This allows your programs to perform different actions or follow different paths depending on the values of variables or user input.
Comparison operators are used to compare values and determine the truth of a condition. Here are some common comparison operators in Python:
==: Equal to!=: Not equal to>: Greater than<: Less than>=: Greater than or equal to<=: Less than or equal toLet's see some examples of making decisions based on conditions in Python:
# Using if statement with comparison operators
temperature = 25
if temperature > 30:
print("It's hot outside.")
elif temperature > 20:
print("It's warm outside.")
else:
print("It's cool outside.")
# Using if-else with user input
age = int(input("Enter your age: "))
if age >= 18:
print("You are an adult.")
else:
print("You are a minor.")
# Using logical operators (and, or)
x = 10
y = 25
if x > 0 and y > 0:
print("Both numbers are positive.")
elif x > 0 or y > 0:
print("At least one number is positive.")
else:
print("Both numbers are non-positive.")
Making decisions based on conditions is crucial for controlling the flow of your Python programs and creating dynamic and responsive applications.
