In Python, conditional statements are used to make decisions based on certain conditions. The most common type of conditional statement is the if
statement. Here’s an overview of Python conditions and if statements:
if statement: The if
statement is used to execute a block of code only if a specified condition is true. It has the following syntax:
if condition:
# code block to execute if condition is true
elif statement: The elif
statement allows you to check multiple conditions one after the other. It is short for “else if” and is used when you want to check additional conditions if the previous ones are false. It has the following syntax:
if condition1:
# code block to execute if condition1 is true
elif condition2:
# code block to execute if condition2 is true and condition1 is false
else:
# code block to execute if all conditions are false
else statement: The else
statement is used to execute a block of code if none of the preceding conditions are true. It is optional and always comes at the end of an if statement. It has the following syntax:
if condition:
# code block to execute if condition is true
else:
# code block to execute if condition is false
Here’s a simple example demonstrating the use of if statements in Python:
x = 10
if x > 5:
print("x is greater than 5")
elif x == 5:
print("x is equal to 5")
else:
print("x is less than 5")
