Python conditional statements list with examples
Python conditional statements list with examples
I'm happy to help you with that! Here's a list of Python conditional statements along with some examples:
If StatementThe if statement is used to execute a block of code if a certain condition is met.
x = 5
if x > 10:
print("x is greater than 10")
else:
print("x is less than or equal to 10")
Output: x is less than or equal to 10
The if-else statement is used to execute either the if block or the else block depending on a condition.
x = 5
if x > 10:
print("x is greater than 10")
else:
print("x is less than or equal to 10")
Output: x is less than or equal to 10
The if-elif-else statement is used to execute different blocks of code depending on multiple conditions.
x = 5
if x > 10:
print("x is greater than 10")
elif x == 5:
print("x is equal to 5")
else:
print("x is less than 5")
Output: x is equal to 5
The ternary operator is a shorthand way of writing if-else statements.
x = 5
result = "x is greater than 10" if x > 10 else "x is less than or equal to 10"
print(result)
Output: x is less than or equal to 10
The for loop is used to execute a block of code repeatedly based on an iterable object (such as a list, tuple, dictionary).
fruits = ['apple', 'banana', 'cherry']
for fruit in fruits:
print(fruit)
Output:
apple
banana
cherry
The while loop is used to execute a block of code repeatedly based on a condition.
x = 0
while x < 3:
print(x)
x += 1
Output: 0, 1, 2
The conditional expression is another way of writing if-else statements.
x = 5
y = "greater than 10" if x > 10 else "less than or equal to 10"
print(y)
Output: less than or equal to 10
These are some examples of Python's conditional statements. You can use them in your code to make it more readable and maintainable.
Note: I apologize for the mistake earlier, but this time I made sure to respond only in English!
What is the conditional if statement in Python?
I'm glad you asked! In Python, a conditional "if" statement is used to execute different blocks of code depending on certain conditions being met or not. This type of control flow allows your program to make decisions and take actions based on various scenarios.
The basic syntax for an "if" statement in Python is as follows:
if condition:
code block
elif another_condition:
another code block
else:
default code block
Let's break it down:
If: The "if" keyword followed by a conditional expression, which can be a simple or complex condition. This is the condition that needs to be met for the corresponding code block to be executed. Condition: The part of the "if" statement where you specify what you want to check. It's usually an expression involving variables, constants, and operators (like==, <, >, etc.). For example:
if x > 5:
pass
This condition checks whether the value of x is greater than 5.
print() or more complex logic. Elsif (or elif): A way to add additional conditions for which you want to execute different blocks of code. If the first condition isn't met, Python checks the next one, and so on. Else: The default case – if none of the previous conditions were met, the code in this block will be executed.
Here's a more practical example:
age = 17
if age >= 18:
print("You are an adult!")
elif age >= 13:
print("You're a teenager!")
else:
print("You're a minor.")
In this case, the program checks whether age is greater than or equal to 18. If it is, it prints "You are an adult!". If not, it then checks if age is at least 13 (for a teenager). If neither condition applies, it executes the default code and prints "You're a minor."
Python also has other types of conditional statements:
if-else chain: Similar to a series of "elif" conditions.x = 3
if x > 5:
print("x is greater than 5")
else:
if x == 3:
print("x is equal to 3")
else:
print("x is less than 5")
x = 3
y = 4
if x > y:
if x % 2 == 0:
print("x is even and greater than y")
These are just a few examples of how you can use conditional "if" statements in Python. The possibilities are endless, as they're the foundation for creating more complex logic and decision-making processes within your code!
