Mastering conditions and loops in Python is essential for controlling program flow and repeating tasks efficiently. Ready to dive in? Let's break it down step-by-step!
1. If-Else Conditions
The if-else
statement lets your program make decisions. If a condition is True
, a block of code runs; otherwise, the else
block executes.
Example: Check Voter Eligibility by Age
age = 20
if age >= 18:
print("You are eligible to vote.")
else:
print("You are not eligible to vote.")
2. Elif: Handling Multiple Conditions
The elif
statement allows you to check multiple conditions sequentially. If the first condition is False
, Python checks the next one.
Example: Finding the Greatest Number
num1, num2, num3 = 5, 10, 3
if num1 > num2 and num1 > num3:
print("num1 is the greatest")
elif num2 > num3:
print("num2 is the greatest")
else:
print("num3 is the greatest")
3. For Loops
The for
loop repeats a block of code for a specific number of iterations. Ideal when you know how many times you want to loop through a sequence.
Example: Looping with a Range
for i in range(1, 11):
print(i)
4. While Loops
The while
loop continues to execute a block of code as long as a specified condition is True
. Useful when the number of iterations is unknown.
Example: While Loop Counting to 10
i = 1
while i <= 10:
print(i)
i += 1
Conditions and loops are the backbone of decision-making and repetition in Python. Mastering if-else
, elif
, for
, and while
loops will elevate your coding skills.
