🚀 Day 48/150 – Count Even and Odd Numbers in a List in Python

Counting even and odd numbers in a list helps you practice loops, conditions, and list handling.

 Even numbers are divisible by 2
 Odd numbers are not divisible by 2

Example:
[1, 2, 3, 4, 5] → Even = 2, Odd = 3

Let’s explore different ways 👇

🔹 Method 1 – Using for Loop

numbers = [1, 2, 3, 4, 5]

even = 0
odd = 0

for num in numbers:
    if num % 2 == 0:
        even += 1
    else:
        odd += 1

print("Even:", even)
print("Odd:", odd)






✅ Most common method.

🔹 Method 2 – Taking User Input

numbers = list(map(int, input("Enter numbers: ").split()))

even = odd = 0

for num in numbers:
    if num % 2 == 0:
        even += 1
    else:
        odd += 1

print("Even:", even)
print("Odd:", odd)






✅ Dynamic input.

🔹 Method 3 – Using List Comprehension

numbers = [1, 2, 3, 4, 5]

even = len([num for num in numbers if num % 2 == 0])
odd = len([num for num in numbers if num % 2 != 0])

print("Even:", even)
print("Odd:", odd)

✅ Clean and Pythonic.

🔹 Method 4 – Using while Loop

numbers = [1, 2, 3, 4, 5] i = 0 even = odd = 0 while i < len(numbers): if numbers[i] % 2 == 0: even += 1 else: odd += 1 i += 1 print("Even:", even) print("Odd:", odd)

✅ Loop practice.

any(x)

🧩 What any() Does

any() checks values one by one.

Stops immediately when it finds first truthy value ✅

🔹 Step 2.1: First Value

0

👉 0 is falsy ❌

Continue checking.

🔹 Step 2.2: Second Value

0

👉 Again falsy ❌

Continue.

🔹 Step 2.3: Third Value

5

👉 5 is truthy ✅

So:

any(x) → True

Generator stops HERE.

Consumed values:

0, 0, 5

Remaining value:

0

🔹 Step 3: Execute next(x)

next(x)

Generator already consumed:

0,0,5

Only remaining value:
