Python Coding challenge - Day 1192| What is the output of the following Python Code?

Code Explanation:

🔹 1. Creating a List

nums = [2, 4, 6, 8]

✅ Explanation:

A list named nums is created containing four numbers.

Current list:

[2, 4, 6, 8]

Visual:

Index : 0  1  2  3

Value : 2  4  6  8

🔹 2. Calling all()

result = all(

✅ Explanation:

all() is a built-in Python function.

It checks whether every element in an iterable is True.

If all values are True, it returns True.

If even one value is False, it immediately returns False.

Syntax:

all(iterable)

🔹 3. Generator Expression

x % 2 == 0

for x in nums

✅ Explanation:

This is a generator expression.

It checks every number in the list.

Condition:

x % 2 == 0

means:

Is the number even?

Equivalent loop:

for x in nums:

    print(x % 2 == 0)

🔹 4. First Iteration

Current value:

x = 2

Calculation:

2 % 2

Result:

0

Condition:

0 == 0

Result:

True ✅

🔹 5. Second Iteration

Current value:

x = 4

Calculation:

4 % 2

Result:

0

Condition:

0 == 0

Result:

True ✅

🔹 6. Third Iteration

Current value:

x = 6

Calculation:

6 % 2

Result:

0

Condition:

0 == 0

Result:

True ✅

🔹 7. Fourth Iteration

Current value:

x = 8

Calculation:

8 % 2

Result:

0

Condition:

0 == 0

Result:

True ✅

🔹 8. Final Decision of all()

Results obtained:

True

True

True

True

Since every value is True, all() returns:

True

Stored in:

result

Current state:

result = True

🔹 9. Printing the Result

print(result)

✅ Explanation:

Python prints the value stored in result.

Output:

True

🎯 Final Output

True
