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
