Code Explanation:
1️⃣ Creating an Empty List
a = []
a contains an empty list.
An empty list is falsy in Python.
a → []
bool(a) → False
2️⃣ Creating a String
b = "Python"
b contains the string "Python".
A non-empty string is truthy.
b → "Python"
bool(b) → True
3️⃣ Creating c
c = 0
0 is also falsy.
c → 0
bool(c) → False
4️⃣ Understanding a or b
x = a or b
The or operator works like:
Return the first truthy value.
Check a first:
a → [] → False
So Python moves to b:
b → "Python" → True
Therefore:
x → "Python"
⚠️ Important: or doesn't necessarily return True or False. It can return an actual operand value.
5️⃣ Understanding c or x
y = c or x
Check c:
c → 0 → False
So Python returns the next operand, x.
x → "Python"
Therefore:
y → "Python"
6️⃣ Understanding y and len(y)
z = y and len(y)
The and operator works differently:
If the first value is truthy, evaluate and return the second value.
Here:
y → "Python"
"Python" is truthy, so Python evaluates:
len("Python")
There are 6 characters:
P y t h o n
1 2 3 4 5 6
Therefore:
z → 6
7️⃣ Printing the Result
print(x, z)
We have:
x = "Python"
z = 6
So the final output is:
Python 6
Final Output:
Python 6
