The function changes a copy of x, not the original variable. While x's value changes inside the function, the returned value is not stored anywhere, hence print(x) prints the original value of x.
The Output:
x = 7
if x > 10:
print("A")
elif x > 5:
if x < 8:
print("B")
else:
print("C")
else:
print("D")
What is “B”?
