Assertion (A): Indentation is a very important factor while writing a program in Python.

Reasoning (R): Indentation refers to the spaces at the beginning of a code line. Multiple statements with the same indent are classified as a block of code.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

What are compound statements?

Find error in the following code (if any) and correct it by rewriting the code and underline the corrections:

code=input ("Enter season code : ")
if code=w:
   print "winter season" 
elif code==r:
   PRINT "rainy season" 
else:
   Print "summer season"

Give the output of the following when num1 = 4, num2 = 3, num3 = 2.

num1 += num2 + num3
print(num1)
