Python Fundamentals — Question 3

The call to print function is missing parenthesis. The correct way to call print function is this:
print(temperature)

(ii)

a = 30
b=a+b
print (a And b)

There are two errors in this code fragment:

1. In the statement b=a+b variable b is undefined.
2. In the statement print (a And b), And should be written as and.

(iii)

a, b, c = 2, 8, 9
print (a, b, c)
c, b, a = a, b, c
print (a ; b ; c)

In the statement print (a ; b ; c) use of semicolon will give error. In place of semicolon, we must use comma like this print (a, b, c)

(iv)

X = 24
4 = X

The statement 4 = X is incorrect as 4 cannot be a Lvalue. It is a Rvalue.

(v)

print("X ="X)

There are two errors in this code fragment:

1. Variable X is undefined
2. "X =" and X should be separated by a comma like this print("X =", X)

(vi)

else = 21 - 5

else is a keyword in Python so it can't be used as a variable name.
