What will be the output produced by following code ?

>>> print (print ("Hola", end = ""))

Carefully look at the following code and its execution on Python shell. Why is the last assignment giving error ?

>>> a = 0o12
>>> print(a)
10
>>> b = 0o13
>>> c = 0o78
    File "<python-input-41-27fbe2fd265f>", line 1
    c = 0o78
         ^
SyntaxError : invalid syntax         

The id( ) can be used to get the memory address of a variable. Consider the adjacent code and tell if the id( ) functions will return the same value or not(as the value to be printed via print() ) ? Why ?
[There are four print() function statements that are printing id of variable num in the code shown on the right.

num = 13
print( id(num) )
num = num + 3
print( id(num) )
num = num - 3
print( id(num) )
num = "Hello"
print( id(num) )

Consider below given two sets of codes, which are nearly identical, along with their execution in Python shell. Notice that first code-fragment after taking input gives error, while second code-fragment does not produce error. Can you tell why ?

(a)

>>> print(num = float(input("value1:")) )  
value1:67

TypeError: 'num' is an invalid keyword argument for this function

(b)

>>> print(float(input("valuel:")) )
value1:67
