Question 1

What is the output of the following?
X = ['ab', 'cd']
Print(len(list(map(list, x))))
A)2
B)4
C)error
D)none of the mentioned

Accepted Answer

map() function returns an iterator, so we need to convert it to a list using list() function.len() function returns the length of the list, which is 2.

Question 2

Program code making use of a given module is called a ______ of the module.
A)Client
B)Docstring
C)Interface
D)Modularity

Accepted Answer

A client of a module refers to any program code that makes use of that module, relying on its functionality. The term emphasizes the relationship where the module serves as a service provider, and the program using it is the consumer or client.

Question 3

What is the output of the following piece of code?
#mod1
Def change(a):
B=[x*2 for x in a]
Print(b)
#mod2
Def change(a):
B=[x*x for x in a]
Print(b)
From mod1 import change
From mod2 import change
#mains=[1,2,3]
Change(s)
A)[2,4,6].
B)[1,4,9].
C)[2,4,6]
D)There is a name clash

Accepted Answer

There is a name clash because the function `change` is defined in both `mod1` and `mod2`, and the second import overwrites the first one.

Question 4

What is the output of the following program?
Tday=datetime.date.today()
Print(tday.month())
A)August
B)Aug
C)08
D)8

Accepted Answer

The correct method to get the month from a date object in Python's datetime module is by accessing the `month` attribute, not by calling it as a method. Therefore, the correct syntax should be `tday.month` without parentheses. This returns the month as an integer, so if the code were corrected to `print(tday.month)`, and assuming today's month is August, the output would be `8`, not `8.` as a float or any of the string representations. However, the provided code has a syntax error due to `Print` being capitalized and the incorrect call of `month` as a method. If corrected for the purpose of understanding the intended output related to month representation, the answer focuses on the integer output.

Question 5

Which of the following formatting options can be used in order to add „n? blank spaces after a given string „S??
A)print("-ns"%S)
B)print("-ns"%S).
C)print("%ns"%S)
D)print("%-ns"%S)

Accepted Answer

The correct formatting option to add "n" blank spaces after a given string "S" is by using the format specifier "%-ns" in Python. This specifier aligns the string to the left and adds "n" blank spaces after it.

Question 6

What is the output of the following program?
F = None
For i in range (5):
With open("data.txt", "w") as f:
If i > 2:break
Print(f.closed)
A)True
B)False
C)None
D)Error

Accepted Answer

The file is closed when the `with` block ends, so the output is `True`.

Question 7

To read the entire remaining contents of the file as a string from a file object infile, we use
A)infile.read(2)
B)infile.read()
C)infile.readline()
D)infile.readlines()

Accepted Answer

The method infile.read() without any argument reads the entire remaining contents of the file as a string, making option B correct.

Question 8

Suppose t = (1, 2, 4, 3), which of the following is incorrect?
A)print(t[3])
B)t[3] = 45
C)print(max(t))
D)print(len(t))

Accepted Answer

Option B is incorrect because tuples in Python are immutable, meaning their elements cannot be changed after the tuple has been created. Attempting to assign a new value to an element of a tuple, as done in option B, will result in a TypeError.

What is the output of the following? X = ['ab', 'cd'] Print(len(list(map(list, x) ) ) )

Program code making use of a given module is called a ______ of the module.

What is the output of the following piece of code? #mod1 Def change(a) : B=[x2 for x in a] Print(b) #mod2 Def change(a) : B=[xx for x in a] Print(b) From mod1 import change From mod2 import change #mains=[1,2,3] Change(s)
