Question 4) What do you mean by Python literals?
Answer: In Python, literals are the raw values or data that are used to represent a specific type of data. They are the fixed values that are used to directly assign to variables or to be used as inputs in expressions and operations. In other words, literals are the fundamental building blocks of Python programs.

Python supports various types of literals, including:

  • Numeric literals, such as integers, floating-point numbers, and complex numbers
  • String literals, which are used to represent textual data
  • Boolean literals, which are used to represent the truth values of True and False
  • Sequence literals, such as lists, tuples, and range objects
  • Mapping literals, such as dictionaries
  • Set literals, which are used to represent sets of unique elements
  • None literal, which is used to represent the absence of a value

def isRotated(str1, str2):

    if (len(str1) != len(str2)):
        return False
    
    if(len(str1) < 2):
        return str1 == str2
    clock_rot = ""
    anticlock_rot = ""
    l = len(str2)

    #  anti-clockwise rotation
    anticlock_rot = (anticlock_rot + str2[l - 2:] +
                                    str2[0: l - 2])
    
    #  clock wise rotation
    clock_rot = clock_rot + str2[2:] + str2[0:2]


    return (str1 == clock_rot or
            str1 == anticlock_rot)

# Driver code
if __name__ == "__main__":
    
    str1 = "prepbytes"
    str2 = "epbytespr"
if isRotated(str1, str2):
    print("Yes")
else:
    print("No")


Output

Yes

remove() function:

  • Removes the first occurrence of a specified element from a list based on its value.
  • Modifies the list in place and returns the modified list.
  • Raises a ValueError if the specified element is not found in the list.

del statement:

  • Removes a specific element from a list based on its index.
  • Modifies the list in place and does not return anything.
  • Raises an IndexError if the specified index is out of range.

Question 9) What is the output of print tuple if tuple = ( ‘abcd’, 786 , 2.23, ‘john’, 70.2 )?
Answer: The output is

('abcd', 786, 2.23, 'john', 70.2)

Question 10) What is NumPy and How is it Better than a List in Python?
Answer: NumPy is a popular numerical computing library for Python that provides support for large, multi-dimensional arrays and matrices, as well as a variety of mathematical operations to work with them efficiently.

Question 11) Is python a case-sensitive language?
Answer: Yes, Python is a case-sensitive language. This means that Python distinguishes between uppercase and lowercase letters in its syntax. For example, the variable names "myVar" and "myvar" are considered different variables in Python, and referring to them in the wrong case can lead to errors in your code.

Question 12) What is a tuple in Python?
Answer: In Python, a tuple is an ordered collection of values, similar to a list. However, tuples are immutable, which means that once a tuple is created, its values cannot be changed. Tuples are often used to group related values together, particularly when those values are not expected to change. They can also be used as keys in dictionaries, which require immutable objects as keys.

Question 13) What are the different file processing modes supported by Python?
Answer: Python supports several file processing modes that determine how a file can be opened and read or written to. The different file processing modes in Python are:

  • "r" (Read mode): This is the default mode and it is used to open a file for reading. You can read the contents of the file, but you cannot modify it.
  • "w" (Write mode): This mode is used to open a file for writing. If the file already exists, its contents will be erased. If the file does not exist, it will be created.
  • "a" (Append mode): This mode is used to open a file for appending. If the file exists, new data will be written to the end of the file. If the file does not exist, it will be created.
  • "x" (Exclusive creation mode): This mode is used to create a new file. If the file already exists, an error will be raised.
  • "b" (Binary mode): This mode is used to open a file in binary mode, which means that the file will be read or written as a binary file. This mode is used when working with non-text files such as images, audio files, and videos.
  • "t" (Text mode): This mode is used to open a file in text mode, which means that the file will be read or written as a text file. This mode is used when working with text files such as .txt files.

These modes can be combined to create different types of file processing modes. For example, "rb" can be used to open a file in binary mode for reading, and "wt" can be used to open a file in text mode for writing.

Question 14) Are there any interfaces to database packages in Python?
Answer: Yes, there are many interfaces to database packages in Python. Python provides several modules for working with databases, which make it easy to interact with a wide variety of database systems from within Python.

Here are some of the most popular Python database modules:

  • SQLite3: This module provides an interface to the SQLite database system, which is a lightweight, file-based database that is often used for small-scale applications.
  • MySQL Connector/Python: This module provides an interface to the MySQL database system, which is one of the most widely used open-source relational database systems.
  • psycopg2: This module provides an interface to the PostgreSQL database system, which is another popular open-source relational database system.
