1. What is Python? List some popular applications of Python in the world of technology.
Python is a widely-used general-purpose, high-level programming language. It was created by Guido van Rossum in 1991 and further developed by the Python Software Foundation. It was designed with an emphasis on code readability, and its syntax allows programmers to express their concepts in fewer lines of code. It is used for: 1. System Scripting 2. Web Development 3. Game Development 4. Software Development 5. Complex Mathematics
2. What are the benefits of using Python language as a tool in the present scenario?
The following are the benefits of using Python language: 1. Object-Oriented Language 2. High-Level Language 3. Dynamically Typed language 4. Extensive support Libraries 5. Presence of third-party modules 6. Open source and community development 7. Portable and Interactive 8. Portable across Operating systems
3. Is Python a compiled language or an interpreted language?
Actually, Python is a partially compiled language and partially interpreted language. The compilation part is done first when we execute our code and this will generate byte code internally this byte code gets converted by the Python virtual machine(p.v.m) according to the underlying platform(machine+operating system).
24. What is the difference between xrange and range functions?
range() and xrange() are two functions that could be used to iterate a certain number of times in for loops in Python. 1. In Python 3, there is no xrange, but the range function behaves like xrange. 2. In Python 2 2.1. range() – This returns a range object, which is an immutable sequence type that generates the numbers on demand. 2.2. xrange()– This function returns the generator object that can be used to display numbers only by looping. The only particular range is displayed on demand and h...
25. What is Dictionary Comprehension? Give an Example
Dictionary Comprehension is a syntax construction to ease the creation of a dictionary based on the existing iterable. For Example: my_dict = {i:i+7 for i in range(1, 10)}
26. Is Tuple Comprehension? If yes, how, and if not why?
Tuple comprehension is not possible in Python because it will end up in a generator, not a tuple comprehension.
42. What is PIP?
PIP is an acronym for Python Installer Package which provides a seamless interface to install various Python modules. It is a command-line tool that can search for packages over the internet and install them without any user interaction.
43. What is a zip function?
Python zip() function returns a zip object, which maps a similar index of multiple containers. It takes an iterable, converts it into an iterator and aggregates the elements based on iterables passed. It returns an iterator of tuples.
44. What are Pickling and Unpickling?
The Pickle module accepts any Python object and converts it into a string representation and dumps it into a file by using the dump function, this process is called pickling. While the process of retrieving original Python objects from the stored string representation is called unpickling.

- What is the difference between a list and a tuple? List. Tuple. A list consists of mutable objects. (Objects which can be changed after creation)
- How would you convert a list into a tuple? my_list = [50, "Twenty", 110, "Fifty", "Ten", 20, 10, 80, "Eighty"] my_tuple = (my_list[0], my_list[len(my_list) - 1], len(my_list)) print(my_tuple)
- What is the difference between an array and a list? List. Array. Python lists are very flexible and can hold arbitrary data. Python arrays are just a thin wrapper on C arrays.
- How would you convert a list to an array? During programming, there will be instances when you will need to convert existing lists to arrays in order to perform certain operations on them (arrays enable mathematical operations to be performed on them in ways that lists do not).
