Here is the list of Python Interview Questions which are recently asked in Wipro company. These questions are included for both Freshers and Experienced professionals. Our Python Training has Answered all the below Questions.
1. How can we make forms in Python?
To make form in Python
Eg: Login Form using Python Tkinter
User can enter the details for username, password; and click on Login button. Once the button is clicked, a function is called to validate the credentials. Here, in this function, you have to write your business logic to validate the username and password.
2. What are the benefits of Python?
Easier to learn, write and understand the code - Python is really easy to pick up and learn similar to English language, so lot of people recommend Python to beginners
Improved Productivity - Due to the simplicity of Python, developers can focus on solving the problem by writing less code and more time on productivity.
Interpreted Language - Python executes the code directly in a line by line manner.
Dynamically Typed - It automatically assigns the data type during execution.
Free and Open-Source – Python is a OSI approved open-source which makes it free to use.
Vast Libraries Support - The standard library of Python is huge with almost all the functions needed for your task without the use of external library.
Portability - You only write once and run it anywhere.
3. What are the key features of Python?
- Easy to code and use
- Free and Open Source
- Object-Oriented and high level Language
- GUI Programming Support
- Extensible feature
- Portable and Integrated language
4. What type of language is Python? Programming or Scripting?
Python is considered a scripting language because of a historical blur between scripting languages and general purpose programming languages. In fact, Python is not a scripting language, but a general purpose programming language that also works nicely as a scripting language. It is also an interpreted and high-level programming language for the purpose of general programming requirements.
5. What are the applications of Python?
- Web and Internet Development
- Scientific and Numeric Applications
- Education and training programs
- Artificial intelligence and Machine learning
- Software and Game Development
- Business Application
6. What is the difference between list and tuple in Python?
Lists and tuples are data structures in Python whereas the main difference is lists are mutable while tuples are immutable. A list has a variable size while a tuple has a fixed size.
7. What are the global and local variables in Python?
There are two types of variables: global variables and local variables. The scope of global variables is the entire program whereas the scope of local variable is limited to the function where it is defined.
8. How can Python be an interpreted language?
Python is called an interpreted language because it goes through an interpreter, which turns code you write into the language understood by your computer's processor.
9. What is a boolean in Python?
The python data type bool is used to store two values i.e. True and False. Bool is used to test whether the result of an expression is true or false.
10. Define Python Path?
PYTHON PATH is an environment variable which you can set to add additional directories where python will look for modules and packages. For most installations, you should not set these variables since they are not needed for Python to run. Python knows where to find its standard library.
11. What are the two major loop statements?
The group of statements being executed repeatedly is called a loop. There are two loop statements in Python: for and while.
12. How memory management is done in Python?
Memory management in Python involves a private heap containing all Python objects and data structures. The management of this private heap is ensured internally by the Python memory manager.
The Python memory manager has different components which deal with various dynamic storage management aspects, like sharing, segmentation, reallocation or caching
13. What are the built-in types available in Python?
Python uses five numeric types: Booleans, integers, long integers, floating-point numbers, and complex numbers. Except for Booleans, all numeric objects are signed.
14. Define String in Python?
A string in Python is a sequence of characters. It is a derived data type. Strings are immutable. This means that once defined, they cannot be changed.
15. How do you create a Python function?The steps to defining a function in Python are the following:
- Use the keyword def to declare the function and follow this up with the function name.
- Add parameters to the function: they should be within the parentheses of the function.
- Add statements that the functions should execute.
16. How does a function return values?
A return statement is used to end the execution of the function call and “returns” the result (value of the expression following the return keyword) to the caller. The statements after the return statements are not executed
17. Write Python code to sort a numerical dataset?
#Get input from user number=int(input("Enter any number :")) #store a copy of this number temp=number #calculate reverse of this number reverse_num=0 while(number>0): #extract last digit of this number digit=number%10 #append this digit in reveresed number reverse_num=reverse_num*10+digit #floor divide the number leave out the last digit from number number=number//10 #compare reverse to original number if(temp==reverse_num): print("The number is palindrome!") else: print("Not a palindrome!")
18. Why do we use the split method in Python?
Split Function is In-Build function of Python String Data Type, The Main purpose of split data type is to separate the string into different elements, and the separated string will actually store in the format of List datatype.
19. What are Dict and List comprehensions in Python?
In Python, dictionary comprehensions are very similar to list comprehensions – only for dictionaries. They provide an elegant method of creating a dictionary from an iterable or transforming one dictionary into another.Using an if statement allows you to filter out values to create your new dictionary.
20. How do we convert the string to lowercase?
lower() method returns the lowercased string from the given string. It converts all uppercase characters to lowercase. If no uppercase characters exist, it returns the original string.
