What is Python? <\/h3>\n\n\n\n

These days, Python is one of the most broadly used programming languages. It was developed by Guido van Rossum<\/strong><\/a> and was released in 1991<\/strong>. It\u2019s a general-purpose, interpreter, high-level, interactive, object-oriented scripting language.<\/p>\n\n\n\n

It consists of modules, objects, threads, and automatic memory management. It takes into consideration a plethora of programming paradigms, including structured, object-oriented, and functional programming. Python is often referred to as a “batteries included”<\/strong> language due to its large standard library.<\/p>\n\n\n\n

Is Python a case-sensitive language? <\/h3>\n\n\n\n

Yes, it is a case-sensitive programming language.<\/p>\n\n\n\n

State some features of Python. <\/h3>\n\n\n\n

Python is:-<\/p>\n\n\n\n

    \n
  1. Interpreted<\/li>\n\n\n\n
  2. Dynamically typed<\/li>\n\n\n\n
  3. Object-oriented<\/li>\n\n\n\n
  4. Cross-platform<\/li>\n\n\n\n
  5. General-purpose language<\/li>\n<\/ol>\n\n\n\n

It can function effectively on various platforms such as Linux, Macintosh, UNIX, and Windows<\/strong>. It can also easily be amalgamated with C++, C, COM, and ActiveX.<\/strong><\/p>\n\n\n\n

    How Python is an Interpreted Language?<\/strong> <\/h3>\n\n\n\n

    In layman’s terms<\/strong>, interpreted language means executing a program by reading the source code line by line. Python is considered an interpreted language because it runs directly from the source code.
    Code is required whenever Python programs are executed. The main function Python does is that it simply converts the source code written by the programmer into an in-between language. This is again translated into the native language that is eventually executed. It is primarily done at runtime by the interpreter<\/p>\n\n\n\n

    Describe some benefits of using Python. <\/h3>\n\n\n\n

      2. Not efficient when it comes to mobile development<\/li>\n\n\n\n
      3. Memory consumption is high for Python, so for memory-intensive tasks, Python is not preferable<\/li>\n\n\n\n
      4. The access layer of Python is a bit old and underdeveloped<\/li>\n\n\n\n
      5. Python\u2019s design has multiple issues<\/li>\n\n\n\n
      6. The syntax is so simple that programmers often get accustomed to using Python and often a times face difficulty in learning other programming languages.<\/li>\n<\/ol>\n\n\n\n

        Python supports what sorts of data types? <\/strong><\/h3>\n\n\n\n
          \n
        1. Numbers<\/li>\n\n\n\n
        2. String<\/li>\n\n\n\n

          Python supports which databases? <\/h3>\n\n\n\n

          Most prominently Python supports-<\/p>\n\n\n\n

            \n
          1. MySQL (Structured)<\/li>\n\n\n\n
          2. MongoDB (Unstructured) databases.<\/li>\n<\/ol>\n\n\n\n

            Which different file processing modes are supported by Python? <\/h3>\n\n\n\n
              \n
            1. Read-only mode:<\/strong> It is the default mode and opens the file for reading.<\/li>\n\n\n\n
            2. Write-only mode:<\/strong> It opens a file for writing. If there is any data in the file it\u2019ll be lost and a new file will be created.<\/li>\n\n\n\n
            3. Read-Write mode: <\/strong>It is often referred to as updating mode. It enables both reading and writing.<\/li>\n\n\n\n
            4. Append mode<\/strong>: It opens the file for writing. It adjoins to the end of the file if the file exists.<\/li>\n\n\n\n
            5. Which tools help in finding bugs in Python?<\/strong><\/li>\n<\/ol>\n\n\n\n

              Various tools are available in Python which helps in finding bugs. The most popular tools are- PyChecker<\/a> and Pylint<\/a>.<\/p>\n\n\n\n

              What is PYTHONPATH? <\/h3>\n\n\n\n

              PYTHONPATH is an environment variable and is installed to add additional directories. Python will search for modules and packages in these additional directories. The main use of PYTHONPATH is when the user is creating some code that she wants to import from Python.<\/p>\n\n\n\n

              How is memory managed in Python? <\/h3>\n\n\n\n

              Private heap<\/strong> space is responsible for managing Python\u2019s memory. It consists of all Python objects and data structures. The Python interpreter takes care of this private heap space. Python\u2019s in-built garbage collector makes memory available for private heap space by recycling and freeing up all the unused memory.<\/p>\n\n\n\n

              How to comment on multiple lines in Python? <\/h3>\n\n\n\n

              The comment refers to a piece of text in a computer application that is meant to explain the source code. In Python, the symbol # is used to comment on multiple lines.<\/p>\n\n\n\n

              What are docstrings in Python? <\/h3>\n\n\n\n

              Documentation strings (or docstrings) are string literal in Python. These are utilized in the class, module, function, or method definition. They appear right after defining class, module, and function.<\/p>\n\n\n\n

              What are pickling and unpickling?<\/strong> <\/h3>\n\n\n\n

              Pickling in Python enables the programmer to serialize objects into binary systems whereas Unpickling refers to the exact opposite of Pickling. It allows users to de-serialize objects into binary systems.<\/p>\n\n\n\n

              What is a namespace in Python? <\/h3>\n\n\n\n

              A namespace in Python ensures that all the names used in a program are distinct. In Python, each package, module, class, function, and method function has its own “namespace”. Amusing facts about Python is that it executes namespaces as dictionaries. Some examples are – local namespace, Global namespace, and built-in namespace.<\/p>\n\n\n\n

              What is an operator in Python? <\/h3>\n\n\n\n

              Operators are special symbols in Python. These are used to perform operations on different values and variables.<\/p>\n\n\n\n

              Different types of operators that are present in Python are as follows:-<\/p>\n\n\n\n

              \u2022 Arithmetic operators<\/strong><\/p>\n\n\n\n

              These are used to check if two values are located in some part of the memory.<\/p>\n\n\n\n

              \u2022 Membership Operators<\/strong><\/p>\n\n\n\n

              These are used to ensure whether a value or a variable is present in a sequence.<\/p>\n\n\n\n

              \u2022 Bitwise Operators<\/strong><\/p>\n\n\n\n

              These act on bits and perform bit-by-bit operations.<\/p>\n\n\n\n

              How can you distinguish between .pyc and .py files? <\/h3>\n\n\n\n

              .pyc contains the program\u2019s bytecode on the other hand .py file contains the source code of the program.<\/p>\n\n\n\n

              How will you distinguish between NumPy and SciPy? <\/h2>\n\n\n\n

              NumPy stands for Numerical Python while SciPy stands for Scientific Python. The main distinction is that NumPy is used for the manipulation of data in Python whereas SciPy refers to a collection of tools that aids Python in integration, differentiation, etc.<\/p>\n\n\n\n

              What do you understand by slicing in Python? <\/h3>\n\n\n\n

              Slicing is primarily concerned with returning the value of the sub-string from the main string. It consists of a start, stops, and step value.<\/p>\n\n\n\n

              Syntax<\/h3>\n\n\n\n

              slice(start<\/em>, end, step<\/em>)<\/p>\n\n\n\n
