Python Frequently Asked Interview Questions:

  • What are the tools available for identifying bugs & performing static analysis in Python?

We can use tools like PyChecker and Pylint for performing static analysis and linting tools respectively. With PyChecker it becomes easy to find bugs in python source code files. With Pylint, we can we can integrate it with different plugins to enable custom features as well.

  • How will you differentiate between deep & shallow copies.

When it comes to performing tasks like creating new objects and storing references of original elements we will be using Shallow copy. Instead of creating recursion it creates copies of nested objects.

Whereas Deep copy creates an independent and new copy of an object and in addition, it also copies all the nested objects of the original element recursively.

  • How will you define PIP?

Python Installer Package is simply called as PIP. This package is used for installing different python modules. With this command tool, users can have a seamless interface for installing different python modules.

Its syntax is: pip install <package_name>

  • Define PYTHONPATH.

PYTHONPATH can be defined as the environment variable that is used for incorporating additional directories during the import of a module or a package. It checks whether the imported packages or modules are present in the existing directories. It also identifies which module needs to be loaded.

  • What is the easy method to check if all characters in the given string is alphanumeric?

We can simply execute this task using the isalnum() method. If the string consists of only alphanumeric characters it returns ‘True’ as the output if not ‘False’.

For Example –

“abdc1321”.isalnum() #Output: True

“xyz@123$”.isalnum() #Output: False

  • What are Lambda functions?

These functions are generally inline, anonymous functions that are usually represented by a single expression. During the runtime, lambda functions create function objects and they can also accept any given number of parameters.


mul_func = lambda x,y : x*y

print(mul_func(6, 4))

# Output: 24

  • What are Dict and List comprehensions?

In Python, the use of comprehensions like decorators, are syntactic sugar constructs that help build altered and filtered lists, dictionaries, or sets from a given list, dictionary, or set. These comprehensions can save lot time and code.
