## Python Interview Questions

Here are some common interview questions for Python. Remember to prepare for these questions and practice your answers before your interview. Good luck!

**1. Can we give duplicate keys in the dictionary? and what’s the output for the below scenario? **

As a rule, duplicate keys are not allowed. The result of the below scenario is the value will be the last one.

**Scenario:**

dict= {“a”: 1, “b”:2, “a”:5}
print(dict[“a”])

**Output**

5

** Process exited – Return Code: 0 **
Press Enter to exit terminal

**2. How to merge three lists in python?**

You can resolve it by using the ZIP method.

**Scenario:**

a=[1,2,3]

b=[3,4,5]

c=[6,7,8]

new_list=zip(a,b,c)

print(list(new_list))

**Output**

[(1, 3, 6), (2, 4, 7), (3, 5, 8)]

** Process exited – Return Code: 0 **
Press Enter to exit terminal

**4. Why tuple is faster than a list?**

Since a tuple is immutable and stored in a single memory block. So tuple is faster than a list.

**5. What is memory management in python?**

- The garbage collector automatically releases unused objects in one way. The other way is it follows dynamic memory allocation.
- Memory management in Python involves a **private heap** containing all Python objects and data structures. The **Python memory manager** has different components which deal with various dynamic storage management aspects, like** sharing**,** segmentation**, **preallocation, or caching.**
- The management of the Python heap is performed by the interpreter itself and the user has **no control over it.**

**6. What are the popular packages and frameworks in python?**

- NumPy
- Pandas
- SciPy
- Django
- Flask

**7. How python works?**

Python is an[ interpreted language](https://srinimf.com/2021/11/24/13-essential-python-interview-questions/). No need to compile. It works interactively. The syntax is elegant and easy, and simple to use.
