![What is the major difference between tuples and lists in Python?
Tuples Lists
Tuples are similar to a list, but they are
enclosed within parenthesis, unlike the
list.
The list is used to create a
sequence.
The element and size can be changed.
The element and size
cannot be changed.
They cannot be updated. They can be updated.
They act as read-only lists.
They act as a changeable
list.
Tuples are surrounded by ( ) Lists are surrounded by [ ]
Example of Tuple Code is, tup = (1, "a",
"string", 1+2)
Example of Lists Code is, L
= [1, "a" , "string" , 1+2]
What can be the length of the identifier in Python?
The length of the identifier in Python can be of any length. The longest identifier will
violate from PEP – 8 and PEP – 20.
Define Pass statement in Python?
A Pass statement in Python is used when we cannot decide what to do in our code, but
we must type something for making syntactically correct.
How many ways can be applied for applying reverse string?
There are five ways in which the reverse string can be applied which include the
following.
1. Loop
2. Recursion
3. Stack
4. Extended Slice Syntax
5. Reversed](https://image.slidesharecdn.com/pythoninterviewquestionsforfreshers-220111061715/85/Python-Interview-Questions-For-Freshers-2-320.jpg)
Python Interview Questions For Freshers
- 1. Python Interview Questions for Freshers Explain Python? Python is a highly comprehensive, interactive, and object-oriented scriptwriting language. It is specifically developed with the purpose of making the content highly readable among the net surfers. Python makes use of various English keywords other than just punctuations. It also has lesser syntactical constructions like in other languages. What is Pythonpath? A Pythonpath tells the Python interpreter to locate the module files that can be imported into the program. It includes the Python source library directory and source code directory. Why do we use Pythonstartup environment variable? We use the Pythonstartup environment variable because it consists of the path in which the initialization file carrying Python source code can be executed to start the interpreter. What is the Pythoncaseok environment variable? Pythoncaseok environment variable is applied in Windows with the purpose to direct Python to find the first case insensitive match in an import statement. What are the supported standard data types in Python? The supported standard data types in Python include the following. 1. List. 2. Number. 3. String. 4. Dictionary. 5. Tuples. Define tuples in Python? Tuples is a sequence data type in Python. The number of values in tuples are separated by commas.

- 3. What is the purpose of relational operators in Python? The purpose of relational operators in Python is to compare values. What are assignment operators in Python? The assignment operators in Python can help in combining all the arithmetic operators with the assignment symbol. Why do we need membership operators in Python? We need membership operators in Python with the purpose to confirm if the value is a member in another or not. How are identity operators different than the membership operators? Unlike membership operators, the identity operators compare the values to find out if they have the same value or not. Can we use a break and continue together in Python? How? Break and continue can be used together in Python. The break will stop the current loop from execution, while jump will take to another loop. Explain how is it possible to Get the Google cache age of any URL or webpage using Python. In order to Get the Google cache age of any URL or webpage using Python, the following URL format is used: http://webcache.googleusercontent.com/search?q=cache:URLGOESHERE Simply replace URLGOESHERE with the web address of the website or webpage whose cache you need to retrieve and see in Python.
