Programming in Python (IT-605) - Important Questions

Write a Python program to define and use functions demonstrating parameter passing (positional, keyword, default), return values, and a brief explanation of the function definition syntax using examples.

Write Python programs to demonstrate the following string operations: concatenation, slicing, formatting, searching (find/index), and common methods (split, join, replace). Predict outputs for given examples and explain immutability of strings.

Explain the standard data types available in Python with examples: int, float, bool, str, list, tuple, set, dict. Include sample literal representations and typical use-cases for each type.

Write a Python program to demonstrate list operations: append, extend, insert, pop, remove, slicing, and list comprehension. Provide sample input and predict the output after each operation.

Explain the syntax and usage of the if, if-else, and if-elif-else statements in Python. Provide example programs that illustrate nested conditionals and use of logical operators.

Draw a flowchart and write the corresponding Python program for a given algorithm (for example: find the largest of three numbers or compute factorial). Explain the flow-control steps in the flowchart with reference to the code.

Define Python identifiers. State the rules for naming identifiers in Python and give examples of valid and invalid identifiers. Explain the significance of case-sensitivity.

List and explain the types of operators in Python (arithmetic, relational, logical, bitwise, assignment, membership, identity) with short examples showing their use and typical precedence.

Write a Python program to demonstrate creation, access, modification, and common methods of a dictionary. Include examples of iterating over keys, values, and items, and explain when to use a dictionary.

Describe the steps to set up a local Python development environment on Windows/Linux: installing Python, configuring PATH, creating and activating virtual environments, and installing packages using pip.

Explain Python tuples and contrast them with lists. Provide examples showing tuple creation, indexing, slicing, immutability, and use-cases where tuples are preferred over lists.

Explain the features of a typical Python IDE (such as PyCharm, VS Code or IDLE). Demonstrate how to create, run, and debug a simple Python program using an IDE.

Write Python examples showing data type conversion (casting) between common types: int, float, str, and bool. Explain implicit vs explicit conversion and pitfalls to watch for.
