    Study Notes

    Python Programming Basics

    • Python supports conditional statements like if, elif, else for decision making in the program
    • The while loop in Python executes a group of statements as long as a condition is true and is suitable for indefinite loops
    • Logical expressions in Python use relational operators like ==, !=, <, >, etc., and can be combined with logical operators like and, or, not
    • Loop control statements in Python include break, continue, and pass for altering the flow of loops
    • Python has for loops for iterating through a list of values, and range(N) generates a list of numbers from 0 to N-1
    • In Python, everything is an object, including functions and classes, and data type is a property of the object, not the variable
    • Python supports different data types such as integers, long integers, floating-point numbers, complex numbers, and string literals
    • String formatting in Python is similar to C's printf, using %s for converting objects to their string representation
    • Python has data collection types like lists (ordered, mutable), sets (unordered, no duplicates), and dictionaries (pairs of values)
    • Lists in Python are mutable and support various functions like append, insert, remove, pop, index, count, sort, and reverse for modifying content
    • Tuples in Python are immutable versions of lists, and sets are unordered collections with no duplicates
    • Python supports a wide range of data types and control structures for programming and data manipulation.
