Study Notes
Python Programming Concepts
-
Comments: Comments in Python are ignored by the interpreter. Single-line comments begin with
#, and multi-line comments start with"""and end with""". -
Single-line Comments: In Python, a single-line comment begins with the
#symbol. -
Multi-line Comments: In Python, a multi-line comment starts and ends with three double quotes
" """. -
Data Types:
- Python has various data types
- Sequences are data types like strings, which hold multiple items.
- A group of characters arranged in a specific format.
Stringis a sequence of characters.- Numeric types include integers, floats, and complex numbers.
- A collection of valid characters that a programming languages can recognize.
-
Tokens: The smallest individual unit in a Python program, a token identifies components like identifiers, operators, and literals.
-
Identifiers: Identifiers in Python are names given to variables, functions, classes, etc. They consist of letters, numbers, and underscores, but cannot start with a number. Valid examples are
myVariable,FILE34, andF_L. An invalid example is34File. -
Keywords: Keywords are reserved words in Python, and they cannot be used as identifiers.
-
Literals: Literals represent fixed values in a program and can be numbers, strings, or booleans.
-
Operators: Operators are symbols used to perform operations on operands (values). They can be arithmetic, logical, or comparison operators.
-
Data Structures:
- Strings: Sequences of characters enclosed in quotation marks.
- Integers: Whole numbers (e.g., 10, -5).
- Floats: Numbers with decimal points (e.g., 3.14, -2.5).
- Dictionaries: Unordered collections of key-value pairs.
- Boolean: Represents True or False.
- Lists: Ordered collections of items.
- Tuples: Immutable ordered collections of items.
-
Input Function:
- The
input()function is used to take input from the user. - Input is treated as a string.
- If the user intends to input a numerical value, it will need further conversion, such as
int().
- The
Python Specifics
-
Input: The
input()function obtains input from the user. This input is treated as a string initially. -
Data Types: Python has different types of data:
- Integers, floats, booleans, strings, collections, etc.
-
Input Handling: If the user wants to input a number, the
input()function's output should be converted into the appropriate type (e.g.,intorfloat) using a conversion function.
