Python Basics Quiz

Basic Syntax

• Indentation: uses spaces (not tabs) to define block-level structure
• Comments: start with # and extend to the end of the line
• Print function: print() is used to output text to the screen

Data Types

• Integers: whole numbers, e.g. 1, 2, 3, etc.
• Floats: decimal numbers, e.g. 3.14, -0.5, etc.
• Strings: sequences of characters, e.g. "hello", 'hello', etc.
  • String concatenation: + operator, e.g. "hello " + "world"
  • String formatting: % operator, e.g. "hello %s" % "world"
• Boolean: true or false values
• Lists: ordered collections of items, e.g. [1, 2, 3], ["a", "b", "c"]
  • Indexing: access individual elements with [], e.g. my_list[0]
  • Slicing: access a subset of elements with [], e.g. my_list[1:3]

Control Structures

• If-else statements: conditional execution of code
  • Syntax: if condition : code elif condition : code else: code
• For loops: iterate over a sequence
  • Syntax: for variable in sequence : code
• While loops: repeat code while a condition is true
  • Syntax: while condition : code

Functions

• Defining functions: create reusable code blocks
  • Syntax: def function_name (parameters): code
• Function calls: execute a function with arguments
  • Syntax: function_name(arguments)

Modules

• Importing modules: load external libraries
  • Syntax: import module_name
• Module functions: access functions from a module
  • Syntax: module_name.function_name(arguments)
