Description

This course will introduce you to the basics of programming and algorithms. You will implement the different key stages of building a computer program using the Python language. You will discover lexicon and syntax elements, tools, code organization and tests.

Who is this training for ?

For whom ?

Anyone who needs to learn to program.

Prerequisites

No special knowledge.

Training objectives

Structuring programs according to an algorithm Master the lexicon and syntax elements of a language to write a program Compile and run a program Debug and test a program

Training program

• A program
  • What is a program?
  • What is a language? The different paradigms.
  • What is 'an algorithm? The pseudo-language.
  • Compilers. Executables.
  • Presentation of a first algorithm in pseudo-language.
• Genesis of a first program
  • Writing a program: syntax and instructions.
  • Compilation and execution of the program.
  • What is a library? Its role, its usage.
  • Exercise: Writing, compiling and running a first Python program.
• Programming rules
  • Naming convention. Syntactic convention.
  • Use of comments. Why comment on developments?
  • Improve the readability of programs: code indentation, code splitting. ..
• The variables
  • What is a variable?
  • Primitive types: integers, strings, real numbers, others.
  • Declaration, definition and initialization of a variable. Constants.
  • Input, display, assignment, type conversion.
  • Organize your data in the form of tables.
  • Practical work
• Operators and expressions
  • The different operators (addition, equality...).
  • Combination of operators.
  • Boolean expression.
  • Exercise
• Control structures
  • Alternative selections (if, if-then-else...).
  • Instruction blocks (concept of Start...End).
  • Iterative loops (while-repeat, repeat-until, for-from-to).
  • Nesting instructions.
  • Exercise
• Procedures and functions
  • Definitions: procedure, function. Interest.
  • Passing parameters.
  • The return code of a function. Calling functions.
• Maintenance, debugging and testing of programs
  • Know how to interpret the different error messages.
  • Use a debugger: execution of a program step by step, breakpoints, inspect variables.
  • Using a debugger: executing a program step by step, breakpoints, inspecting variables.
  • Practical work
