Lecture
This lecture introduces control flow in Python programming, focusing on conditional statements and loops. The instructor begins by reviewing previous topics, including variable types and basic functions. The lecture then delves into control flow instructions, starting with the 'if' statement, which allows for conditional execution of code blocks based on boolean tests. The instructor explains the syntax and structure of 'if' statements, including the use of 'else' and 'elif' for multiple conditions. Following this, the lecture covers 'while' loops, which enable repeated execution of code as long as a specified condition remains true. The instructor provides examples of how to implement 'while' loops effectively, including the importance of updating loop variables to avoid infinite loops. Finally, the lecture introduces 'for' loops, which are used for iterating over a sequence of elements, and discusses the 'range' function for generating sequences of numbers. The session concludes with practical examples and exercises to reinforce the concepts learned.
