Control structures are programming constructs that allow you to control the flow of execution in your Python code. There are three main types of control structures in Python: conditional statements, loops, and function calls.
Conditional statements, such as if-else statements, allow you to execute different blocks of code based on a certain condition. This can be useful for implementing branching logic or for checking input validity.
Loops, such as for and while loops, allow you to repeatedly execute a block of code. For loops are commonly used for iterating over a collection of objects, while loops are useful for running code until a certain condition is met.
Function calls are used to invoke a specific function or method, which can be defined in your own code or in an external library. Functions can take arguments and return values, which can be used to pass data between different parts of your program.
Together, these control structures provide powerful tools for controlling the flow of execution in your Python programs.
