Control Flow We often need to run specific code for certain conditions or we must run a code snippet many times. Toward we have this behavors we need of structures of control flow. Basically these structures are divided into conditional and repeating structures. Conditional structures allow select code snippets for specific conditions while Loop structures allow the execution of code snippets many times. Conditional structures in Python The logical conditionals usein Python are: Equals: a == b Not Equals: a != b Less than: a < b Less than or equal to: a <= b Greater than: a > b Greater than or equal to: a >= b These conditions are fundamental to statement logical and loops Simple if-statement. In this example were declared two variables: a and b. In the if-statement was defined the condition b > a. As b is equal the five and a is equal to three the message "b greater than a" will show to the user. Code Block In Python, The code block is defined through
