If the processing logic require so, the sequential flow of execution can be altered in two way: - Conditional execution: a block of one or more statements will be executed if a certain expression is true - Repetitive execution: a block of one or more statements will be repetitively executed as long as a certain expression is true. In this section, we will cover _if_, _else_, _elif_ statements. The comparison and logical operators we learned in previous sections will be useful here. ### If Condition -In python and other programming languages the key word _if_ we use to check if a condition is true and to execute the block code.
