If-else
If-else is a conditional statement used in programming to execute different actions based on whether a certain condition is true or false. In data science and artificial intelligence, if-else statements are commonly used in decision-making processes. For example, in a machine learning model, if-else statements can be used to determine which features are most important in predicting a certain outcome. If-else statements can also be used in data cleaning and preprocessing to handle missing or invalid data. In addition, if-else statements can be used in natural language processing to determine the sentiment of a text based on certain keywords or phrases.
