Best way to avoid multiple if statements in python

#python #bestpractic

In general scenario, if you want to check multiple conditions of a simple operation like:

def getFoodPrice(itemName: str) -> float: if itemName == "Idli": return 10 if itemName == "Rice": return 100 else: raise Exception("Item not found")
Enter fullscreen mode Exit fullscreen mode

In these kinds of scenario we can use Dict object to perform fast and it is very scalable

itemPrice: Dict[str, float] = { "idli": 10, "rice": 100 } def getFoodPrice(itemName: str) -> float: try: return itemPrice[itemName.lower()] except KeyError: raise Exception("Item not found")
Enter fullscreen mode Exit fullscreen mode

This will reduce the lines of code and improve the scalability. If any new items needs to be added, we can update the dict object not the code.
