How to use the Python return statement in your functions.

#Python shortcat for returning greater item code#

Using the return statement effectively is a core skill if you want to code custom functions that are Pythonic and robust. You can use them to perform further computation in your programs. These objects are known as the function’s return value. You can use the return statement to make your functions send Python objects back to the caller code. The Python return statement is a key component of functions and methods. Watch it together with the written tutorial to deepen your understanding: Using the Python return Statement Effectively In this Python Tutorial, we learned how to find the index of an element/item in a list, with the help of well detailed examples.Watch Now This tutorial has a related video course created by the Real Python team. except ValueError: block catches this Error and the corresponding block is executed. Therefore, mylist.index(item) throws ValueError. The item, whose index we are trying to find, is not present in the list. Print('The index of', item, 'in the list is:', index) In the following example, we shall learn how to use try-except statement to handle this ValueError. Output Traceback (most recent call last):Īs index() can throw ValueError, use Python Try-Except while using index(). In the following program, we have taken a list and shall try to find the index of an element that is not present in the list. If the element that we are searching in the List is not present, you will get a ValueError with the message item is not in list. Example 4: Find Index of Item in List – Item not present When the item matches the argument, the function returns that index. The function scans the list from starting. Let us understand how index() method works. The element 52 is present two times, but only the index of first occurrence is returned by index() method.

In such cases, only the index of first occurrence of specified element in the list is returned. only this part of the list is consideredĠ 1 2 3 4 => 4 is returned by index() Example 3: Find Index of Item – Item has multiple occurrences in ListĪ Python List can contain multiple occurrences of an element. index() function considers only those elements in the list starting from start index, till end position in mylist.Įxplanation mylist =

Using index() method we will find the index of item 8 in the list. In the following example, we have taken a List with numbers. The element is present at 3rd position, so mylist.index() function returned 2.Įxample 2: Find Index of Item in List – start, end

Print('The index of', item, 'in the list is:', index) Run We shall look into examples, where we go through each of these scenarios in detail. If you provide a value for start, then end is optional. You can also provide start and end positions of the List, where the search has to happen in the list.įollowing is the syntax of index() function with start and end positions. The index() method returns an integer that represents the index of first match of specified element in the List. To find index of the first occurrence of an element in a given Python List, you can use index() method of List class with the element passed as argument.
