Finding the index of an item in a list: In this tutorial, we will learn how to find the index of a given item in a Python list. Learn with the help of examples.
To find the index of an element in the list in Python, we can also use theforloop method. The code is: consonants=["b","f","g","h","j","k"]check="j"position=-1foriinrange(len(consonants)):ifconsonants[i]==check:position=ibreakifposition>-1:print("Element's Index in the ...
