In this example, theindex()method is called onmy_listwith “banana” as the argument. The method returns the index of the first occurrence of “banana” in the list, which is 1. This means “banana” is the second element in the list (since list indices start at 0). 3. Usingcount(...
To find the indices of all occurrences of a given item in a list, you can useenumerate()method which works with iterable and returns an enumerate object. # String listcities=["bangalore","chennai","mangalore","chennai","delhi"]# Item to be founditem="chennai"index=-1fori, jinenumerate...

Out of 7 integers, the minimum element is 12 and its index position is 0. 3. Using for loop & index() to Get Min Index Here, we will iterate all elements in the list and compare whether the element is minimum to the current iterating value, If it is minimum, we will store this ...
You can do that usingnegative indexes. In the example above, we don’t know the length of the string, but we know that the word ‘text’ plus the exclamation sign take five indices, so we call negative five to access them. “Remember that Python starts counting indexes from 0 not 1....
Similarly, we can also use theenumerate()function, which returns the index and the value together. For example: l1=[1,5,1,8,9,15,6,2,1]pos=[ifori,xinenumerate(l1)ifx==1]print(pos) Output: [0, 2, 8] Use thenumpy.where()Function to Find the Indices of All the Occurrences of...
