Using for Loop To convert the entire list into one integer in Python: Create a list having integer-type elements. Declare and initialize a variable with 0; it will be used to hold the final integer value. Use the for loop to iterate over the list items. In each iteration: multiply the variable created in the […]

Using List slicing Use list slicing to get first n elements of List in Python. Here’s an example: [crayon-678d9ce429fb6797690803/] [crayon-678d9ce429fbb885765047/] In the above example, list slicing is used to get a list’s first n elements. As we can see, a list was defined as my_list with 6 elements [10, 20, 30, 40, 50, 60]. And […]
