String Slicing and Concatenation

String slicing and concatenation are essential techniques in Python for manipulating sequences of characters. By understanding how to slice and combine strings (concatenation), you can efficiently process text data, which is crucial in many programming contexts.

In the following video, Alex will demonstrate the practical applications of string slicing and concatenation. Watch closely, as these concepts are key to effective string manipulation:

String slicing allows you to extract substrings from a larger string by specifying the start and end indices. The syntax string[start:end] is used, where start is the index of the first character you want to include, and end is the index one past the last character you want to include. This technique is especially useful for breaking down and analyzing strings by parts.

Example Application

Let's take a closer look at how slicing works:


              1234567
            
fruit = "Strawberries"

# Slicing the string to get "Straw"
# Remember, the 'w' is indexed at 4 but if we want to include it in the slice, we need to go up to 5 
sliced_fruit = fruit[0:5]

print("Sliced part:", sliced_fruit)

Concatenation is the process of joining two or more strings end-to-end, forming a new string.

This is achieved using the + operator, making it straightforward to combine strings for various purposes, such as creating full sentences or generating formatted output.

Here's how you can concatenate strings to create a new string:


              12345678
            
# Concatenating strings
part1 = "Straw"
part2 = "berry"
new_word = part1 + part2  # "Strawberry"
print("Concatenated word:", new_word)

# If you want to separate the words with a space, you need to add " " between the two parts
print(part1 + " " + part2)  # "Straw berry"

Завдання

You are tasked with organizing grocery items into their respective aisles in a store. You're provided with a string listing various grocery items: "milk cheese bread apples oranges chicken".

Your job is to extract items that belong in the dairy and bakery categories, then use string slicing and concatenation to dynamically print a statement placing these items in the correct aisle.
