Type the program's output:
```
city = 'Beirut'
my_slice = city[4:5]
print(my_slice)
city = 'Dublin'
print(my_slice)
```

The program first assigns the string 'Beirut' to the variable city and extracts the character at index 4, which is 'u', and assigns it to my_slice . Then, it prints the value of my_slice . Next, it reassigns the string 'Dublin' to city , but my_slice remains unchanged. Finally, it prints the value of my_slice again, which is still 'u'. Therefore, the output of the program is:
u
u

Explanation

Understanding the Program We are asked to determine the output of a short Python program. The program first assigns the string 'Beirut' to the variable city . Then, it extracts a slice of this string from index 4 up to (but not including) index 5 and assigns it to the variable my_slice . The program then prints the value of my_slice . Next, the program reassigns the string 'Dublin' to the variable city . Finally, it prints the value of my_slice again. Since my_slice was assigned the slice of 'Beirut' and was never reassigned, it will print the same value again.

First Print Statement The first print(my_slice) statement will print the character at index 4 of the string 'Beirut'. In Python, string indices start at 0. So, the character at index 4 of 'Beirut' is 'u'.

Second Print Statement The second print(my_slice) statement will print the value of my_slice again. Since my_slice was assigned the slice of 'Beirut' and was never reassigned, it will print the same value again, which is 'u'.

Final Answer Therefore, the output of the program is:


u
u

Examples
String slicing is a fundamental concept in computer science and is used extensively in text processing, data analysis, and software development. For example, if you have a large text file and you want to extract specific information from it, you can use string slicing to isolate the relevant parts of the text. Imagine you are analyzing customer feedback from a survey. You can use string slicing to extract specific keywords or phrases from the feedback to identify common themes or sentiments. This allows you to automate the process of analyzing large amounts of text data and gain valuable insights.

The program creates a variable city with the string 'Beirut' and extracts the character at index 4, which is 'u'. It prints this character twice after changing the city to 'Dublin', but the extracted value remains unchanged. Therefore, the output will be 'u' on both lines printed.
