The Complete Python Course - Negative Indexing to Access Substrings

The video tutorial explains negative indexing in strings, which allows slicing from the end. It demonstrates creating a string and using negative indices to extract substrings. Examples show how to specify start and end indices using negative numbers, illustrating how to retrieve specific parts of a string.

What is the primary purpose of negative indexing in strings?

• To start slicing from the beginning of the string

• To start slicing from the end of the string

• To convert strings to uppercase

• To find the length of the string

In the example given, what does the range '-4 to -2' represent?

• A specific substring from the end

• The last four characters of the string

• The middle section of the string

• The start and end of the string

How does negative indexing help in string manipulation?

• It allows for easy access to the start of the string

• It simplifies accessing elements from the end of the string

• It automatically sorts the string

• It changes the string to lowercase

What happens when you use the range '-6 to -5' in negative indexing?

• It selects the first six characters

• It selects a substring from the start

• It selects a substring from the end

• It selects the entire string

Which of the following is true about negative indexing?

• It is used to reverse the string

• It is used to access elements from the end of the string

• It is used to access elements from the start of the string

• It can only be used with numbers
