Strings In Python — Part 1 MCQs with Explanations

Understanding String Slicing in Python In Python, strings are sequences of characters. We can access parts of a string using slicing . String slicing uses square brackets `[]` and a colon `:` to specify a range of characters. The format is `string[start:end]`. The `start` index indicates where to begin (inclusive), and the `end` index indicates where to stop (exclusive). Let's break down the code: string = "Python" This line assigns the string "Python" to the variable string . print(string[1:4]) This line uses slicing to extract a portion of the string. Let's analyze the indices: - 1 (start index): This means we start at the second character (remember, Python uses zero-based indexing, so the first character is at index 0). - 4 (end index): This means we stop just before the fourth character. Therefore, string[1:4] will extract characters from index 1 ( 'y' ) up to, but not including, index 4. The Result: The characters extracted are "yth". Therefore, the correct answer is Option A: yth
