Consider the string new_string = ‘code development in python’ which statement will return ‘velop’ as a substring

Consider the string new_string = ‘code development in python’ which statement will return ‘velop’ as a substring

The correct answer and explanation is:

The correct statement to extract the substring ‘velop’ from the string new_string = 'code development in python' is:

new_string[5:10]

Explanation:

In Python, strings are indexed using zero-based indexing, meaning the first character has an index of 0. To extract a specific part of the string, you can use slicing, which follows the syntax string[start:end]. Here’s a breakdown of the slicing:

1. Indexing the String:
   • The string new_string is 'code development in python'.
   • The characters of this string, indexed from 0, are as follows: 'c' (index 0), 'o' (index 1), 'd' (index 2), 'e' (index 3), ' ' (index 4), 'd' (index 5), 'e' (index 6), 'v' (index 7), 'e' (index 8), 'l' (index 9), 'o' (index 10), 'p' (index 11), 'm' (index 12), 'e' (index 13), 'n' (index 14), 't' (index 15), ' ' (index 16), 'i' (index 17), 'n' (index 18), ' ' (index 19), 'p' (index 20), 'y' (index 21), 't' (index 22), 'h' (index 23), 'o' (index 24), 'n' (index 25).
2. Extracting ‘velop’:
   • The word “velop” starts at index 5 ('d') and ends at index 10 ('o'), which includes indices 5, 6, 7, 8, and 9.
   • The syntax new_string[5:10] means “start at index 5 and slice up to (but not including) index 10.”
3. Slicing in Python:
   • The slice new_string[5:10] will extract characters from index 5 to index 9, resulting in the substring 'velop'.

Thus, the statement new_string[5:10] will return the substring 'velop' from the string new_string.
