Question

Consider the following procedures for string manipulation.

Assume that the string oldString contains at least 4 characters. A programmer is writing a code segment that is intended to remove the first two characters and the last two characters from oldString and assign the result to newString.
For example, if oldString contains "student", then newString should contain "ude".
Which of the following code segments can be used to assign the intended string to newString ?
Select two answers.

Answer 1

The intended code segments for removing the first two and last two characters from a string in Python are 'newString = oldString[2:-2]' and 'newString = oldString[2:len(oldString)-2]'.

Step-by-step explanation:

The intended code segment for removing the first two characters and the last two characters from a string is:

newString = oldString[2:-2]

This code uses string slicing to extract a portion of the original string starting from the third character and ending before the third-last character.

Another option is to use concatenation:

newString = oldString[2:len(oldString)-2]

This code concatenates two slices: one from the third character to the end of the string, and another from the start of the string to the third-last character.
