To extract the substring "read" from the string "I'm ready", let's carefully analyze how string slicing works.
The string indexing in Python starts at 0, so the indices for the string "I'm ready" are as follows:
[tex]\[
\begin{array}{c|c|c|c|c|c|c|c|c}
\text{Character} & I & ' & m & \space & r & e & a & d & y \\
\hline
\text{Index} & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\
\end{array}
\][/tex]
To extract the characters from "read":
- "r" is at index 4,
- "e" is at index 5,
- "a" is at index 6, and
- "d" is at index 7.
So, in order to get "read", we need a slice that starts at index 4 and ends just before index 8. The slicing notation in Python for this substring is [4:8].
Thus, the correct way to complete the print function to return "read" is:
[tex]\[
\text{print(my_string[4:8])}
\][/tex]
Hence, the correct option from the given choices is:
[tex]\[
\text{my_string [4:8]}
\][/tex]
