Answer: Python Puzzler #1644

The answer is B. The program prints:

UR
What the program prints
Checked by running the program for real.

Why?

word[1:3] is a slice: it starts at position 1 and stops before position 3. Positions count from 0.

Trace table

A trace table follows the program step by step. Here’s this one:

positionletter
0T
1U
2R
3T
4L
5E

The code again

word = "TURTLE"
print(word[1:3])

Try it: change one number in the program and predict the new output before you run it.
