The answer is B. The program prints:
2
This answer was checked by running the program for real.
Why?
count goes through the string and counts how many times ‘r’ appears.
Trace table
A trace table follows the program step by step. Here’s this one:
| letter | matches? |
|---|---|
| p | |
| r | yes |
| o | |
| g | |
| r | yes |
| a | |
| m | |
| m | |
| i | |
| n | |
| g |
The code again
word = "programming"
print(word.count("r"))Try it: change one number in the program and predict the new output before you run it.
