The answer is C. The program prints:
4
Why?
count goes through the string and counts how many times ‘s’ appears.
Trace table
A trace table follows the program step by step. Here’s this one:
| letter | matches? |
|---|---|
| m | |
| i | |
| s | yes |
| s | yes |
| i | |
| s | yes |
| s | yes |
| i | |
| p | |
| p | |
| i |
The code again
word = "mississippi"
print(word.count("s"))Try it: change one number in the program and predict the new output before you run it.
