How can I fix this code segment to run AP CSP pseudocode?-CodePudding

I'm attending an AP CSP class and I'm trying to turn this pseudocode:

into runnable Python code.

This is what I've coded:

words = ["song", "book", "video", "book"]
index = 1
n = len(words)

for i in range (n):
  if words[index] == "book":
    words.insert(index, "read")
    index = index   1
  else:
    index = index   1
    
print(words)

And this is the intended result:

["song", "read", "book", "video", "read", "book"]

But after running the code segment I coded, this is what I got:

['song', 'read', 'read', 'read', 'read', 'book', 'video', 'book']

Can anyone help me?

CodePudding user response：

You should delete the "else" sentence, and pull the indentation of the below line.

like this

words = ["song", "book", "video", "book"]
index = 1
n = len(words)

for i in range (n):
  if words[index] == "book":
    words.insert(index, "read")
    index = index   1
  index = index   1

print(words)
