so i got this error while trying to run the following code , i thought first that it might be that i didn't correctly convert the string to the list , but it seems to me that's it's correct or i'm i wrong ? , thanks.
here's on what i'm trying to run the Code:
u0 +++$+++ u2 +++$+++ m0 +++$+++ ['L194', 'L195', 'L196', 'L197']
u0 +++$+++ u2 +++$+++ m0 +++$+++ ['L198', 'L199']
u0 +++$+++ u2 +++$+++ m0 +++$+++ ['L200', 'L201', 'L202', 'L203']
u0 +++$+++ u2 +++$+++ m0 +++$+++ ['L204', 'L205', 'L206']
u0 +++$+++ u2 +++$+++ m0 +++$+++ ['L207', 'L208']
conversations_fields = ['Character_one_ID' , 'Character_two_ID' , 'Movie_ID' , 'utteranceIDs']
conversations = []
with open("./cornell movie-dialogs corpus/movie_conversations.txt", 'r', encoding='iso-8859-1') as f:
for line in f:
values = line.split(" +++$+++ ")
# Extract fields
convObj = {}
for i, field in enumerate(conversations_fields):
convObj[field] = values[i]
# Convert string to list (convObj["utteranceIDs"] == "['L598485', 'L598486', ...]")
lineIds = eval(convObj["utteranceIDs"])
# Reassemble lines
convObj['lines'] = []
for lineId in lineIds:
convObj['lines'].append(lines[lineId]
conversations.append(convObj)
TypeError Traceback (most recent call last)
<ipython-input-34-d7002161f69c> in <module>()
13 convObj['lines'] = []
14 for lineId in lineIds:
---> 15 convObj['lines'].append(lines[lineId])
16 conversations.append(convObj)
TypeError: list indices must be integers or slices, not str
lineIds = convObj['utteranceIDs']
is filled with the eval
of "['L194', 'L195', 'L196', 'L197']"
- see Why is using 'eval' a bad practice? :
lineIds = eval(convObj["utteranceIDs"])
lineIds
is a list of strings, lineID
is also a string ( "L194"
then "L195"
etc...) - you can not use it to index into lines
:
for lineId in lineIds: convObj['lines'].append(lines[lineId]) # you also missed a ) here
