Thanks for the detailed explanation. I always struggle to solve any programming challenges. Listening to your explanations really helps with the thought process and very few people do that.

F-strings are even better than .format(). I'd like to see an update to this lesson with f-strings.

Hello Abhishek bhaiya.
I hope you are doing well. I am Prabhav. I have been going through your 30-days-of-ml series but unfortunately i missed out on the registration for the competition on August 2. I wanted to know if there is a way I can still solve the problems and check my submissions?

Good day, Sir Abhishek! I am confused in the last part of the lecture on item 3. Why do we make these lines of code?
indices = word_search(doc_list, keyword)
keyword_locations[keyword] = indices

Second last day? Wont you cover all 30 days?

My output is giving error : 'list' object has no attribute 'lower'
How to solve this error... please reply..

In the 2nd question,
I tried to write this code and checked its output:

doc_list = ["The Learn Python Challenge Casino.", "They bought a car", "Casinoville"]
for doc in doc_list:
tokens = doc.split()
print(tokens)

and the result shown was only ['Casinoville'], why is it so, instead of splitting all the words by spaces?

alvinbong

for 2nd question: I did this code

indices = []
for i, doc in enumerate(doc_list):
tokens = doc.split()
for token in tokens:
word = [token.strip('., ').lower()]
if keyword.lower() in word:
indices.append(i)
return indices

but I got the error of Incorrect: Expected return value of [1] given doc_list=['The Learn Python Challenge Casino', 'They bought a car, and a horse', 'Casinoville?'], keyword='car', but got [] instead.

'str'.join() split the string not in form of words but letters.. any thought please:

k = 'hallo people'
k.split()
a = '!'.join([word for word in k])
print(a)

=>:
h!a!l!l!o! !p!e!o!p!l!e

what did I do wrong?

lifelonglearning

key_indice = {}
for keyword in keywords:
index = word_search(doc_list, keyword)
key_indice[keyword]= index
return key_indice

Incorrect: Expected return value of {'casino': [0], 'ear': [], 'bought': [1]} given doc_list=['The Learn Python Challenge Casino', 'They bought a car', 'Casinoville?'], keywords=['casino', 'ear', 'bought'], but got {'casino': [0], 'ear': [], 'bought': []} instead
