Here is the solution

for line in f:
words = line.strip().split() # Remove trailing newline and split into words
word_count = len(words)
f_out.write(line.strip() + " wordcount " + str(word_count) + "\n") # Append word count and newline

f.close()
f_out.close()

Great explanation. Would you be able to create a tutorial on reading values in a text file using splitlines, previous_lines nested in a for loop. Basically how to take field name & respective value from a text file and output them into a pandas dataframe.

Hi Sir,
Love your content as always...great video..
I have few questions regarding the example you have taken in this video:
If expand the conversation in the example taken
Using text file handling and string manipulation in python
1) How can I find the number of unique speaker and list of all speaker present in file and also want separate file for each speaker.
2) I want to find the list of all unique words spoken by each unique speaker in new line and want to save these words in respective speaker's file .
3) how to remove all punctuations.

If I will get the answer it will be great help.

number = k.readlines()
number = [x.strip() for x in number]
count =0
for i in number:
if i.__contains__(str(num)):
count = count +1
print(count)
