[SOLVED] Efficient way of reading word count from a file and calculating average per sentence

Efficient way of reading word count from a file and calculating average per sentence

I need to write a python code that reads the contents of a text file(file.txt) and calculate the average number of words per sentence.(Assuming the file contains a number of sentences only one per line.)

i did the coding and i need to know whether it can be more efficient in another way. Million thanks in advance. here is mine :

# This program reads contents of a .txt file and calulate
# the average number of words per sentence .

line_count=0
# open the file.txt for reading
content_file=open('file.txt','r')

# calculate the word count of the file
content=content_file.read()

words= content.split()

word_count=len(words)

# calculate the line count
for line in open('file.txt'):

    line_count+=1

content_file.close()

# calculate the average words per line

average_words=word_count/line_count

# Display the result

print('The average word count per sentence is', int(average_words))

Solution

No need to iterate the file twice. Just update the counts while you go through the lines::

lc, wc = 0, 0
with open('file.txt','r') as f:
    for line in f:
        lc += 1
        wc += len(line.strip().split())

avg = wc / lc
