Write a python program to find string,charecters,words and sentence in a text file contains 5000 lines of sentence.

Answer 1

Regex will manage it nicely.
You can check the code now, I updated it. You just need to assign re.findall to a variable. This will be a list of sentences, so you can check its length to see the number of sentences found.

Answer 2

@RUDRESH
Here's how. Either by str.split() or by using regex module. Notice the difference in precision.

Answer 3

You will need regex for this. Check out 're' library and its documentation, it's really powerful:
https://docs.python.org/3/library/re.html

Answer 4

Depends what you define as 'sentence'. Any character plus whitespaces string between two dots? Will that be enough for a definition?

Answer 6

a is just a variable to which I assigned a docstring. You can open() a file and .read() it, in order to look for sentences in it.

Answer 7

@yuri Yes, it might work better for matching, indeed. Won't dispose of the line breaks before the beginnings of the sentences though :)

Answer 8

@Kuba Siekierzynski
Works fine. ☺

Answer 9

fname = input("Enter file name")
num_words = 0
chars = 0

with open(fname,'r')as f:
for line in f:
words = lines split()
num_words +=len(words)
chars = chars+len(line)

print (num_words)
print (chars)

Answer 11

there are several typos, indentations, break operator missing.

import os.path

text = """Hi , Fisrt line
fdsgd fgfdkg sdg sdf sdfg -> voidvoid <- sdf kkds
dfsdf
sdf sdf df.
fsdfsd sfd sgojhoptrye -> void <- y ytryrthdfdfs re re ewr gfdsfg r
rtert . F rtret ret dsfgedr
"""

my_file = 'text2.txt'
my_string ='void'
infile = open(my_file,"w")
infile.write (text)
infile.close()

infile = open(my_file,"r")
numlines =0
found =0

for line in infile:
print (line)
numlines+=1
while 1:
str_found_at = line.find(my_string)
if str_found_at == -1:
break
else:
found+=1
line = line[str_found_at+len(my_string):]
infile.close()
print ("%s was found %i times in %i lines" %(my_string,found,numlines))
