So I'm currently trying to write some code that opens and reads a text file. The text file contains a short paragraph. Within the paragraph, there are some words with brackets around them, which could look like: "the boy [past_tense_verb] into the wall." I am trying to write code that looks for the brackets in the text file, and then displays to the user the words in the text file, for the user to then write some input that will replace the bracketed words. This is the code I have so far:
f = open('madlib.txt', 'r')
for line in f:
start = line.find('[')+1
end = line.find(']')+1
word = line[start:end+1]
inputword = input('Enter a ' + word + ': ')
print(line[:start] + inputword + line[end:])
Any help is greatly appreciated - thanks!
import re
with open('madlib.txt', 'r') as f:
data = f.read()
words_to_replace = re.findall(r"\[(\w+)\]", data)
replace_with = []
for idx, i in enumerate(words_to_replace):
print(f"Type here replace \033[1;31m{i}\033[1;m with:", end =" ")
a = input()
replace_with.append(a)
for idx, i in enumerate(replace_with):
data = data.replace(words_to_replace[idx], i)
with open('newmadlib.txt', 'w') as f:
f.write(data)

I want to open text file and slice words based on blank spaces, but cut by \n. Why does it work like this? Is the problem in the text file or that my code is wrong?
def process(w):
output =""
for ch in w:
if ch.isalpha() :
output += ch
return output.lower()
words = set()
fname = input("file name: ")
file = open(fname, "r")
for line in file:
lineWords = line.split()
for word in lineWords:
words.add(process(lineWords))
print("Number of words used =", len(words))
print(words)
Text file:
Result:
I'm working on a minor content analysis program that I was hoping that I could have running through several pdf-files and return the sum of frequencies that some specific words are mentioned in the text. The words that are searched for are specified in a separate text file (list.txt) and can be altered. The program runs just fine through files with .txt format, but the result is completely different when running the program on a .pdf file. To illustrate, the test text that I have the program running trhough is the following:
"Hello
This is a product development notice
We’re working with innovative measures
A nice Innovation
The world that we live in is innovative
We are currently working on a new process
And in the fall, you will experience our new product development introduction"
The list of words grouped in categories are the following (marked in .txt file with ">>"):
innovation: innovat
product: Product, development, introduction
organization: Process
The output from running the code with a .txt file is the following:
Whereas the ouput from running it with a .pdf is the following:
As you can see, my issue is pertaining to the splitting of the words, where in the .pdf output i can have a string like "world" be split into 'w','o','rld'. I have tried to search for why this happens tirelessly, without success. As I am rather new to Python programming, I would appreciate any answe or direction to where I can fin and answer to why this happens, should you know any source.
Thanks
The code for the .txt is as follows:
import string, re, os
import PyPDF2
dictfile = open('list.txt')
lines = dictfile.readlines()
dictfile.close()
dic = {}
scores = {}
i = 2011
while i < 2012:
f = 'annual_report_' + str(i) +'.txt'
textfile = open(f)
text = textfile.read().split() # lowercase the text
print (text)
textfile.close()
i = i + 1
# a default category for simple word lists
current_category = "Default"
scores[current_category] = 0
# import the dictionary
for line in lines:
if line[0:2] == '>>':
current_category = line[2:].strip()
scores[current_category] = 0
else:
line = line.strip()
if len(line) > 0:
pattern = re.compile(line, re.IGNORECASE)
dic[pattern] = current_category
# examine the text
for token in text:
for pattern in dic.keys():
if pattern.match( token ):
categ = dic[pattern]
scores[categ] = scores[categ] + 1
print (os.path.basename(f))
for key in scores.keys():
print (key, ":", scores[key])
While the code for the .pdf is as follows:
import string, re, os
import PyPDF2
dictfile = open('list.txt')
lines = dictfile.readlines()
dictfile.close()
dic = {}
scores = {}
i = 2011
while i < 2012:
f = 'annual_report_' + str(i) +'.pdf'
textfile = open(f, 'rb')
text = PyPDF2.PdfFileReader(textfile)# lowercase the text
for pageNum in range(0, text.numPages):
texts = text.getPage(pageNum)
textfile = texts.extractText().split()
print (textfile)
i = i + 1
# a default category for simple word lists
current_category = "Default"
scores[current_category] = 0
# import the dictionary
for line in lines:
if line[0:2] == '>>':
current_category = line[2:].strip()
scores[current_category] = 0
else:
line = line.strip()
if len(line) > 0:
pattern = re.compile(line, re.IGNORECASE)
dic[pattern] = current_category
# examine the text
for token in textfile:
for pattern in dic.keys():
if pattern.match( token ):
categ = dic[pattern]
scores[categ] = scores[categ] + 1
print (os.path.basename(f))
for key in scores.keys():
print (key, ":", scores[key])
def match_text(raw_data_file, concentration):
file = open(raw_data_file, 'r')
lines = ""
print("Testing")
for num, line in enumerate(file.readlines(), 0):
w = ' WITH A CONCENTRATION IN ' + concentration
if re.search(w, line):
for i in range(0, 6):
lines += linecache.getline(raw_data_file, num+1)
try:
write(lines, "lines.txt")
print("Lines Data Created...")
except:
print("Could not print Line Data")
else:
print("Didn't Work")
I am trying to open a .txt file and search for a specific string.
If you are simply trying to write all of the lines that hold your string to a file, this will do.
def match_text(raw_data_file, concentration):
look_for = ' WITH A CONCENTRATION IN ' + concentration
with open(raw_data_file) as fin, open('lines.txt', 'w') as fout:
fout.writelines(line for line in fin if look_for in line)
Fixed my own issue. The following works to find a specific line and get the lines following the matched line.
def match_text(raw_data_file, match_this_text):
w = match_this_text
lines = ""
with open(raw_data_file, 'r') as inF:
for line in inF:
if w in line:
lines += line //Will add the matched text to the lines string
for i in range(0, however_many_lines_after_matched_text):
lines += next(inF)
//do something with 'lines', which is final multiline text
This will return multiple lines plus the matched string that the user wants. I apologize if the question was confusing.
I'm trying to modify a txt file. The file is a movie script in the format:
BEN We’ve discussed this before.
LUKE I can be a Jedi. I’m ready.
I'd like insert a new line after the character:
BEN
We’ve discussed this before.
LUKE
I can be a Jedi. I’m ready.
How do I do this in python? I currently have:
def modify_file(file_name):
fh=fileinput.input(file_name,inplace=True)
for line in fh:
split_line = line.split()
if(len(split_line)>0):
first_word = split_line[0]
replacement = first_word+'\n'
first_word=first_word.replace(first_word,replacement)
sys.stdout.write(first_word)
fh.close()
As suggested in one of the comments, this can be done using split and isupper. An example is provided below:
source_path = 'source_path.txt'
f = open(source_path)
lines = f.readlines()
f.close()
temp = ''
for line in lines:
words = line.split(' ')
if words[0].isupper():
temp += words[0] + '\n' + ' '.join(words[1:])
else:
temp += line
f = open(source_path, 'w')
f.write(temp)
f.close()
There are multiple problems with your code.
import fileinput
def modify_file(file_name):
fh=fileinput.input("output.txt",inplace=True)
for line in fh:
split_line = line.split()
if(len(split_line)>0):
x=split_line[0]+"\n"+" ".join(split_line[1:])+"\n"
sys.stdout.write(x)
fh.close() #==>this cannot be in the if loop.It has to be at the outer for level
I am trying to write a program that opens a text document and replaces all four letter words with **. I have been messing around with this program for multiple hours now. I can not seem to get anywhere. I was hoping someone would be able to help me out with this one. Here is what I have so far. Help is greatly appreciated!
def censor():
filename = input("Enter name of file: ")
file = open(filename, 'r')
file1 = open(filename, 'w')
for element in file:
words = element.split()
if len(words) == 4:
file1 = element.replace(words, "xxxx")
alist.append(bob)
print (file)
file.close()
here is revised verison, i don't know if this is much better
def censor():
filename = input("Enter name of file: ")
file = open(filename, 'r')
file1 = open(filename, 'w')
i = 0
for element in file:
words = element.split()
for i in range(len(words)):
if len(words[i]) == 4:
file1 = element.replace(i, "xxxx")
i = i+1
file.close()
for element in file:
words = element.split()
for word in words:
if len(word) == 4:
etc etc
Here's why:
say the first line in your file is 'hello, my name is john'
then for the first iteration of the loop: element = 'hello, my name is john'
and words = ['hello,','my','name','is','john']
You need to check what is inside each word thus for word in words
Also it might be worth noting that in your current method you do not pay any attention to punctuation. Note the first word in words above...
To get rid of punctuation rather say:
import string
blah blah blah ...
for word in words:
cleaned_word = word.strip(string.punctuation)
if len(cleaned_word) == 4:
etc etc
Here is a hint: len(words) returns the number of words on the current line, not the length of any particular word. You need to add code that would look at every word on your line and decide whether it needs to be replaced.
Also, if the file is more complicated than a simple list of words (for example, if it contains punctuation characters that need to be preserved), it might be worth using a regular expression to do the job.
It can be something like this:
def censor():
filename = input("Enter name of file: ")
with open(filename, 'r') as f:
lines = f.readlines()
newLines = []
for line in lines:
words = line.split()
for i, word in enumerate(words):
if len(word) == 4:
words[i] == '**'
newLines.append(' '.join(words))
with open(filename, 'w') as f:
for line in newLines:
f.write(line + '\n')
def censor(filename):
"""Takes a file and writes it into file censored.txt with every 4-letterword replaced by xxxx"""
infile = open(filename)
content = infile.read()
infile.close()
outfile = open('censored.txt', 'w')
table = content.maketrans('.,;:!?', ' ')
noPunc = content.translate(table) #replace all punctuation marks with blanks, so they won't tie two words together
wordList = noPunc.split(' ')
for word in wordList:
if '\n' in word:
count = word.count('\n')
wordLen = len(word)-count
else:
wordLen = len(word)
if wordLen == 4:
censoredWord = word.replace(word, 'xxxx ')
outfile.write(censoredWord)
else:
outfile.write(word + ' ')
outfile.close()
