f = open("data.txt", "rt")
lines = f.read()

for line in lines:
if line == 'how' or line == 'what' or line == 'where':
print(lines, "Yes")
else:
print(lines, "No")
f.close()
I am trying to read a file and look for sentences that have how, what, where, etc. Basically sentences that are a question. And printing the sentences along with a Yes or No accordingly.
Format of Input file:
how are you
it's 7 o'clock
where is your food
Format of Output file:
how are you Yes
it's 7 o'clock No
where is your food Yes
But my code is giving no output.
The line if line == 'how' or line == 'what' or line == 'where': suggests to me that you might want to use the logic of keyword any():
f = open("data.txt", "rt")
lines = f.readlines()
f.close()
with open('data_out.txt', 'w') as f:
for line in lines:
if any(question_word in line for question_word in ['how', 'what', 'where']):
output = '{} {}\n'.format(line.strip('\n'), "Yes")
print(output)
f.write(output)
else:
output = '{} {}\n'.format(line.strip('\n'), "No")
print(output)
f.write(output)
how are you Yes
it's 7 o'clock No
where is your food Yes

I am trying to make a parser for my text adventure. I used a text file called test.txt.
I keep getting IndexError: string index out of range. How can I fix this?
parser.py
def parse(file):
data = {}
with open(file, "r") as f:
lines = f.readlines()
f.close()
for line in lines:
line = line.strip()
if line[0] == "#":
name = line[1:]
name = name.replace("\n", "")
data[name] = {}
if line[0] == "-":
prop = line.split(":")
prop_name = prop[0].replace("-", "")
prop_name = prop_name.replace("\n", "")
prop_desc = prop[1][1:]
prop_desc = prop_desc.replace("\n", "")
data[name][prop_name] = prop_desc
return data
print(parse("test.txt"))
test.txt
#hello
-desc: Hello World! Lorem ipsum
-north: world
#world
-desc: World Hello! blah
-south: hello
You're stripping the newlines (line = line.strip()), so if a line is empty, there is just an empty string and line[0] is out of range.
You should test if the line is truthy:
if line and line[0] == "-":
Or, better, in the beginning of the loop, skip blank lines:
for line in lines:
if line == '\n':
continue
# rest of code
Since there is many "\n" in your text, you should ignore them in file reading.
try this:
with open(file, "r") as f:
lines = f.readline().splitlines()
f.close()
tocheck = 'abc:def:ghi'
with open("file1.txt", "r") as f:
lines = f.readlines()
with open("file1.txt", "w") as f:
for i, line in enumerate(lines):
a,b,c = line.split(':')
if f'{a}:{b}' == tocheck:
print('found it')
with open("file2.txt", 'a') as ban:
ban.write(f'\n{tocheck} was found')
else:
if i == len(lines)-1:
f.writelines(line.rstrip("\n"))
else:
f.writelines(line)
hey, so i have 2 text files, file1 and file2
My idea is to check file1 looking for a specific line and, if it is found, it will be written on file2 and removed from file1
until here, everything works, my problem is that the very last line of file1 can't end up having a new line at the end of it, but it still does and I have no idea on how to remove that \n from the last line only
I used this code to delete a word from a text file.
f = open('./test.txt','r')
a = ['word1','word2','word3']
lst = []
for line in f:
for word in a:
if word in line:
line = line.replace(word,'')
lst.append(line)
f.close()
f = open('./test.txt','w')
for line in lst:
f.write(line)
f.close()
But for some reason if the words have the same characters, all those characters get deleted. So for e.g
in my code:
def cancel():
global refID
f1=open("refID.txt","r")
line=f1.readline()
flag = 0
while flag==0:
refID=input("Enter the reference ID or type 'q' to quit: ")
for i in line.split(','):
if refID == i:
flag=1
if flag ==1:
print("reference ID found")
cancelsub()
elif (len(refID))<1:
print("Reference ID not found, please re-enter your reference ID\n")
cancel()
elif refID=="q":
flag=1
else:
print("reference ID not found\n")
menu()
def cancelsub():
global refIDarr, index
refIDarr=[]
index=0
f = open('flightbooking.csv')
csv_f = csv.reader(f)
for row in csv_f:
refIDarr.append(row[1])
for i in range (len(refIDarr)):
if refID==refIDarr[i]:
index=i
print(index)
while True:
proceed=input("You are about to cancel your flight booking, are you sure you would like to proceed? y/n?: ")
while proceed>"y" or proceed<"n" or (proceed>"n" and proceed<"y") :
proceed=input("Invalid entry. \nPlease enter y or n: ")
if proceed=="y":
Continue()
break
elif proceed=="n":
main_menu
break
exit
break
def Continue():
lines = list()
with open('flightbooking.csv', 'r') as readFile:
reader = csv.reader(readFile)
for row in reader:
lines.append(row)
for field in row:
if field ==refID:
lines.remove(row)
break
with open('flightbooking.csv', 'w') as writeFile:
writer = csv.writer(writeFile)
writer.writerows(lines)
f = open('refID.txt','r')
a=refIDarr[index]
print(a)
lst = []
for line in f:
for word in a:
if word in line:
line = line.replace(word,'')
lst.append(line)
print(lst)
f.close()
f = open('refID.txt','w')
for line in lst:
f.write(line)
f.close()
print("Booking successfully cancelled")
menu()
When the code is run, the refID variable has one word stored in it, and it should replace just that word with a blank space, but it takes that word for e.g 'AB123', finds all other words which might have an 'A' or a 'B' or the numbers, and replace all of them. How do I make it so it only deletes the word?
Text file before running code:
AD123,AB123
Expected Output in the text file:
AD123,
Output in text file:
D,
Edit: I have added the entire code, and maybe you can help now after seeing that the array is being appended to and then being used to delete from a text file.
here's my opinion.
refIDarr = ["AB123"]
a = refIDarr[0] => a = "AB123"
strings in python are iterable, so when you do for word in a, you're getting 5 loops where each word is actually a letter.
Something like the following is being executed.
if "A" in line:
line = line.replace("A","")
if "B" in line:
line = line.replace("B","")
if "1" in line:
line = line.replace("1","")
if "2" in line:
line = line.replace("2","")
if "3" in line:
line = line.replace("3","")
they correct way to do this is loop over refIDarr
for word in refIDarr:
line = line.replace(word,'')
NOTE: You don't need the if statement, since if the word is not in the line it will return the same line as it was.
"abc".replace("bananan", "") => "abc"
Here's a working example:
refIDarr = ["hello", "world", "lol"]
with open('mytext.txt', "r") as f:
data = f.readlines()
for word in refIDarr:
data = [line.replace(word, "") for line in data]
with open("mytext.txt", "w") as newf:
newf.writelines(data)
The problem is here:
a=refIDarr[index]
If refIDarr is a list of words, accessing specific index makes a be a word. Later, when you iterate over a (for word in a:), word becomes a letter and not a word as you expect, which causes eventually replacing characters of word instead the word itself in your file.
To avoid that, remove a=refIDarr[index] and change your loop to be:
for line in f:
for word in refIDarr:
if word in line:
line = line.replace(word,'')
In this spellchecking program i created i seem to be getting a error when trying to write to the output file.The file is created but instead of the output being written an error " <_io.TextIOWrapper name='f.txt' mode='w' encoding='cp1252'>name " is.
I've tried looking for solutions.

You're opening the file for reading, and then trying to write to it.
I have key words to be search in one file let say abc.txt and in another file I have my data, def.txt.
I want a code in python to find key words written in abc.txt, in def.txt and if present, print those line in a new file.
Thank you.
I tried writing a code but it didn't work.
following is the code I write.
f = open('/home/vivek/Documents/abc.txt')
f1 = open('output.txt', 'a')
f2 = open('/home/vivek/Documents/def.txt', 'r')
# doIHaveToCopyTheLine=False
for line in f.readlines():
if f2 in line:
f1.write(line)
f1.close()
f.close()
f2.close()
Load the keywords into a list then you can check the other file line-by-line, and write to outfile as you find keywords in the line.
with open('/path/to/keywords.txt') as f:
keywords = set(line.strip() for line in f) # assuming words are separated by line
with open('/path/to/search_me.txt') as f, open('/path/to/outfile.txt', 'w') as outfile:
for line in f:
if any(kw in line for kw in keywords):
outfile.write(line)
You should record all the words in abc.txt use a set and then search them in def.txt
word_set = set()
with open('/home/vivek/Documents/abc.txt') as f:
for line in f:
word_set.add(line.strip())
f1 = open('output.txt', 'a')
with open('/home/vivek/Documents/def.txt') as f:
for line in f:
find = False
for word in word_set:
if word in line:
find = True
break
if find:
f1.write(line)
f1.close()
You can try this code:
with open("keyword.txt", "r") as keyword_file:
keywords = keyword_file.read().strip()
keywords = keywords.split()
with open("data.txt", "r") as data_file, open("output.txt", "w") as output_file:
for line in data_file.readlines():
line = line.strip()
for word in keywords:
if line.find(word) != -1:
print line
output_file.writelines(line + '\n')
break
In addition to sytech's answer you may try this:
with open('def.txt') as kw_obj, open('abc.txt') as in_obj:
keywords = set(kw_obj.read().split())
in_lines = in_obj.readlines()
match_lines = [line for keyword in keywords for line in in_lines if keyword in line]
if match_lines:
with open('out.txt', 'w') as out:
out.write(''.join(match_lines))
