cloze solver not working

I have been using python for some time, I have a file that is the english alphabet with each word on separate lines, and I have ironed out all the errors, but it doesn't type anything anymore. I'm open to any help, and improvements to the code, provided you explain how it works. If you are looking for the file it is here
f = open("C:\\my folders\\brit-a-z.txt", 'r')
print("Type in your cloze word like this: cl-z-")
def cloze(word):
for line in f:
match = True
if len(line) == len(word):
for i in range(len(word)):
if not word[i] == "-":
if line[i] == word[i]:
match == False
if match == True:
print(line)
while True:
cloze(input())

Once you've iterated through the file for the first word, the file closes. You'll need to save f. For example:
with open("C:\\my folders\\brit-a-z.txt", 'r') as f:
f = f.read().splitlines()

Return value as bool from text file

Trying to write multi scripts that would access one text file to retrieve their toggle values from the said text file and then return with a value as false and change it to true and vice versa.
Value always comes back as false, not sure what I'm missing but here is the text file:
1
False
3
True
5
6
7
8
9
Here is the source code:
def append():
with open('values', 'r') as file:
# read a list of lines into data
data = file.readlines()
# now change the line
re_value = value
data[1] = re_value+"\n"
# and write everything back
with open('values', 'w') as file:
file.writelines(data)
print("value changed to "+re_value)
def read() -> bool:
#opens the value file to find the value of the toggle
f=open("values", "r")
for x, line in enumerate(f):
if x == 1:
toggle = line
print(toggle)
return toggle
f.close()
toggle = read()
if toggle:
print("Light is on turn it off")
#runs command to turn off the light
#runs command to change value for light
value = "False"
append()
else:
print("Light is off turn it on")
#runs command to turn on the light
#runs command to change value for light
value = "True"
append()

Seems like the boolean value you are using to evaluate the condition is a string.
In this case you could keep it as string:
if value == "True":
print "Condition is true!"
Or implement something similar:
def str2bool(v):
return v.lower() in ("true",) # you can add to the tuple other values that you consider as true if useful
print str2bool(value)

Try this to toggle:
putback=[]
with open('values', 'r') as file:
for e in file.readlines():
if e=='True' or e=='False':
print(e)
putback.append(not e)
else:
putback.append(e)
with open('values','w') as file1:
file.write('\n'.join(putback))

Found my mistake guys, thank you for the help, changed the if statement to
if toggle=="True\n":
print("Light is on turn it off")
#runs command to turn off the light
#runs command to change value for light
value = "False"
append()
it was missing the new line tag as it is a multiline text document

From what i can understand you want to change True as False and False as True and leave the rest as it is.
final_output = []
with open("values") as file:
data = file.readlines()
for line in data:
line = eval(line.strip())
if isinstance(line, bool):
print("Value is {0} Changing to {1}".format(line, not line))
final_output.append(not line)
else:
final_output.append(line)
with open("values", 'w') as file:
file.write("\n".join([str(line) for line in final_output]))

How to search a string in JS file (multiple lines) in python? [duplicate]

I want to check if a string is in a text file. If it is, do X. If it's not, do Y. However, this code always returns True for some reason. Can anyone see what is wrong?
def check():
datafile = file('example.txt')
found = False
for line in datafile:
if blabla in line:
found = True
break
check()
if True:
print "true"
else:
print "false"

The reason why you always got True has already been given, so I'll just offer another suggestion:
If your file is not too large, you can read it into a string, and just use that (easier and often faster than reading and checking line per line):
with open('example.txt') as f:
if 'blabla' in f.read():
print("true")
Another trick: you can alleviate the possible memory problems by using mmap.mmap() to create a "string-like" object that uses the underlying file (instead of reading the whole file in memory):
import mmap
with open('example.txt') as f:
s = mmap.mmap(f.fileno(), 0, access=mmap.ACCESS_READ)
if s.find('blabla') != -1:
print('true')
NOTE: in python 3, mmaps behave like bytearray objects rather than strings, so the subsequence you look for with find() has to be a bytes object rather than a string as well, eg. s.find(b'blabla'):
#!/usr/bin/env python3
import mmap
with open('example.txt', 'rb', 0) as file, \
mmap.mmap(file.fileno(), 0, access=mmap.ACCESS_READ) as s:
if s.find(b'blabla') != -1:
print('true')
You could also use regular expressions on mmap e.g., case-insensitive search: if re.search(br'(?i)blabla', s):

As Jeffrey Said, you are not checking the value of check(). In addition, your check() function is not returning anything. Note the difference:
def check():
with open('example.txt') as f:
datafile = f.readlines()
found = False # This isn't really necessary
for line in datafile:
if blabla in line:
# found = True # Not necessary
return True
return False # Because you finished the search without finding
Then you can test the output of check():
if check():
print('True')
else:
print('False')

Here's another way to possibly answer your question using the find function which gives you a literal numerical value of where something truly is
open('file', 'r').read().find('')
in find write the word you want to find
and 'file' stands for your file name

if True:
print "true"
This always happens because True is always True.
You want something like this:
if check():
print "true"
else:
print "false"
Good luck!

I made a little function for this purpose. It searches for a word in the input file and then adds it to the output file.
def searcher(outf, inf, string):
with open(outf, 'a') as f1:
if string in open(inf).read():
f1.write(string)
outf is the output file
inf is the input file
string is of course, the desired string that you wish to find and add to outf.

Your check function should return the found boolean and use that to determine what to print.
def check():
datafile = file('example.txt')
found = False
for line in datafile:
if blabla in line:
found = True
break
return found
found = check()
if found:
print "true"
else:
print "false"
the second block could also be condensed to:
if check():
print "true"
else:
print "false"

Two problems:
Your function does not return anything; a function that does not explicitly return anything returns None (which is falsy)
True is always True - you are not checking the result of your function
.
def check(fname, txt):
with open(fname) as dataf:
return any(txt in line for line in dataf)
if check('example.txt', 'blabla'):
print "true"
else:
print "false"

How to search the text in the file and Returns an file path in which the word is found
(Как искать часть текста в файле и возвращять путь к файлу в котором это слово найдено)
import os
import re
class Searcher:
def __init__(self, path, query):
self.path = path
if self.path[-1] != '/':
self.path += '/'
self.path = self.path.replace('/', '\\')
self.query = query
self.searched = {}
def find(self):
for root, dirs, files in os.walk( self.path ):
for file in files:
if re.match(r'.*?\.txt$', file) is not None:
if root[-1] != '\\':
root += '\\'
f = open(root + file, 'rt')
txt = f.read()
f.close()
count = len( re.findall( self.query, txt ) )
if count > 0:
self.searched[root + file] = count
def getResults(self):
return self.searched
In Main()
# -*- coding: UTF-8 -*-
import sys
from search import Searcher
path = 'c:\\temp\\'
search = 'search string'
if __name__ == '__main__':
if len(sys.argv) == 3:
# создаем объект поисковика и передаем ему аргументы
Search = Searcher(sys.argv[1], sys.argv[2])
else:
Search = Searcher(path, search)
# начать поиск

# получаем результат
results = Search.getResults()
# выводим результат
print 'Found ', len(results), ' files:'
for file, count in results.items():
print 'File: ', file, ' Found entries:' , count

If user wants to search for the word in given text file.
fopen = open('logfile.txt',mode='r+')
fread = fopen.readlines()
x = input("Enter the search string: ")
for line in fread:
if x in line:
print(line)

found = False
def check():
datafile = file('example.txt')
for line in datafile:
if blabla in line:
found = True
break
return found
if check():
print "true"
else:
print "false"

found = False
def check():
datafile = file('example.txt')
for line in datafile:
if "blabla" in line:
found = True
break
return found
if check():
print "found"
else:
print "not found"

Here's another. Takes an absolute file path and a given string and passes it to word_find(), uses readlines() method on the given file within the enumerate() method which gives an iterable count as it traverses line by line, in the end giving you the line with the matching string, plus the given line number. Cheers.
def word_find(file, word):
with open(file, 'r') as target_file:
for num, line in enumerate(target_file.readlines(), 1):
if str(word) in line:
print(f'<Line {num}> {line}')
else:
print(f'> {word} not found.')
if __name__ == '__main__':
file_to_process = '/path/to/file'
string_to_find = input()
word_find(file_to_process, string_to_find)

"found" needs to be created as global variable in the function as "if else" statement is out of the function. You also don't need to use "break" to break the loop code.
The following should work to find out if the text file has desired string.
with open('text_text.txt') as f:
datafile = f.readlines()
def check():
global found
found = False
for line in datafile:
if 'the' in line:
found = True
check()
if found == True:
print("True")
else:
print("False")

Python Check list line by line

My problem is following:
def searchWordlist():
path = str(raw_input(PATH))
word = str(raw_input(WORD))
with open(path) as f:
for line in f:
if word in line:
print "Word found"
Than I added following code:
else:
print "Word not found"
But this obviously can't work, because it will print "Word not found" until the word is found. Well.. but how can I print that the word is not found?! I srsly don't know.
Thank you in advance!

Python has a special trick for this kind of thing:
for line in f:
if word in line:
print "Word found"
break
else:
print "Word not found"
Here the else goes with the for, and specifically executes if the loop completes normally without hitting a break.

If all you want it to do is to print whether word is found in any of the lines:
def searchWordlist():
path = str(raw_input(PATH))
word = str(raw_input(WORD))
with open(path) as f:
if any(word in line for line in f):
print('Word found')
else:
print('Word not found')

def searchWordlist():
path = str(raw_input(PATH))
word = str(raw_input(WORD))
loc = -1
with open(path) as f:
for i, line in enumerate(f):
if word in line:
loc = i
break
if loc >= 0:
print ("Word found at line {}".format(loc))
else:
print ("Word not found")
As a bonus, this keeps track of where in the file the word in first seen, if at all.

You can get your function to return as soon as it finds the word if you only need to find the first occurrence. This has the added bonus of not having to loop through the whole file if it doesnt need to
def searchWordlist():
path = str(raw_input(PATH))
word = str(raw_input(WORD))
with open(path) as f:
for line in f:
if word in line:
print "Word found"
return 1
print "Word not found"
return 0

def searchWordlist():
found_word = False
path = str(raw_input(PATH))
word = str(raw_input(WORD))
with open(path) as f:
for line in f:
if word in line:
print "Word found"
found_word = True
if not found_word:
print "Word not found!"
What this code does is it executes your code as normal, except that if it finds the word it sets a boolean to true, signifying that it has found the word. It then, after completely parsing the file, sees if the word was found, if the variable is true. If the word was not found, then it prints that the word was not found. If you want the code to stop after the word is found for the first time, but break after found_word = True.

Tricks between plain python script and functions?

As a very newbie to programming, I tried to test every function individually, make sure it works right.
Here is my problem: for single plainly test, it works; turn it to functions and combine them into a script, them don't work.
For example:
def getRigs (fileObj):
fileObj.seek(0)
rigList = []
Tag = False
for line in fileObj:
if line.find("[BeginRigs]") != -1:
Tag = True
elif line.find("[EndRigs]") != -1:
Tag = False
elif Tag:
rigList.append(line.strip())
return (rigList)
def getObjects (fileObj):
fileObj.seek(0)
objList = []
Tag = False
for line in fileObj:
if line.find("[BeginObjects]") != -1:
Tag = True
elif line.find("[EndObjects]") != -1:
Tag = False
elif Tag:
objList.append(line.strip())
return (objList)
def dummyRig (rigObj, objName):
dummy = ""
for rig in rigObj:
with open(rig, "r") as infile:
#rigObj.seek(0)
Tag = None
for line in infile:
for obj in objName:
if line.find("ObjectAlias " + obj + "\n") !=-1:
Tag = "Mark"
dummy += line
break
elif line.find("BeginKeyframe") != -1:
if Tag == "Mark":
Tag = "Copy"
break
elif line.find("EndKeyframe") != -1:
if Tag == "Copy":
Tag = None
dummy += line
break
if Tag == "Copy":
dummy += line
return (dummy)
def getBlock (rigObj, objName):
Tag = False
block = ""
for line in rigObj:
if line.find("ObjectAlias " + str(objName) + "\n") != -1:
for line in rigObj:
if line.find("BeginKeyframe") != -1:
Tag = True
elif line.lstrip().startswith("0.000 ") and line.rstrip().endswith("default"):
Tag = False
break
elif Tag:
block += line
return (block)
inputconfig = open("config.cfg", "r")
infile = sys.argv[1]
inputscene = open(infile, "r")
outfile = infile.split(".")[0] + "_updated.fxs"
outputscene = open(outfile, "w")
a_rigList = getRigs (inputconfig)
a_objList = getObjects (inputconfig)
a_dummyRig = dummyRig (a_rigList, a_objList)
#print a_dummyRig #----> Output as expected
tmp = getBlock (a_dummyRig, a_objList)
outputscene.write(tmp) #----> Gvie me empty output!
If I test "getBlock" function individually, it works fine:
with open("result_from_a_dummyRig", "r") as rigObj, open("result", "w") as output:
Tag = False
for line in rigObj:
if line.find("ObjectAlias " + "rooster_bn_featherLa_rt_08" + "\n") != -1:
for line in rigObj:
if line.find("BeginKeyframe") != -1:
Tag = True
elif line.lstrip().startswith("0.000 ") and line.rstrip().endswith("default"):
Tag = False
break
elif Tag:
output.write(line)
What am I doing wrong?
EDIT: Add more of my code, hope it helps for the question. The code is design for copy some external data from other files to update my current files.
Thanks bruno, I got your point. The dummyRig function give me a string but not a "real" file. And getBlock function needs a "real" file input. Right?
Still hope someone give me more useful helps, I am not a programmer, I don't know much about python.

In your "test", you are iterating over an opened file. The file iterator iterate over the file's lines.
In your script, what you're passing to getBlock is a string, so you're iterating over the string's individual characters. No surprise you don't get the same results.
If you want getBlock to be able to work on both an opened file OR some arbitray string, you have to wrap the string in some file-like object that will iterate over line, not chars. The stdlib's StringIO module comes to mind...
Also if you really want to be serious about tests, use some automated unittest framework (unittest might not be the most sexy but it's in the stdlib) and make sure you really test the same thing that you will pass to your function ;)
