I am relatively new to python and was working on a project to enhance my skills, it was a text file compressor; I am having problems with the file scanning portion, I want it to read a text file and find a word. Any help would be much appreciated.
My code:
def check():
datafile = file("res\powerserv 1.txt")
for line in datafile:
if storage in line:
return true
else:
return false
The main issue with your code is the return False inside the for loop.
Assuming this is your file:
word1
word2
word3
You are looking for word3. Now, this is what your program does:
word3 == word1 ?
No, so break
What you need is:
word3 == word1 ?
No, next iteration
word3 == word2 ?
No, next iteration
word3 == word3 ?
return True
This is how your code should be:
def check(word):
with open("res\powerserv 1.txt") as datafile:
for line in datafile:
if word in line:
return True
return False
print(check('your word'))
The return False comes outside the loop. Also, consider the use of the with...as context manager to handle opening and closing of your files.
