How to remove double quotes from a text file in python

We have a routine on our website that needs to pull information from a text file. The file is a tab delimited file with double quotes surrounding the text.

The routine needs to compare these values to another imported list of values that do not have the double quotes around the text. I have been able to get the information imported to a hash but the double quotes are still there. Is there anyway to use the qw operator to accomplish this? In the above example there is nothing to remove.

I know you know that yourself. I do know that print; will not remove quotes from data stored in a hash, but I don't see any hash in your example. Perhaps you meant to define a character class and forgot the square brackets? An example of removing quotes from data read from a tab-delimited file before storing that data in a hash would be something like. Comparing these keys to another list in another hash could be done pretty much as in mitchems example.

If you split on "," and remove beginning and end quotes. You want simple one.

Check this out. It will, but it doesn't answer the question of removing quotes in a hash. Well sorry to divert a little from here. An example of removing quotes from data read from a tab-delimited file before storing that data in a hash would be something like! Value is not defined.

Hey, RH. After giving this considerable thought, however, the Scripting Guys have decided that we would like to help Google out as best we can. What RH would like to have is a CSV file with data similar to this, with just a single set of double quotes surrounding each item:.

Next we create an instance of the Scripting. Once the file is open we then use the ReadAll method to read in the entire file and store the contents in a variable named strContents:. Because of that, we need to read the file and store the contents in memory; we can then do a search-and-replace operation on that copy of the file. Got that? Instead, we have to close it, then reopen it for writing. Yes, that is kind of silly. We do that to help prevent anyone who reads our script from getting a headache; because double quotes are a reserved character in VBScript the only way to search for double double quotes is to store those double double quotes inside another pair of double double quotes.

Something like this:. Therefore, we sidestep the problem of embedding quotes within quotes within quotes by, instead, searching for consecutive instances of Chr 34 :. Therefore, in addition to defining the target text, we also need to define the replacement text.

Needless to say, that happens to be a single instance of Chr 34 :. Now, at long last, we can call the Replace function, passing this function — in order — the string value we want to search the variable strContents ; the target text we want to search for strFindText ; and the text we want to use to replace the target text strReplaceText.

How to Write to a Text file with Double quotes?

That all sounds very complicated, but it really requires just a single line of code:. Execute this line of code, and the variable strContents will contain a corrected copy of the text file, a copy that has all the doubled-up double quotes removed. Once we have that we can reopen the file Test. The rest is easy: we call the WriteLine method to replace the existing contents of the file with the value stored in strContents, and then close the file.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

However, the string "bill" does not contain any quotes, so this doesn't test anything. If you try print stryou'll see it never had quotes in the first place - this is because the quotes mark that str is a string, and are therefore not included.

You wouldn't always want quotes in your strings. However, this doesn't explain the real issue in your other program.

I have a python Code that will recognize speech using the Google STT engine and give me back the results but I get the results in strings with "quotes". I don't want that quotes in my code as I will use it to run many commands and it doesn't work. I haven't tried anything so far as I didn't get anything to try!

This is the function in the python code that will recognize speech:. Just use string methods. You can make use of the builtin string function. You can use the string function. You can use a regular expression to remove all quotes from given string.

This has the added advantage of letting you have control over when and where a quote should be deleted:. Learn more. Remove quotes from String in Python Ask Question. Asked 3 years, 4 months ago. Active 9 days ago.

I have a text file and on some of the rows I have a column where the string begins with a double quote " and ends with a double quote ". I need to be able to remove the beginning double quote, which always starts in the same position column 6and the ending double quote, which will be in a different position, depending on the length of the string.

Also within the string inside the outer double quotes I may have other double quotes that need to be preserved and not modified. I'm not sure if this is something that can be accomplished using expressions, and if so what are the necessary search and replace strings. Thanks in advance. Power User.

Hi, another double quotes beyond the ending one are allowed? Are the inner double quotes prefixed by some special character backslash, Grand Master. I explain the Perl regular expression posted by Fleggy. A line with sixth character being a double quote, but having no more double quote character is ignored by this search expression.

Hi Fleggy - I tried that but it did not seem to work. Well, the first double quote is not in column 6 but in 7. Awesome this worked great! Back to top. OK Join.

Assuming that each line of a CSV text file is a new row is hugely naive because of all the edge cases that arise in real-world dirty data.

Split the string into lines of text, then pass into csv. Use csv. Try the above snippet in the interactive shell, and test out what records actually is. We could use a regular expression to extract the pattern that represents the age a number at the end of the line. But we could also do something simpler: split the row string by commawhich gives us a list of strings.

And then the age value is the last value in that list:. How are commas that are part of a data field handled?

In some situations by double quoting the field:. But what happens when a text field contains a comma and double quotes? Then you need to double-quote the field.

But when we realize that there are many ways for text data to get messy — including the inclusion of newline characters within a column, rather than just what we use to delimit rows — then it becomes obvious the official CSV specification is more or less considered a disaster.

Certainly, it is not possible to sanely extract data from CSV-formatted text using the string split method and regular expressions alone. It needs to be structured text — text without structure is just noise. But when there is structure, then we can turn text into data objects — particularly, lists and dictionaries — that we can use in our programs.

Conversely, if you have lists and dicts in Python, you can serialize them to be stored as text, which means you can port your data objects in such a way that someone else can deserialize and import them for their own programs. Or at least it did for me — not until very late in my Python programming experience did it make sense to me why all the steps for converting raw text into data objects via csv were needed.

And virtually all of the important data we deal with is text from someone else that we need to import into our program. First, to bring the csv library into our programs, we have to import it.
