readfile

问题 Now I use: pageHeadSectionFile = open(\'pagehead.section.htm\',\'r\') output = pageHeadSectionFile.read() pageHeadSectionFile.close() But to make the code look better, I can do: output = open(\'pagehead.section.htm\',\'r\').read() When using the above syntax, how do I close the file to free up system resources? 回答1: You don't really have to close it - Python will do it automatically either during garbage collection or at program exit. But as @delnan noted, it's better practice to explicitly

问题 I need to read a text file when I start my program. I\'m using eclipse and started a new java project. In my project folder I got the \"src\" folder and the standard \"JRE System Library\" + staedteliste.txt... I just don\'t know where to put the text file.

I use the following code to read the file, but I get this error: Error:java.io

问题 I wrote a bunch of code in Haskell to create an index of a text. The top function looks like this: index :: String -> [(String, [Integer])] index a = [...] Now I want to give this function a String read from a file: index readFile \"input.txt\" Which won\'t work because readFile is of type FilePath -> IO String. Couldn\'t match expected type \'String\' against inferred type \'IO String\' I see the error, but I can\'t find any function with type: IO String -> String I guess the key to success

问题 I have two text files in two different languages and they are aligned line by line. I.e. the first line in textfile1 corresponds to the first line in textfile2, and so on and so forth. Is there a way to read both file line-by-line simultaneously? Below is a sample of how the files should look like, imagine the number of lines per file is around 1,000,000. textfile1: This is a the first line in English This is a the 2nd line in English This is a the third line in English textfile2: C\'est la
