Currently I am trying to open a text file called "temperature.txt" i have saved on my desktop using file handler, however for some reason i cannot get it to work. Could anyone tell me what im doing...
I'm looking at how to do file input and output in Python. I've written the following code to read a list of names (one per line) from a file into another file while checking a name against the names in the file and appending text to the occurrences in the file.
I am very new to programming and the python language. I know how to open a file in python, but the question is how can I open the file as a parameter of a function? example: function (parameter) ...
Anyways, I'm working on a piece of code that will open a file, print out the contents on the screen, ask you if you want to edit/delete/etc the contents, do it, and then re-print out the results and ask you for confirmation to save. I'm stuck at the printing the contents of the file. I don't know what command to use to do this.
On a technical level, there are some things you may want to do with a file handle in Python which would not work as well if iteration closed the file handle. For example, suppose I need to iterate over the file twice:
On some operating systems, opening the file with 'a' guarantees that all your following writes will be appended atomically to the end of the file (even as the file grows by other writes). A few more details about how the "a" mode operates (tested on Linux only). Even if you seek back, every write will append to the end of the file:
186 In Python, when given the URL for a text file, what is the simplest way to access the contents off the text file and print the contents of the file out locally line-by-line without saving a local copy of the text file?
3 The open() built-in Python method (doc) uses normally two arguments: the file path and the mode. You have three principal modes (the most used): r, w and a.
912 Rather than mess with .encode and .decode, specify the encoding when opening the file. The io module, added in Python 2.6, provides an io.open function, which allows specifying the file's encoding. Supposing the file is encoded in UTF-8, we can use:
