UPDATE Back in my naïve days, I suggested doing this manually (it was a simple solution to a simple question), however due to this becoming more and more popular, I’d recommend using the library CsvHelper that does all the safety checks, etc. CSV is way more complicated than what the question/answer suggests. Original Answer As you already … Read more
I believe that should do what you need.
.S files are source code files written in assembly. Assembly is an extremely low-level form of programming. The files contain assembly instructions to the processor in sequential order and are typically compiled based on a selected architecture. Examples of such files are often seen in the linux kernel for specific architectures, e.g. x86, sparc, ARM, … Read more
Loop over the file to read lines: File objects are iterable and yield lines until EOF. Using the file object as an iterable uses a buffer to ensure performant reads. You can do the same with the stdin (no need to use raw_input(): To complete the picture, binary reads can be done with: where chunk … Read more
The server certificate is invalid, either because it is signed by an invalid CA (internal CA, self signed,…), doesn’t match the server’s name or because it is expired. Either way, you need to find how to tell to the Python library that you are using that it must not stop at an invalid certificate if … Read more
I want to prompt a user for a number of random numbers to be generated and saved to a file. He gave us that part. The part we have to do is to open that file, convert the numbers into a list, then find the mean, standard deviation, etc. without using the easy built-in Python … Read more
Here’s how you read a file, and then write to it (overwriting any existing data), without closing and reopening:
Python has the pickle module just for this kind of thing. These functions are all that you need for saving and loading almost any object: In order to save collections of Python there is the shelve module.
I guess something like this should do it. It basically writes the content to a new file and replaces the old file with the new file:
MS provides the OpenXML SDK V 2.5 – see https://msdn.microsoft.com/en-us/library/bb448854(v=office.15).aspx This can read+write MS Office files (including Excel)… Another option see http://www.codeproject.com/KB/office/OpenXML.aspx IF you need more like rendering, formulas etc. then there are different commercial libraries like Aspose and Flexcel…
