I would suggest reconstructing your JSON with renamed properties. I don’t think you should worry about speed penalties as it’s usually not an issue. Here’s how you can do it. public static JToken Rename(JToken json, Dictionary<string, string> map) { return Rename(json, name => map.ContainsKey(name) ? map[name] : name); } public static JToken Rename(JToken json, Func<string, … Read more
df.rename has a parameter called columns that accepts dictionaries: df.rename(columns=dict(zip(df2[“val1”], df2[“val2”]))) Out: A7 B0 C3 D1 0 1 2 3 4 1 5 6 7 8 It returns a new DataFrame. You can either use inplace=True, or assign it back to the original DataFrame.
Python import os path=”/path/to/files/” for filename in os.listdir(path): prefix, num = filename[:-4].split(‘_’) num = num.zfill(4) new_filename = prefix + “_” + num + “.png” os.rename(os.path.join(path, filename), os.path.join(path, new_filename)) you could compile a list of valid filenames assuming that all files that start with “output_” and end with “.png” are valid files: l = [(x, “output” … Read more
Try: header(‘Content-Disposition: attachment; filename=”July Report.pdf”‘); or header(‘Content-Disposition: inline; filename=”July Report.pdf”‘); Another option would be to use the $_SERVER[‘PATH_INFO’] to pass your “July Report.pdf” – an example link might be: <a href=”https://stackoverflow.com/questions/2015985/report_pdf.php/July%20Report.pdf?month=07″> That file should default to saving as “July Report.pdf” – and should behave exactly like your old php script did, just change the code … Read more
Git doesn’t track renames at all, but uses heuristic to re-discover them during merge etc. Mercurial tracks renames (the origin version and origin file is recorded) and uses that information during merges. So you have to explicitly tell hg about renames with hg mv, or use hg addremove –similarity for auto-discovery. There has been some … Read more
There is no difference between moving and renaming; you should simply call Directory.Move. In general, if you’re only doing a single operation, you should use the static methods in the File and Directory classes instead of creating FileInfo and DirectoryInfo objects. For more advice when working with files and directories, see here.
If your filenames contain no whitepace and you don’t have any subdirectories, you can use a simple for loop: $ for FILENAME in *; do mv $FILENAME Unix_$FILENAME; done Otherwise use the convenient rename command (which is a perl script) – although it might not be available out of the box on every Unix (e.g. … Read more
