I just ran into this issue and had trouble filling in the “holes” left in the above example. Here’s a more complete, working version that I used. Hopefully this helps someone: # Custom formatter class MyFormatter(logging.Formatter): err_fmt = “ERROR: %(msg)s” dbg_fmt = “DBG: %(module)s: %(lineno)d: %(msg)s” info_fmt = “%(msg)s” def __init__(self, fmt=”%(levelno)s: %(msg)s”): logging.Formatter.__init__(self, fmt) … Read more
Console.WriteLine(DateTime.Now.ToString(“ddd M/dd/yy”, CultureInfo.InvariantCulture)); Console.ReadLine(); try the above

You can use str.format() to apply values to that template: name=[“deep”,”mahesh”,”nirbhay”] user_input = “certi_{element}” # this string i ask from user for value in name: print(user_input.format(element=value)) String formatting placeholders … Read more
The g formatter limits the output to n significant digits, dropping trailing zeroes: >>> “{:.3g}”.format(1.234) ‘1.23’ >>> “{:.3g}”.format(1.2) ‘1.2’ >>> “{:.3g}”.format(1) ‘1’
Check out the inflect package. It will pluralize things, as well as do a whole host of other linguistic trickery. There are too many situations to special-case these yourself! From the docs at the link above: import inflect p = inflect.engine() # UNCONDITIONALLY FORM THE PLURAL print(“The plural of “, word, ” is “, p.plural(word)) … Read more
Sorry for posting to such an old thread — but as someone who also shares a passion for pythonic ‘best’, I thought I’d share our solution. The solution is to build SQL statements using python’s String Literal Concatenation (http://docs.python.org/), which could be qualified a somewhere between Option 2 and Option 4 Code Sample: sql = … Read more
The formatting routine that VB6 uses is actually built into the operating system. Oleaut32.dll, the VarFormat() function. It’s been around for 15 years and will be around for ever, considering how much code relies on it. Trying to translate the formatting strings to a .NET composite formatting string is a hopeless task. Just use the … Read more
