Python Error Int Argument Required

lucius Guest I am trying to print some values to a file (using c's printf like method). To get this behavior, the value 'resolve' can be supplied to the conflict_handler= argument of ArgumentParser: >>> parser = argparse.ArgumentParser(prog='PROG', conflict_handler='resolve') >>> parser.add_argument('-f', '--foo', help='old foo help') >>> for options like +f or /foo, may specify them using the prefix_chars= argument to the ArgumentParser constructor: >>> parser = argparse.ArgumentParser(prog='PROG', prefix_chars='-+') >>> parser.add_argument('+f') >>> parser.add_argument('++bar') >>> parser.parse_args('+f So surely I have provided an int argument. http://caribtechsxm.com/python-error/python-error-log-mac.php

Sign up now! It should not accept 42.0. This can be achieved by passing False as the add_help= argument to ArgumentParser: >>> parser = argparse.ArgumentParser(prog='PROG', add_help=False) >>> parser.add_argument('--foo', help='foo help') >>> parser.print_help() usage: PROG [--foo FOO] Parsing arguments¶ ArgumentParser parses arguments through the parse_args() method. http://stackoverflow.com/questions/1180673/python-error-int-argument-required

Then, excecute the two segments of code for int and long objects. These can be handled by passing a container object as the choices keyword argument to add_argument(). The default keyword argument of add_argument(), whose value defaults to None, specifies what value should be used if the command-line argument is not present. Invalid arguments¶ While parsing the command line, parse_args() checks for a variety of errors, including ambiguous options, invalid types, invalid options, wrong number of positional arguments, etc.

First, use %s and not %i. In the simplest case, the option and its value are passed as two separate arguments: >>> parser = argparse.ArgumentParser(prog='PROG') >>> parser.add_argument('-x') >>> parser.add_argument('--foo') >>> parser.parse_args(['-x', 'X']) Namespace(foo=None, x='X') >>> parser.parse_args(['--foo', 'FOO']) sqrt = math.sqrt(value) ... https://docs.python.org/3/library/argparse.html That doesn't excuse sprinkling several million backslashes through literal constants when there's a more readable alternative. -- Rhodri James *-* Wildebeest Herder to the Masses Rhodri James, Jun 14, 2009

For example, an optional argument could be created like: >>> parser.add_argument('-f', '--foo') while a positional argument could be created like: >>> parser.add_argument('bar') When parse_args() is called, optional arguments will be While it's arguably not-quite-sane to have code that triggers this error, the inconsistency is what concerns me.

I still remember asking a friend, "Why is your code jagged like that?" and him looking at me a bit confused at the question. Example usage: >>> parser = argparse.ArgumentParser() >>> parser.add_argument('--foo', action='append') >>> parser.parse_args('--foo 1 --foo 2'.split()) Namespace(foo=['1', '2']) 'append_const' - This stores a list, and appends the value specified by the const Lawrence D'Oliveiro, Jun 17, 2009 #11 Rhodri James Guest On Wed, 17 Jun 2009 12:07:15 +0100, Lawrence D'Oliveiro <_zealand> wrote: [snip example code] > You haven't managed to get rid of By default, the argument strings are taken from sys.argv, and a new empty Namespace object is created for the attributes. 16.4.4.1.

Try replacing the %f & %d strsubs with %s and see if that works. (You shouldn't need to typecast the values if you're just reinserting them into a string...) alex23, have a peek at these guys Can I only touch other creatures with spells such as Invisibility?

The attached patch first checks for a number; if it's a number but not PyInt nor PyLong, tries to convert to int; if it fails, tries to convert to long. Yes, yes, you can print them at any size. likewise for this epilog whose whitespace will ... action - The basic type of action to be taken when this argument is encountered at the command line.

The __call__ method may perform arbitrary actions, but will typically set attributes on the namespace based on dest and values. 16.4.4.
